Slicing for substrings

In many situations, you might need a particular portion of strings such as the first three characters of the string. Python's subscript operator uses slicing. In slicing, colon : is used. An integer value will appear on either side of the colon. Refer to the following example:

>>> name[0:3]
'The'
>>> name[:6]
'The Av'
>>> name[4:]
'Avengers'
>>> name[5:9]
'veng'
>>>

>>> name[::2]
'TeAegr'
>>>

Refer to the following diagram to clear your remaining doubts:
