Else with loop in python

 

Else With Loop

The else clause executes after the loop completes normally. This means that the loop did not encounter a break statement. यदि loop अपने आप terminate हो रहा रहा है या एक बार भी नहीं चल रहा है तो else चलेगा ओर यदि break से terminate होता है तो loop नहीं चलेगा।

Else in For Loop

The else keyword in a for loop specifies a block of code to be executed when the loop is finished:

Example

Print all numbers from 0 to 5, and print a message when the loop has ended:

for x in range(6):
  print(x)
else:
  print("Finally finished!")

Note: The else block will NOT be executed if the loop is stopped by a break statement.

Example

Break the loop when x is 3, and see what happens with the else block:

for x in range(6):
  if x == 3: break
  print(x)
else:
  print("Finally finished!")

Else in While Loop

With the else statement we can run a block of code once when the condition no longer is true:

Example

Print a message once the condition is false:

i = 1
while i < 6:
  print(i)
  i += 1
else:
  print("i is no longer less than 6")

Example

i = 1
while i < 6:
  print(i)

  if i == 3: break
  i += 1
else:
  print("i is no longer less than 6")
