Create A List



In [1]:

    
# Create a list:
armies = ['Red Army', 'Blue Army', 'Green Army']

Breaking Out Of A For Loop



In [2]:

    
for army in armies:
    print(army)
    if army == 'Blue Army':
        print('Blue Army Found! Stopping.')
        break









    



Red Army
Blue Army
Blue Army Found! Stopping.

Notice that the loop stopped after the conditional if statement was satisfied.

Exiting If Loop Completed

A loop will exit when completed, but using an else statement we can add an action at the conclusion of the loop if it hasn't been exited earlier.



In [3]:

    
for army in armies:
    print(army)
    if army == 'Orange Army':
        break
else:
    print('Looped Through The Whole List, No Orange Army Found')









    



Red Army
Blue Army
Green Army
Looped Through The Whole List, No Orange Army Found
