- Here end is a parameter, It indicates the value search where to end. This parameter is also optional.
Example of find() Method: Using three Parameter
#Example 2

'''Searching will start from 6th indexing
and end up to 20th indexing.'''
print(text.find("p",6,20))
#Output: 12Find the position of the particular word with find() Method
