How to update a Python string in a for loop?-CodePudding

I am building a Discord bot using the discord.py library. The library uses the on_message(ctx) event to let us modify a message if we want to. What I would like to do is to remove the formatting and replace the user mentions with the Discord names. The text of the message looks like this:

<@!34565734654367046435>  <@!34565734645354367046435> are you here?

In the ctx variable I can get the mentions as User objects from ctx.mentions and I can get the NAME and the ID of each mentioned user.

I'd like to replace the <@!34565734654367046435> with the name of the user. The result to be something like:

Name1 Name2 are you here?

This is what I have so far but it does not seem to work.

remove_formatting = utils.remove_markdown(context.content)
print(remove_formatting) # prints the very first code styled line in this question
for member in context.mentions:
   remove_formatting.replace(f'<@!{member.id}>', member.name)

If I print the member.id and the member.name without doing anything else, I get the expected values. How do I update the string in this for loop?

CodePudding user response：

The replace function returns a new string, it doesn't edit the existing string in place. If you edit your loop to:

remove_formatting = utils.remove_markdown(context.content)
for member in context.mentions:
   remove_formatting = remove_formatting.replace(f'<@!{member.id}>', member.name)

it should work.
