Generate random numbers after a string

I'm currently trying to write a script that will allow generating random numbers before a string, I expect to have lines of code which have my random numbers + the string for ex: "328188123@gmail.com" "283821813@gmail.com" I'm currently a beginner and so if anyone can help that would be great. I've tried to resolve my issue by figuring out a way to implement the random function before the string but I can't seem to find a-way.

import random
print(random.randint(0,100000))

G = "@gmail.com"
