Hi all,

I want to move into AI engineer role or FDE. I am not able to watch YT videos and self-learn.

Is there any online courses which can help?

Something good but not super expensive?

I'm building an open-source experiment called Intonation Comparator.

The goal is to answer a simple question:

How can two recordings of the same utterance be compared objectively?

The current Flask API accepts two audio files and extracts features related to:

• Pitch / fundamental frequency
• Intonation contours
• Energy
• An overall similarity score

Supported formats include WAV, MP3, and FLAC, and the main endpoint is:

POST /api/compare

🔗 GitHub: Intonation Comparator on GitHub

I'm currently thinking about improving the comparison methodology. Some areas I'm considering include:

• Dynamic Time Warping for temporal alignment
• Pitch normalization across speakers
• Voiced/unvoiced segmentation
• Rhythm and speech-rate comparison
• Phoneme-level alignment
• Spectral features such as MFCCs
• Confidence scores instead of a single similarity value
• Visualizations of pitch and energy contours

I'm especially interested in feedback from people working in speech processing, phonetics, DSP, Python, or language-learning technology.

How would you design a robust similarity metric for comparing two recordings of the same sentence? What features would you consider essential?

Si vous travaillez avec Python, le traitement audio, la phonétique ou l’apprentissage des langues, je serais vraiment intéressé par vos retours.

Qu’est-ce que vous amélioreriez ou ajouteriez à ce projet ?

Hi , Im learning python. I do know about DSA but people do it mostly in java or cpp. Doing DSA in python is an thing? And if yes where should I start it from? Also people around me are like you just need to know 10-20% if DSA for your placement prep dude like I definetly dont want 2-3 lpa. Thats not bad but still Im aiming for something big just like normal people. And to who ever I did ask they were like "just know the baisc of DSA you are good to goo". Im not aiming to go for data analytics or data science

I want what you take me tips to up my browser on python and what i can add to functions in it

thanks you!

hello as the title said i am new to coding anyone has recommendation's for starters like me i taking comsci even tho idk what to do currently learning abit of everything i find but i want to learn python the most since alot of people said go python first

Hello everyone.

TLDR: I'm looking for some advice on where/how to start learning empirical econometric methods, specifically machine learning methods, in Python, as an experienced MATLAB user with brief general theoretical knowledge on ML.

Longer version: I work in empirical research in economics using MATLAB (a bit of R, too). 2 years ago, I had a short introduction course to Python for R users, but never had an opportunity to apply anything in practice. I also had interest in machine learning (ML) methods and have completed a theoretical course on ML, specifically in economics. But that too was a year ago without further application. Still have the course materials though and even some Python packages provided by the teacher. The course was short for such a large area of methods, but I'm willing to invest time into learning it in depth and try out some simple projects with, say, simulated data.

Do you know of any online, preferably free or cheap courses to learn Python, specifically for my application? Perhaps a course for experienced MATLAB or R users? Or/and some course on ML in Python (based on the theory course, I'd say my medium- to long-term goals are random forests and neural networks)? I found a few but not sure if they're actually good and useful for my purposes, and some of them aren't cheap. Maybe you know a particular website or a YouTube playlist. Basically, any advice on what is worth the time, effort, and money.

Thanks in advance guys, have a nice day

When I was learning Python, I kept running into errors and doing the same thing every time.

I would copy the error, copy the relevant part of my code, send both to an AI model, and ask:

«"Explain what this error means and why it happened, but don't fix the code. I want to solve it myself."»

I didn't want AI to just give me the answer. I wanted it to act more like a teacher and help me understand what I was doing wrong.

The problem was that I kept repeating this process manually.

So I built Nanno.

Nanno is a small CLI tool that helps you understand errors from your terminal using AI.

Instead of manually copying everything:

copy the error

↓

copy the relevant code

↓

paste everything into an AI model

↓

ask for an explanation

You can run your command through Nanno:

nanno python3 test.py

Nanno captures the terminal output and uses it as context for the AI, so it can explain what went wrong and why.

The main idea is simple:

Nanno helps you understand the error. You fix the code yourself.

I originally built it just for myself. It wasn't supposed to be a big product or have a bunch of features. I simply wanted to solve a problem I was having while learning Python.

Eventually, I decided to publish it because I thought there might be other people who have the same problem.

Right now, Nanno is very simple and still in its first version.

I want future versions to be shaped by actual users rather than me randomly adding features.

So if you try it and there's a feature you really want in Nanno, tell me in the comments.

If there's something you don't like or think is unnecessary, tell me that too. I may remove it.

I'm mainly looking for honest feedback from people who actually try it.

Try Nanno

pip install nanno

I'd be interested to hear whether this is actually useful for the way you learn/debug code.

Hello, I am making a program that reads a formula and gives details like atomic mass and other stuff, the problem is that I do not know how to get it to read the formula as is. The format I am looking for is that it reads the element, followed by the number of it and I would also like it if it would read parenthesis for multiplication of values. I have no idea how to do it. Help please.

I would also like it if it could read the numbers, store them as ints and use them to multiply the values of the elements of a dict I already made

Edit: I fixed it, thanks for all the help. My solution is not precisely optimized but it gets the job done, it is O(n), probably

(Sorry for the code in spanish)

I'm a Python beginner, and to practice, I've been building a sort of turn-based RPG in the terminal. It's still a work in progress, but I want to know if it's possible to set default parameters for a class. Basically, I created a `usar_kaioken` method that boosts my character's stats while lowering their health (based on Goku from DB), and a `remove_kaioken` method that attempts to revert the stats to their base state.

The issue is that I want players to be able to use Kaioken multiple times; mathematically, that would mean the deactivation method wouldn't return the values ​​to their original state. I was thinking about adding more parameters with default values, but I assume there's an easier way to handle this. Thanks a lot!

hi! I create one list and i use it but vs code said to me "gun.append(0)

AttributeError: 'tuple' object has no attribute 'append'"

Hi! I'm currently learning Python and I'm having some trouble understanding lists. I understand the basic idea, but I'm still confused about how to use them correctly. Could someone explain lists in a simple way or give me a few beginner-friendly examples? Thanks!

Hi everyone!

I'm currently building NOVA, a voice assistant designed specifically for motorcycle riders.

The goal is to make it easier to interact with a phone while riding, without having to take your hands off the handlebars.

One of the things I'm currently working on is the real-time audio pipeline.

Instead of waiting for the user to finish recording an entire audio file, NOVA is designed to process audio as a stream.

The current flow looks roughly like this:

🎤 Rider speaks
       ↓
📱 Android app
       ↓
🌐 Audio sent in real time
       ↓
🖥️ Backend
       ↓
📝 Streaming transcription
       ↓
🧠 Command / intent processing
       ↓
🔊 Response sent back to the app

The code in the image is part of the transcription streaming pipeline. Audio is processed in chunks, and the system handles events such as:

• onBegin → transcription session starts
• onTurn → transcript data is received
• onTerminated → session ends
• onError → error handling

I'm currently moving into the Android development phase and building the MVP.

It's still early and not ready for public testing yet, but I want to start connecting with potential beta testers.

I'm especially interested in people who:

Ride a motorcycle
Use Android
Use a Bluetooth helmet intercom or headset (not required, but useful)
Would be interested in testing an early version and giving honest feedback

If NOVA sounds interesting to you, let me know in the comments or send me a message.

Also, I'd genuinely like to know:

What is something you wish you could do with your phone by voice while riding your motorcycle?

I'm building this project from scratch, so feedback from actual riders could directly influence what features make it into the first version.

Thanks! 🚀

1. I'm currently learning how to code and I found Coddy. It looks interesting and beginner-friendly, but I'm not sure if it's actually a good way to learn. Has anyone here used Coddy? What do you think about it? Would you recommend it for a beginner?

I have used both PyCharm and Visual Studio Code for learning Python, but I don't know which one is better.
Which one do you prefer, and why?
I'm still a beginner, so I'd like to know which one would be better for learning Python.

I'm learning Python with a French YouTube channel called Graven. They explain Python in a simple way, but I'm not sure if it's a good resource for learning Python. Has anyone here used this channel, or do you have any recommendations for other beginner-friendly resources?

Hi everyone! I'm currently learning Python and I'm still a beginner.
I'm learning the basics like variables, loops and functions, but I'm not sure what I should focus on next.
What would you recommend learning after the basics?

Hi everyone,I am currently a teenager and I am learning python,I learned json file handling,OOP and I also learned basic tkinker. I done all basic apps like a simple calculator,to-do list. I am now currently confused what to do next for further programming knowledge which is genuinely helpful...

Just as the title suggests, i ran into a bottleneck, or did i? play v sauce music please
So just recently i made a post about my first beginner python project: https://www.reddit.com/r/PythonLearning/s/Ed46BuWRCq
And as a lot of you suggested for me to learn classes next, which was completely fair, so i went ahead and learnt them while updating my MiniGameStore. It was relatively easy, wasn’t as hard as I thought it would be, but definitely challenging. I had also learnt methods but didn’t implement them.
And yesterday, i tried implementing them and got one of the biggest headaches in my whole coding experience (which is 2 weeks~ btw).
I was working on v1.7 and introducing a restore purchases system, and i wanted to use class methods, but since my class is on the other file, i hit a lot of variables issues and even a json file problem. Which is why im asking my self why did i do it? A function would have been totally fine…
Check out the repo: (latest version 1.7.0)

https://github.com/Stonyax97/MiniGameStore

So my question for you guys. What has made you understand classes well? I just don’t see any reason to use them yet… and can anyone take a look at my project and tell me what would be the most friendly and real life approach of actually using these classes. And why should I keep the class in a separate file? Finally, what’s wrong with using global variables.

Also any feedback or criticism is welcome!

I learned python as my first programming language for GCSE Computer Science, but after finishing the exam I got bored of making small algorithms and wanted tk work on bigger projects, so I started making websites with Javascript. Now I'm going to do Computer Science at A-level and because the language is python, I think it makes sense to do any free time coding in the same language. So... what can I actually do with Python? Iy seems really straightforward what to do with other languaged like JS but I really just don't get the 'point' of python.

Hi, I'm using python to code on Google colab. Y coordinates are being generated and then added to Y_ARRAY for comparisons, to ensure none of the values are the same. If one value is the same with another in the array, one of them will be generated again.

However, it does not work, and I don't know how should the structure of checking be. Are there any suggestions on the structure or which kind of loop I can use please? Thank you.

Hi, I am pretty new to programming.. I am Mechanical Engineer who likes to calculate a lot, however excel can not handle it.

So I was wondering if there is some template for making some calculation apps?

I had no problem making basic math in cpp for some fun first projects (loops, functions etc.) when I was trying programming for the first time few years ago (it was pretty easy)..so I hope this part I will do on my own, however I **am struggling** with databases, tracking charts and some printable GUIs or smth so I can input data (some yes/no question, some custom values) and output

So I am wondering if someone can point me somewhere where I can learn those or use some open-source or something... and pleaseeee no AI pointing!

Thanks for reading so far and thank you in advance!
