Python - replace all occurrences of string

In this article, we would like to show you how to replace all occurrences of string in Python.

Quick solution:

xxxxxxxxxx

text = "ABC ABC ABC"

replacement = "X"

result = text.replace("C", replacement)

​

print(result)  # ABX ABX ABX

In this example, we use String replace() method to replace all occurrences of the "C" letter in the text string.

xxxxxxxxxx

text = "ABC ABC ABC"

replacement = "X"

result = text.replace("C", replacement)

​

print(result)  # ABX ABX ABX

Output:

xxxxxxxxxx

ABX ABX ABX

Note:

Optionally you can add the third argument that specifies how many occurrences of the old value you want to replace. By default the replace() method replaces all occurrences.

In this example, we use String replace() method with the third (count) argument to replace 2 occurrences of the "C" letter in the text string.

xxxxxxxxxx

text = "ABC ABC ABC"

replacement = "X"

count = 2

result = text.replace("C", replacement, count)

​

print(result)  # ABX ABX ABC

Output:

xxxxxxxxxx

ABX ABX ABC
