在 python 中补充 maketrans 以进行翻译

Question

For translating tr in perl to python, I am using string.maketrans and str.translate . However, for the perl expression:

$val =~ tr/\0-\377//c

The user is asking for the complement of the translation. How I generate python code for that?

Answer 1

I assume you want to delete characters not int the range of ordinal values [0-255], then you could simply do

val = "".join([ch for ch in val if 0o000 <= ord(ch)<= 0o377])
