Procedures in python

Procedures are computer program creates that let us capture common patterns of computation by:

• Grouping together sequences of statements

• Abstracting away from particular data values on which they perform.

Here is a procedure de?nition,17 and then its use:

def square(x):

return x * x

>>> square(6)

36

>>> square(2 - square(2))

4

We will work  through, in detail, what  happens when  the interpreter computes a procedure de?n­ition, and then the application of that method.
