# 30. For Loop In Python range()

"""
# To loop through a set of code a specified number of times, we can use the range() function,
    The range() function returns a sequence of numbers, starting from 0 by default, and
    increments by 1 (by default), and ends at a specified number.
# The range() function defaults to 0 as a starting value, however it is possible to specify the
    starting value by adding a parameter: range(2, 6), which means values from 2 to 6
    (but not including 6)
# The range() function defaults to increment the sequence by 1, however it is possible to
    specify the increment value by adding a third parameter: range(2, 30, 3)
# The else keyword in a for loop specifies a block of code to be executed
    when the loop is finished
