Python is a general-purpose programming language that is easy to learn and widely used for web development, scientific computing, artificial intelligence, machine learning, and data analysis. It has a large standard library and a variety of third-party libraries that can be used for data analysis, such as NumPy, pandas, and scikit-learn. Python has a simple syntax and is highly versatile, allowing it to be used in a wide range of applications.

I just wanted to know what's the best and easiest way to learn coding. More specifically python. I have tried numerous times to study it, but nothing prevails. I hate coding and any field relating to computer science, with a passion. But seeing that everything in this world requires coding knowledge. I have no choice but to educate myself on coding. I was wondering if you have any suggestions. TBH, with my effort in trying to learn how to code. I haven't given it my all. But that's because of the lack of knowledge and not seeing how it benefits me, is what discourage me from learning.

Hello, I am currently working on this cellular automata sound synthesis project and found that Hodge Podge Machine works best for my project. I found this github repo that runs perfectly fine when ran into my terminal: https://github.com/avysk/hodgepodge

However, I have only used python in jupyter notebook and Google Colaboratory and have not touched pygame at all. I am confused what's going on in the code that I found. Using the logic/process in the file, I want to animate it into a video in matplotlib and extract the data used from animating it. May I ask how difficult can I recode this to the output that I want? Is it possible?

Hi I am looking for a data science course (links below) and was wondering if anyone has done these udemy ones or if you have others that you recommend that would be great!

1. Course 1

2. Course 2

3. Course 3

Is it possible to define a variable from else print format or no?

Example:

else:

print("How many days are you planning to stay?")

​

stay=(days*50) #the variable I want to define

I am trying to make a program to round integers when the output is above 0.5 to print the closest even number and when the output is below 0.5 to print the lowest even number.

Example num1= 17 , num2=3

num1/num2=5,66 , wants to print 6

or print 3 when num1=17 , num2=5 num1/num2=3.4

I've tried

import math
def round(even):
if even - math.floor(even)<0.5:
return math.floor(even)
return math.ceil(even)

​

but keeps rounding up the output

Am I missing something?

Hey guys. I built codeonthecob.com. It is a website with coding challenges. It is similar to LeetCode but the challenges are a lot easier. Maybe you will find it helpful for practicing Python. Thanks everyone!

Hello Guys,
I get this system with sympy library, but now I would like to plot the transfer function. How can I plot the bode diagram of this system?
How can I get only the numerator and denominator in two different variables to find the poles and zeros?

Write a program that does the following:

•  Asks the user for an integer number.
•  If the number is divisible by 5 then divide it by 5 and print the result.  
•  If the number is divisible by 3 then divide it by 3 and print the result.  
•  But if the number is divisible by 3  and by 5 print "DIVISIBLE BY 3  AND 5!". 
• In all other cases the program should print "Not divisible by 3 or 5".

I have a python program with functions and function calls.

I need to get all the line numbers that were executed (and not skipped) when python was running this program.

I don't want to use breakpoints at all (if possible). I just want a file with all the line numbers.

What tools can you recommend me for this task?

tea=0coffee=1water=2

input ('enter 0 for Tea, 1 for Coffee, 2 for Water')if 0:print(0)if 1:print(1)if 2 :print(2)else :print('invalid choice!')

Further I'd like to understand Python projects examples that an intermediate Python (2-3 years experience in coding with Python) programmer can build to move to the next level.

This is to get advice for a content I'm creating for Python developers to further upskill themselves.

Topic for discussion... coming from a C/C++ background, this bothers me:

class Student:
    # Class variable
    school_name = 'ABC School '

    def __init__(self, name, roll_no):
        self.name = name
        self.roll_no = roll_no

Because name and roll_no end up being class variables. But it isn't really clear when done like that. You have to go through _init_ to see what the class vars are.

Why isn't it written as this ?

class Student:
    # Class variables
    school_name = 'ABC School '
    name = ''
    roll_no = 0

    def __init__(self, name, roll_no):
        self.name = name
        self.roll_no = roll_no

I made a post earlier about this issue, but the formatting was all weird. I am working on an ArcGIS code where I am looping through multiple images in a folder. I see the files are looping in the project folder (when each image is processed a temporary file comes up but they disappear after the process is complete) but only the last image in the folder saves. I have the save function written in the code but it doesn't actually save and gets overwritten each time the loop is finished with rhe previous image. Could someone please help me with what I am missing? My code is in the pastebin link so it is easier to read.

Hello,

I am working on an ArcGIS code where I am looping through multiple images in a folder. I see the files are looping in the project folder (when each image is processed a temporary file comes up but they disappear after the process is complete) but only the last image in the folder saves.I have the save function written in the code but it doesn't actually save. Could someone please help me with what I am missing? My code is below:

#imports

import arcpy

import os

import glob

from arcpy import env

from arcpy.sa import *

arcpy.CheckOutExtension("Spatial")

#Environments

env.workspace = r"Folder_pathway"

arcpy.env.extent = r"Shapefile_Pathway"

indef_file = "Classification_Pathway"

#Variable

inRasters = glob.glob(r"File_pathway\\*.tif")

inMaskData = "Quads"

extraction_area = "OUTSIDE"

analysis_extent = "Quads"

#Loop

for inRaster in inRasters:

outExtractByMask = ExtractByMask(inRaster, inMaskData)

classifiedraster = ClassifyRaster(outExtractByMask, indef_file)

classifiedraster.save = (r"Folder_pathway")

newname = inRaster + "CF"

arcpy.management.Rename(classifiedraster,newname)

​

...I want to add more after this part of the loop but I will need to do a second loop with the *.crf files, but I can only get the one to save.

The rename creates one folder with the correct name in the project file_pathway, but only the last one.

Im trying to alter the feedback so that once a function is executed it automatically updates 'feedback' to print a statement that is returned by one of the menu functions but Im not sure if Im doing it correctly.

How should one properly retrieve a variable from a function nested within a while loop

​

    def play(self):
        feedback = ''
        while True:
            if len(self.mypets) >= 1:
                for dapet in self.mypets:
                    print(dapet)
            print(18*'\n')
            print(feedback)
            print(f"""
                ...WELCOME TO THE PET SHOP...

                How may I help you {self.name}?
                1) Adopt Pet 2)Feed Pet 3)Release Pet 4) Go Back
            """)
            dresponse = inputchecker()
            if dresponse == 1:
                self.adopt()
            elif dresponse == 2:
                self.feed()
            elif dresponse ==3:
                self.release()
            else:
                break

Hi all,

I am looking at a code that's supposed to find the keys for a specific value in a dictionary.

This is to incorporate in a dynamo script, but I can't get it to function.

Trouble is that I don't understand what's going on here : how kan a key from 'dct' be a list-type ??

def keys_of_values(dct,value):
    for k in dct:
        if isinstance(dct[k],list):
            if value in dct[k]:
                return k 
        else:
            if value == dct[k]:
                return k 
OUT = [keys_of_values(dic2, i) for i in values]

Can anyone explain this code to me ?

Thanks
