A for loop can have an optional else block as well. The else part is executed if the items in the sequence used in for loop exhausts.
The break keyword can be used to stop a for loop. In such cases, the else part is ignored.
Hence, a for loop's else part runs if no break occurs.
Here is an example to illustrate this.
digits = [0, 1, 5]
for i in digits:
print(i)
else:
print("No items left.")
Here, the for loop prints items of the list until the loop exhausts. When the for loop exhausts, it executes the block of code in the else and prints No items left.
This for...else statement can be used with the break keyword to run the else block only when the break keyword was not executed.
