Python's str.replace(~) method returns a new copy of the string with all occurrences of the old substring replaced by the new substring.

Parameters

1. old | string

The substring to be replaced by new.

2. new | string

The substring to replace old substring with.

3. count | number | optional

The number of occurrences of the old substring to replace. Defaults to all occurrences.

Return value

Returns a new copy of the string with all occurrences of the old substring replaced by the new substring.

If count argument is provided, only the first count occurrences will be replaced.

Examples

Basic usage

To replace all occurrences of "Hi" with "Hello":

x = "Hi Hi Hi!"
x.replace('Hi', 'Hello')
'Hello Hello Hello!'

We can see that all occurrences of 'Hi' are replaced by 'Hello' in the returned string.

Count parameter

To replace only the first two occurrences of 'Hi':

y = "Hi Hi Hi!"
y.replace('Hi', 'Hello', 2)
'Hello Hello Hi!'

We can see that only the first two occurrences of 'Hi' are replaced by 'Hello' in the returned string.
