Replace strings that starts with a char and ends with space

I have trouble putting quotes to strings with the char @ and ends with the space, for example:

mystring = "@id string,@type string,account struct<@id string,@type string,accountId:string>"
mystring_expected = "`@id` string,`@type` string,account struct<`@id` string,`@type` string,accountId:string>"

How can I do it in Python?

>Solution :

you could use a regular expression to find the words and put quotes using the re.sub function:

import re

mystring = "@id string,@type string,account struct<@id string,@type string,accountId:string>"

pattern = r"(@\w+\b)"
mystring_expected = re.sub(pattern, r"`\1`", mystring)
print(mystring_expected)
