The Start_val represents the initial value, and the End_val represents the final value. The Step_val
represents the value by which the counter variable is incremented or decremented. The Start_val
and the Step_val are optional values but the End_val is compulsory. The default value for the Start_
val is 0 and Step_val is 1. The counter variable begins with the initial value, increases the value by the
step value until it reaches a value 1 less than the value specified in the range function.

Consider the following examples of range function:
• The statement range(5) will create a list of numbers from 0 to 4, i.e., 0, 1, 2, 3, 4
• The statement range (1,10) will create a list of numbers from 1 to 9, i.e., 1, 2, 3, 4, 5, 6, 7, 8, 9

• The statement range (1, 10, 2) will create a list of numbers from 1 to 9 with a gap of 2 between
two consecutive numbers, i.e., 1, 3, 5, 7, 9
