Hobs <hobsonl...@gmail.com> added the comment:
It is a limitation of f-strings, though. We're not allowed to use
backslashes within the f-string expression in curly braces. So to do what
you want you have to create another variable containing the quote character:
```
>>> blah = '"hi"'
>>> blah
'"hi"'
>>> q = '"'
>>> f'{blah.strip(q)}'
'hi'
```
