How To Use Python

To use Python, you can either download IDLE, a Python shell, or you can use an online website. The website I use is Trinket, which I would recommend.

If you're using an app, to create a program you'll have to find "New Program" in the menus to create a program.

If you're using Trinket, you'll have to create an account, then select your username, then select New Trinket, then select Python to create a new Python program.

You may need to look online to learn how to operate your app or website.

Here's an example of a code box:

print("Here's some code.")

if a == 2:

print("Here's more code.") # Runs if a == 2 is True.

See the bold text? Did you notice that it's all after the # symbol? In Python, anything after a # is ignored. This is used to add comments. In this website, comments are always shown in bold to help you recognize them.

Sometimes you'll see a comment after a print() command. The comment is just showing what Python will output. Ex:

print("Python's as easy as %s!" %(123)) # Python's as easy as 123!

Sometimes you'll also see italic numbers before each line. These are line numbers, which you should NOT type in.

After reading through this webpage, you'll even be able to understand crazy programs like this:

from turtle import *

import time as t

class New(Pen):

def square(self,size = 10):

for i in range(0,3):

self.forward(size)

self.left(90)

t.sleep(1)

turtle = New()

turtle.color("purple")

turtle.fillcolor("blue")

turtle.begin_fill()

turtle.square(50)

turtle.end_fill()
