python removing specific non-ASCII characters from a string

Question

I have searched for a solution online but this question is different, since I don't want to remove all non-ASCII chars, just a specific part of them.

I have a line that looks like that:

"[x+]4 gur Id lú gal sik-kát ⌈ x x ⌉ [……………]"

I want to remove only these chars:

'…' , '⌉' , '⌈'

The text is from here.

I tried to solve it using replace but whenever I write one of these non-ASCII chars I'm getting the following error line:

SyntaxError: Non-ASCII character '\xe2' in file C:/-------.py on line --, but no encoding declared;

Thanks in advance.

Answer 1

'[x+]4 gur Id lú gal sik-kát ⌈ x x ⌉ [……………]'.encode().decode('ascii', errors='ignore')

out:

'[x+]4 gur Id l gal sik-kt  x x  []'

use encode to convert string to bytes, and decode it by ascii and igore the error.

I think you should use re.sub :

import re

text = "[x+]4 gur Id lú gal sik-kát ⌈ x x ⌉ [……………]"

re.sub('[…⌉⌈]', '', text)  # this will replace all the element in [] with ''

out:

'[x+]4 gur Id lú gal sik-kát  x x  []'

Answer 2

Use str.translate,

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import string

s = "[x+]4 gur Id lú gal sik-kát ⌈ x x ⌉ [……………]"
r = s.translate(None, '…⌉⌈')

print(r)
# [x+]4 gur Id lú gal sik-kát  x x  []
