python loop if true go back to previous loop code example
Example 1: python loop back to start
def main(): #defines the area in indents that will be triggered with main()#
print('hi')
yn = input('Wanna loop back to the start? ')
if yn = 'yes':
main() #loops back to where we defined main#
main() #This starts the main loop, without this, main would just be defined but not run#
Example 2: python exit loop iteration
alphabet = ['a' , 'b' , 'c' , 'd' ]
for letter in alphabet:
if letter == 'b' :
continue
#continues to next iteration
print( letter )
for letter in alphabet:
if letter == 'b' :
break
#terminates current loop
print( letter )
for letter in alphabet:
if letter == 'b' :
pass
#does nothing
print( letter )
