How to separate a command from the rest of the message in telegram bots with pyTelegramBotAPI?

Question

For example in the following command

/set first_name, last_name

How to separate or remove /set from the rest of the message?

Answer 1

Since commands can use only latin letters, numbers and underscores, you can separate it with the tiny regular expression, like this:

    import re
    pattern = "^\/[a-zA-Z\d_]* (.*)$"
    string = "/set first_name, last_name"
    match = re.match(command_pattern , string)
    message = match.group(1)  
    # first_name, last_name

Another solution:

string = "/set first_name, last_name"
message = " ".join(string.split(" ")[1:])
# first_name, last_name

But the limitation of the last method is that it removes double spaces from the string if they existed.
