String Replace Method
The str.replace(old, new, max) method is used to replace the substring old with the string new for a total of max times. This method returns a new copy of the string with the replacement. The original string str is unchanged.
Examples
- Replace all occurrences of
"is"with"WAS"
string = "This is nice. This is good."
newString = string.replace("is","WAS")
print(newString)
Output:
ThWAS WAS nice. ThWAS WAS good.
As you can see above, the "is" in This is also replaced with Was.
To prevent this we can use
string = "This is nice. This is good."
newString = string.replace(" is "," WAS ")
print(newString)
Now the output becomes:
This WAS nice. This WAS good.
Here the "is" between whitespaces gets changed to "Was"
- Replace the first 2 occurrences of
"is"with"WAS"
string = "This is nice. This is good."
newString = string.replace("is","WAS", 2)
print(newString)
Output:
ThWAS WAS nice. This is good.
