Troubleshooting TypeError: 'str' Object Doesn't Support Item Assignment

When attempting to access or modify individual characters of a string using item assignment, Python may raise a "TypeError: 'str' object does not support item assignment" error. To resolve this error, several methods can be employed.

One approach is to convert the string into a list, allow individual character manipulation, and then convert it back to a string. This is demonstrated below:

s1 = "Hello World"
list1 = list(s1)  # Convert string to list
list1[5] = 'u'  # Modify character at index 5
s1 = ''.join(list1)  # Convert list back to string

This approach allows you to make character-level changes while maintaining the integrity of the string.

Alternatively, you can utilize string formatting to insert characters at specific positions:

s1 = "Hello World"
j = 5
s2 = s1[:j]   'u'   s1[j   1:]  # Insert 'u' at index 5
