for else

for/else clause could be useful when you go through iterable for searching purpose.

• If break isn’t called inside for loop, else caluse will be execute.

• If break is called inside for loop, skip else clause.

Example:

ls = [1, 2, 3]

for i in ls:
  print(i)
else:
  print("Excute else")

# Output:
1
2
3
Excute else

Example:

for i in ls:
  print(i)
  if i == 3:
    print("Execute break")
    break
else:
  print("Excute else")

# Output:
1
2
3
Execute break
