For Loop with else:

In python, a for loop can have an optional else block as well.
The else block is executed if the items in the sequence used in for loop exhausts.
Syntax:
for var in sequence:
statement(s)

range() function in Python:

range() function has 2 prototype:
1. range(stop)
always starts from 0 to (stop-1).
2. range(start, stop, step)
We can also define the start, stop and step size. Step size defaults to 1 if not provided.
range(1,10) will generate numbers from 1 to 9 (10 numbers).

NOTE: range() function only accepts integer value
