We can represent a set of code a specified number of times through a loop, then we 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.

Example -

Using the range() function
for x in range(5):
    print(x)

Output

Note:

The range(5) is not the values of 0 to 5, but the values 0 to 4.

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, 5), which means values from 2 to 5 (but not including 5):

Example -

Using the start parameter
for x in range(2,5):
     print(x)

Output

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(3, 40, 2):

Example -

Increment the sequence with 2 (default is 1):
for x in range(3,20,2):
    print(x)

Output
