Python Homepage

This is the Python home page where I will tell you the basics, to skip to the coding and writing of programmes click here,

Variables, variables are what all of the other code revolves around, they are where all the data is stored so if you wanted to do a maths programme that did the addition of 2+2 you would store the answer in a variable which you name. Variables can be named anything you type.

EG. 2 + 2 = a. 

this would store the answer 4 into the variable a.

print() = this is a handy function that lets you output data to the console, in other words it lets you see the data on the screen.

EG. print("hello world")

EG. print(10)

+, -, *, / = these signs let you add, subtract, multiply and divide.

input() = this lets the user input data using a keyboard, however the data has to be assigned to a variable in order to store that data the users can be told what to input by the programmer writing what he wants the users to type.

EG. data = input("what's you name? ")

Using what we have learned on this page we can now write a very simple programme that says hello and asks for your name and does simple addition.

print("hello world")

data = input("what is your name")

addition = 2 + 2

print(addition)

for a more efficient code, which is the goal for programmers, we can combine some of the code and write:

e = input("hello world, what is you name? ")

print(2 + 2)
