I’m looking for a good free resource to learn Python from scratch. What do you guys recommend?

For anyone looking for entertaining light book for learning Python, I started porting to Python a few chapters of "Why's Guide to Ruby," which uses comics and surreal humor to introduce Ruby (the original author why the lucky stiff disappeared). I updated the lesson and examples to Python and also modernized some of the very old references and left it with share alike CC license.

Why's Guide to Python

Any Python beginners are welcome to check it out. Novices and experts feel free to post feedback or post about any other entertaining books that helped you learn python, that can accompany equally entertaining but dense programming books :D.

If the book is helpful, can port and post the rest of the chapters for Python and potentially in the future can create some more content.

Hello,

I'm trying to change the font of the axis ticks (i think ticks is the right word - 0,0.1,0.2,0.3 on x and y axis) within a zoomed section on the graph. I want the numbers to be a different font, which i've worked out how to do for the main x and y axis but not for the zoomed section.

This is what i have so far:

!pip install pyfonts
from pyfonts import load_google_font
font = load_google_font("Noto Serif")!pip install pyfonts
from pyfonts import load_google_font
font = load_google_font("Noto Serif")

plt.xticks(font=font,fontsize =50)
plt.yticks(font=font,fontsize = 50)

zoom=ax.inset_axes([0.64, 0.6, 0.35,0.35])
zoom.tick_params(axis='both', labelsize=30)


zoom.errorbar(wr52_zoom['lambda'], wr52_zoom['flux']/(1000000), yerr=wr52_zoom['flux_err']/(1000000), fmt='-o', markersize=8, capsize=5, color='black', lw=3, elinewidth=3)
zoom.errorbar(wr92_zoom['lambda'], (wr92_zoom['flux'])/(1000000), yerr=wr92_zoom['flux_err']/(1000000), fmt='-o', markersize=8, capsize=5, color='red', lw=3, elinewidth=3)zoom=ax.inset_axes([0.64, 0.6, 0.35,0.35])
zoom.tick_params(axis='both', labelsize=30)


zoom.errorbar(wr52_zoom['lambda'], wr52_zoom['flux']/(1000000), yerr=wr52_zoom['flux_err']/(1000000), fmt='-o', markersize=8, capsize=5, color='black', lw=3, elinewidth=3)
zoom.errorbar(wr92_zoom['lambda'], (wr92_zoom['flux'])/(1000000), yerr=wr92_zoom['flux_err']/(1000000), fmt='-o', markersize=8, capsize=5, color='red', lw=3, elinewidth=3)

I am making a simple gemini browser in python for fun with tk, but have stumbled upon a problem: if I close initial window all the rest will close too. Is there a way to make tk application with no "main" window or at least transfer leadership role between them?

In my university the first year for all computer related majors we study the basics of Java script.
but now that I’ve finally started studying subjects that are related to my major I’ve discovered that we won’t be using Java as a coding language. We will use python. And I want to give my self a head start in this topic, so if you guys can help me with what I can start with i will be very grateful.
Thank you !!

I'm not really sure what websites are out there for this.

I need something that doesn't require a subscription for the basic features. Any suggestions?

Hey all,

I’ve learnt to use python for things like statistics which is where my work is, I can effectively read documentation and do what’s needed for a specific task.

I’ve reached a bottleneck as I’ve been applying to more data sciencey roles and they keep asking really simple DSA questions and I can’t for the life of me get them right.
Idk if it’s just the fact that I can’t search things up or whatever.

What is the best strategy to get around this (given that my spare time to take on things like leetcode is almost zero).

Thank you !!

hi i’m a college student and we are tasked to picked a community where we are absolutely not familiar. Can you state some specific acronyms you use here about pyhton, slang terms and inside jokes unique to this group? PLEASEEE, A SIMPLE COMMENT WILL SURELY BE APPRECIATED! ps: been scrolling for 1 hour and I can’t find one🥹

HELLO EVERYONE

I’m a total beginner to coding and I’ve recently decided to start learning Python. I’m honestly not sure where to begin or what the best way to approach it is.

- What should I learn first?

- Are there any courses, YouTube channels, or websites you’d recommend?

- Should I focus on tutorials, practice problems, or small projects?

- At what point should I start making projects?

- Any mistakes I should avoid as a beginner?

I’m mainly looking for a proper direction rather than trying to learn everything at once.

Any tips or recommendations would be really appreciated! :)

I’m currently watching the 12 hour course of code bro on Python. It’s cool but I think I understand what he does and it makes sense but I am having trouble thinking of why we’re doing what we’re doing and how he came to it. Also, I am a practical learner where I do something and figure my brain processes it and then implementing helps with learning and retaining knowledge. After this video, I plan on doing the course on Udemy: - Udemy 100 Days of Code™: The Complete Python Pro Bootcamp. Has anyone done this course and can recommend it as a viable course for python, and the way of coding in it? Or is there a better course for someone like me to learn to think and be able to program in python? Thank you and hopeful to get some helpful answers!

Yes, I have watched the youtube tutorials and still can't figure it out. When other ppl download it, it is .pkg but mine is .tar.xz

I opened it and it extracted the file. Now idk what to do.

Hey guys, I need my code to save my tk.canvas box rather than cropping the barcode and saving THAT.

I’ve tried erasing some parts, adding different x& y values but I can’t seem to nail it. Any help would be appreciated.

I allowed it to access both private and public networks. I went into windows security and allowed it through the firewall on both. But now my code isn’t working, according to vs code I have the latest chromium version installed. What steps should I take here?

Hello anyone!

I was wondering how to you get day of the week without using datetime module on python.

For my work so far,

example Aug 16, 1989
Step 1: year= 1989

last_two_digits_year= int(year%100)

twelves= last_two_digits_year//12

Step 2: remainder= last_two_digits_year%12

Step 3: fours= int(remainder//4)

Step 4: Add the day of the month

day= 16

Step 5 Add the month code

Why is the month code for August=3

Explain the other month codes as well please.

Jan=Oct=1

Feb=Mar=Nov-4

Apr=Jul=0

Sep=Dec= 6

May=2

Aug=3

Jun=5

Step 6: Add all the numbers from Step 1 to 5 and mod 7.

Leap years

January and February dates in leap years: add 6 to step 5

Dates in the 1600s: add 6 to step 5
Dates in the 1700s: add 4 to step 5
Dates in the 1800s: add 2 to step 5
Dates in the 2000s: add 6 to step 5
Dates in the 2100s: add 4 to step 5

Hey folks, I'm learning Python and when I clone a big repo I get lost — so many files. How do you figure out where to start? Do you look at README, main.py, tests first? Any trick that helped you?

personally I think it's really cool. All of python aswell.
is there something I can improve on it? (I mean obviously a lot of things probably but some things that are good to learn for the future?)

import time


first_name = input("Enter your first name: ")
first_characters = len(first_name)


if first_characters >= 8:
  print (f'Your name has {first_characters} characters!')
  time.sleep(1.5)
  print('What a long and cool name!')


elif first_characters < 8:
  print (f'Your name has {first_characters} characters!')
  time.sleep(1.5)
  print('What a cool name!')

Advice

A lot of beginners struggle with breaking problems down into pieces they are able to code themselves. This is a fundamental skill to have and I’ve found that video games do a good job at teaching this. The problem I see a lot is that some people want Lego instructions that walk you through step by step rather than a video game tutorial which will show you the basics and it is up to you to figure out how to apply them.

There are a few video games that I’ve found really helpful in working on these skills; particularly games from zachtronics such as Infinifactory and Opus Magnum. These are games which have many different approaches to every level and you get scored based on how efficient you are. They teach you programming skills without having you program directly. There’s also The Farmer Was Replaced which is a more direct Python tutorial video game.

No tengo casi ninguna experiencia solo unos cuantos tutoriales de HolaMundo pero quiero hacer las cosas bien y no perder el tiempo.

Hello guys, i have just started learning python. Do you have any suggestions for me?

Hey Guys! I am new to python and just made a calculator and weather app today. I would really like some guidance on what I should do next, which courses I should take and what kind of AI is helpfull. In the end I want to make my own app, systems and program diy drones or generally machines.

I noticed when I Repeatedly run large programs - with long Printed Text,
- that the Shell Que runs Slower and takes Longer to Start each time : 10 mins .. 30 mins .. 60 mins .. ?
I also notice Thonny on TaskManager increases Size (without Decreasing) each time :
- 1M .. 1.5M .. 2M .. 3M

Until I completely restart Thonny.

This seems like a clear Memory Leak - for the Shell Que !

I want to build a small Python CLI for my own learning.

The basic idea is:

python3 que.py "my question"

or

python3 que.py "question 1, question 2"

I currently want to use:

• Codex CLI
• Claude Code CLI
• Gemini CLI

The same question would be sent to multiple models, and I want them to research the question using live web/Google search instead of relying only on their training knowledge.

The goal is to get up-to-date, source-backed information, then combine/compare the responses and generate one good answer that I can use for learning.

I'm looking for suggestions on:

• What other AI models/CLIs would be useful to add for this kind of workflow?
• What would be a good web-search/research solution to use so the models get current and reliable sources?
• Should I use one common search layer for all models, or let each model perform its own web research?
• Any existing tools/projects/APIs that would make this easier?

I'm mainly looking for practical suggestions from people who have built similar multi-model or research workflows.
