35 - For loop with else

Python - else in Loop

  • Python allows the else keyword to be used with the for and while loops too. The else block appears after the body of the loop.
  • The program exits the loop only after the else block is executed.
  • The statements in the else block will be executed after all iterations are completed.

Syntax

for counter in sequence:
    #Statements inside for loop block
else:
    #Statements inside else block

Example:

for x in range(5):
    print (f"iteration for {x+1} in for loop")
else:
    print ("else block in loop")
print ("Out of loop")

Output:

iteration no 1 in for loop
iteration no 2 in for loop
iteration no 3 in for loop
iteration no 4 in for loop
iteration no 5 in for loop
else block in loop
Out of loop

Notes:-

  • After Breaking loop, the else will not be printed.

Example:-

	for i in []: # creating empty list
	    print('nope')
	    break
	else:
	    print('this will not be printed as loop is broken')

Output:

      # as loop is broken
Else will be printed only if loop's condition is not met, like in the end of the loop when conditions are met and loop is finished.....
