Performing repetitive tasks  

using the for loop

Sometimes you need to perform a task more than one time. You use the 

for

 loop 

statement when you need to perform a task a specific number of times. The 

for

 

loop has a definite beginning and a definite end. The number of times that this 

loop executes depends on the number of elements in the variable you provide. To 

see how this works, open a copy of IPython and type the following code:

def DisplayMulti(*VarArgs):

    for Arg in VarArgs:

        if Arg.upper() == 'CONT':

            continue

            print('Continue Argument: ' 

+ Arg)

        elif Arg.upper() == 'BREAK':

            break

            print('Break Argument: ' 

+ Arg)

        print('Good Argument: ' 

+ Arg)

In this case, the 

for

 loop attempts to process each element in 

VarArgs

. Notice that 

there is a nested 

if

 statement in the loop and it tests for two ending conditions.
