The replace method
The replace method searches and replaces a string. In the first parameter of the method, we specify the substring we want to replace. In the second parameter, we specify what we want to replace it with. In the third optional parameter, you can specify the number of times the substring will be replaced.
Syntax
string.replace(what we change, what we change, [number of replacements])
Example
Let's replace all the characters 'a' with !:
txt = 'abacdea'
print(txt.replace('a', '!'))
Result of code execution:
'!b!cde!'
Example
Now let's set the number of replacements:
txt = 'abacdea'
print(txt.replace('a', '!', 2))
Result of code execution:
'!b!cdea'
