Selection - Python

What is Selection

Selection is a key construct that exists in any programming language, and each language has a specific implementation but they are all relatively the same.The other key constructions are sequence (ie program runs in order) and iteration (loops).

If Statement in Python

Use the command ‘if’ followed by a condition & the colon ‘:’, The condition should equate to true or false. Instead of using brackets, in python you indent the code to run if true. Each line with the same indent will be run if true. The else can also be used followed by a colon ‘:’ and again the code to run in the else should be indented:

if true:
    line 1
    line 2
else:
    line 3
    line 4
