PYTHON FOR LOOPS

The most powerful thing about computers is that they can repeat things over and over very quickly. There are several ways to repeat things in Python, the most common of which is the for loop.

Example 1 .

The following program will print Godliness, Focus and Excellence  ten times:

for i in range(10):

            print('Godliness, Focus, and Excellence')

The structure of a for loop is as follows:

 for variable name in range( number of times to repeat ):

                    statements to be repeated

The syntax is important here. The word for must be in lowercase, the first line must end with a colon, and the statements to be repeated must be indented. Indentation is used to tell Python which statements will be repeated.

 

Example 2 .

 The program below asks the user for a number and prints its square, then asks for another number and prints its square, etc. It does this three times and then prints that the loop is done.

 for i in range(3): num = eval(input('Enter a number: '))

 print ('The square of your number is', num*num)

print('The loop is now done.')
