remove powered number from string in python

Question

I want to remove the power of number from string. how can I do that? for example the number is:

1¹

I know its Unicode is :1\u2071

I find this:

 text = re.sub("(\([^)]*\)|\w)\^(\([^)]*\)|\w)", ' ', text)

but not works.

Answer 1

What you have found seems to match expressions like x^y, where the superscript is expressed with the ^ character.

However, the strings you are trying to match uses actual superscript characters, which are limited to these:

²³¹⁰ⁱ⁴⁵⁶⁷⁸⁹⁺⁻⁼⁽⁾ⁿ

Therefore, you could just create a character class with those:

\d+[²³¹⁰ⁱ⁴⁵⁶⁷⁸⁹⁺⁻⁼⁽⁾ⁿ]+

Demo

Answer 2

import re
test = '1¹'
text_n = re.sub("(¹)", ' ', test)
print (text_n)
