Walrus operator in list comprehensions [Python 3.8.0]

from os import getcwd, listdir, rename
import re

[rename(f'{p}{n}', f"{p}{''.join([w[:3] if len(w) > 3 else w for w in re.split('[-_. ]', n)[:-1]])}.{n.split('.')[-1]}")
 for n in listdir(p := f"{getcwd()}\\{input('Folder: ')}\\")]

When I run this code, I'm getting:
  File "C:\Users\1\Desktop\sn.py", line 4
    [rename(f'{p}{n}',f"{p}{''.join([w[:3] if len(w)>3 else w for w in re.split('[-_. ]',n)[:-1]])}.{n.split('.')[-1]}") for n in listdir(p:=f"{getcwd()}\\{input('Folder: ')}\\")]
                                                                                                                                         ^
SyntaxError: assignment expression cannot be used in a comprehension iterable expression

Walrus operator in list comprehensions [Python 3.8.0]

We're not mind-readers, how do you expect us to know what you tried if you don't tell us?

The walrus operator works for me:

    >>> [spam for c in "hello world" if (spam:=c.upper()) in 'AEIOU']
    ['E', 'O', 'O']

    >>> [(spam:=x**2, spam+1) for x in range(5)]
    [(0, 1), (1, 2), (4, 5), (9, 10), (16, 17)]


What did you try, and what happened?
