 ### The Range Function
 
-The _range()_ function is used to loop through a set of code a certain number of times. The _range(start,end, step)_ takes three parameters: starting, ending and increment. 
-  start: integer starting from which the sequence of integers is to be returned
-  stop: integer before which the sequence of integers is to be returned.
-         The range of integers end at stop – 1.
-  step: integer value which determines the increment between each integer in the sequence
-By default it starts from 0 and the increment is 1. The range sequence needs at least 1 argument (end).

 Creating sequences using range
 
 ```py
-lst = list(range(11)) 
+lst = list(range(11))
 print(lst) # [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
 st = set(range(1, 11))    # 2 arguments indicate start and end of the sequence, step set to default 1
