Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

```str="+++Welcome python+++"
str.strip()

print(str)```

Output:

`+++Welcome python+++`
