range() Function

---

This  function  is  a  unique  function  that  allows  a  programmer  to  easily  generate  a  sequence  of
numbers. In the example below, we can print a range of numbers from 6 to 15.
for scores in range(6, 15):
print(scores)
In as much as the code seems like printing the numbers from 6 to 15, however, it doesn’t print the
number 15. Our output will be as follow:
6
7
8
9
10
11
12
13
14
In our example below, the range() function prints only the numbers from 6 to 15. Well, this is the
product  of  the  off-by-one  behavior,  which  exists  in  most  programming  languages.  The  function
makes  the  interpreted  to  start  the  counting  process  at  the  initial  number  but  stops  at  the  second
number before reaching the number indicated. However, if you wanted to print out the number 15,
that means you have to extend the stopping point by one. In this case, it is 16. Therefore, your code
will be as follows:
for scores in range(6, 16):
print(scores)
Moreover, your output will be:
6
7
8
9
10
11
12
13
14

15
If your output doesn’t match what you wanted when using the range() function, then you have to
adjust the ending value by 1.
