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:

String positive and negative slicing

Note

If you want to print a reverse of the given string str1, then use str1[::-1]

To find the length of a string, you can use the len() function:

>>> len(name)
12
>>> 

Now, let's see some useful string methods.
