It asks for a substring as a parameter, which the function then locates and replaces. In data cleaning, this replace() method is frequently employed.

Since strings cannot be changed, the method instead changes characters on a duplicate of a original string.

Hence, if you intend to reuse the new string, be sure to keep it safe.

The series of Unicode characters is stored in a string, an immutable data type.

Python provides a number of methods for replacing a string. Using Python's built-in method string is one of the most popular approaches. replace().

An immutable data type known as a String maintains a collection of Unicode characters.

As there is no Python character data type, any number of characters are treated as strings.

Python's re.sub() function and.replace() technique are frequently used to tidy up text by eliminating or substituting strings or substrings.

Step By Step Guide On How To Replace A Character In A String In Python :-

string = 'talkerscodeexample'
position = 7
new_character = 'S'
string = string[:position] + new_character + string[position+1:]
print(string)
  1. We start by producing a string called a talkerscode example. One of the most often utilized data types in computer languages is the string one. Python enables the creation of strings with just the use of quotations (single & double quotes).
