How to download a file from ftp in python?

Question

Python

I took the code for a test, but the part that is responsible for downloading the file
writes:
with open(src, 'wb') as f:
PermissionError: [Errno 13] Permission denied: 'C:/Users/qubers/PycharmProjects'
Here is the code itself:

src = "C:/Users/qubers/PycharmProjects"
with open(src, 'wb') as f:
    ftp.retrbinary('RETR ' + 'offsets.cfg', f.write)

Answer 1

what is written in the error?
How would it sound in Russian?
