The most useful python modules for beginners
Not long ago, I was a beginner to python. I was eager to make games, but had a hard time finding how to create certain elements of the game, such as choosing a random number or shuffling a list. That is when I discovered that there was no special tutorial in most places to teach you how to do these simple things. So thus, a tutorial by me (obviously) to help in things that don't have special tutorials.
(These are things I found useful)
CHOOSING A RANDOM NUMBER
To do this, at the top of your code, type in
import random. This is what you call a module. Basically, a module is a bunch of functions that you can import to use in your code.
For example, if you want to make a variable called
x, and assign in to a random number, you would do the following:
This is assigning a random integer or number between 0 and 10 to
So to create a random integer, first
import random, then
randomvar=random.randint(start point, end point)
So what ever random number you want, just remember the
CHOOSING A RANDOM ITEM FROM A LIST
To do this, instead of typing
random.randint(), you type
For example, if I had a list like this:
And I wanted to assign assign a variable called
y to a random item from the
fruit list, I would type the following:
SHUFFLING A LIST
If I wanted to shuffle
fruit, just do the following:
WAITING A FEW SECONDS
import time. Now if we want to wait between two
In this case, it will print 'hi', wait 1 second, then print 'bye'.
PS- I made it wait only 1 second, but it can sleep for as long as you want by entering a different number in the
CLEARING THE TERMINAL
import os then type
os.system('clear'). This will clear the terminal.
COLOURS IN PYTHON
Thanks to @Bookie0 for reminding me to add colours
I wanted to to do this a lot when I started out with python, but I couldn't find anywhere that told me how to print coloured text. But after a little snooping around in other people's repls when posted, figured it out.
This is a list of colour values in python (copy and paste them into your code). To do an example, let's
print('I am blue text') in blue (obviously). To
print(Blue,'I am blue text')
We can use any colour or effect we want, from the above list.
Below are some additional effects and ways you can
Feel free to experiment with the colours and different types of text decoration.
Hope you liked it :)

The random choice one would be useful in my past visual novel, because the enemy could only attack, even though three actions were possible. If I create a list with the possible actions, it can be chosen randomly, making him either attack, attack strongly or guard, which were the three possible actions.
Alternatively, I could use randint and just code the actions the enemy could use as 1, 2 and 3, rather than making a list for the code to choose from... No idea why I didn't think about this before...
Either way, thanks for the tutorial. Much appreciated.
Hey! This is very useful, and I will admit I didn't read all of it (, because I want to get back to programming) but, I have a problem where for example I do a 'Whats your name' type of thing and I get the output "<built-in function input>". Can somebody please help?
Hello! I'm very new to python so let me know if this is wrong! I wanted to only use italic on only a select sentence or word in my print statements, but was having a hard time finding a way to make it not do the entire sentence or the back end of the statement when I tried to put it into the middle. It turns out I had to put something in that told the code there to end, and this was just changing the number before m to 0! I tried it out on most of the colors and all of the effects and it seemed to work! Feedback is appreciated!
you might want to include the sys library for creating command line argument applications. This makes it easy to automate processes. If you want me to tell you about it in a private repl then i will
