Python string replace() method example

In this source code example, we will demonstrate how to use the Python string replace() method to replace some or all occurrences of a substring with a new substring.

Use the Python string replace() method to return a copy of a string with some or all occurrences of a substring replaced by a new substring.

Python string replace() method example

The following example uses the string replace() method to replace all occurrences of the substring 'C' with the new substring 'Python':
s = 'C programming is a top programming language'
new_s = s.replace('C', 'Python')

print(s)
print(new_s)

s1 = 'C is a OOP language'
new_s1 = s1.replace('C', 'Python')

print(s1)
print(new_s1)

Output:

C programming is a top programming language
Python programming is a top programming language
C is a OOP language
Python is a OOP language
The following example uses the replace() method to replace the first occurrence of the substring:

s = 'Python Python source code examples'
new_s = s.replace('Python', 'The', 1)

print(s)
print(new_s)

Output:
