You need to show us the contents of your file and what the variables are once you have read them from the file. Please read https://stackoverflow.com/help/how-to-ask — adamfowlerphoto, Jan 28 '18 at 11:16

Assuming this is how you stored the data in you data.txt file:

exampleusername
examplepassword
example@example.com
2018

Then the problem is probably because .readline() returns a \n at the end of each line. To avoid that, you can use .strip() for example to remove that extra character like so:

file = open("data.txt", "r")
username = file.readline().strip()
password = file.readline().strip()
email = file.readline().strip()
year = file.readline().strip()

If your data.txt only has these four lines, you could do it in a shorter way like this:

username, password, email, year = open("data.txt", "r").read().splitlines()
