python remove unknown text inside specific mark-CodePudding

I have this text text = "{\g1}Hello world!{\i6}" I want to remove the curly brackets and the text inside them without knowing what is inside the curly brackets, I know how to remove a specific text by using .replace("Hello", "Hi") (sorry for my English)

CodePudding user response：

You can use regular expressions to find & replace a particular pattern of characters.

In this case, a suitable regex pattern would be {\\.{2}}.

{ matches a "{" character
\\ matches a "\" character
. matches any character except line breaks
{2} match exactly 2 of the preceding token (. in this case)
} matches a "}" character

So your python script would be:

import re

PATTERN = r'{\\.{2}}'

text = '{\g1}Hello world!{\i6}'

clean_text = re.sub(PATTERN, '', text)

print(clean_text)

And it would produce the output:

Hello world!
