I have a TeX document like so

s = '\textbf{1 + 1} \begin{center} \textbf{some text in here:} \end{center} and \textbf{2} etc'

I would like to remove the \textbf{ and the closing brace }

So the final text would look something like this

1 + 1 \begin{center} some text in here: \end{center} and 2 etc'

This is what I have tried so far

import re 

re.sub(r'\textbf{(.*)}', '\\1', s)

    Show us what you have tried to solve this problem. Does it work? If not, what does not work? –  May 02 '18 at 06:56

    One way is to use github.com/alvinwan/texsoup. This is overpowered for the current task, but TexSoup will be useful if your task becomes ever so slightly more complicated (e.g., only replace boldfaced text in `\begin{...}...\end{...}` environments) `soup = TexSoup(r"\textbf{1 + 1} \begin{center} \textbf{some text in here:} \end{center} and \textbf{2} etc"); [sub.replace(sub.args[0]) for sub in soup.find_all('textbf')]; print(soup)` disclaimer: I wrote this lib. also, bad practice to use list comprehension when you don't use the return value – Alvin Wan May 03 '18 at 08:58

You can use the following regex:

\\textbf{([^}]*)}

Explanations:

You were really close to a working regex: you just had to escape the first \ (otherwise \t will be interpreted as tab) and add the condition to accept all characters inside the curvy braces except the } this is done by [^}]

OUTPUT:

1 + 1 \begin{center} some text in here: \end{center} and 2 etc
