3You can guess it. You evaluate the boolean value (i.e. result of comparison operator), and if it's `False`, you terminate with an error and show `msg` error message – Alexey S. Larionov Jan 14 '21 at 12:18

This expression can't be truth, btw. – Olvin Roght Jan 14 '21 at 12:19

2@OlvinRoght of course it can, `res` just needs to have the value `"PASS"`. – Masklinn Jan 14 '21 at 12:26

@Masklinn, oh, you're right, my bad. – Olvin Roght Jan 14 '21 at 12:52

The assert keyword is used when debugging the code.
This keyword test a condition (which is the first argument), if the condition returns false the program will give an AssertionError, you can write the AssertionError message (which is the second argument, separated with ,).
Ex:
password = "hello"
assert password == "goodbye", "Access Denied"
output of the above code is:
AssertionError: Access Denied

Also your assertion makes no sense. You assert that the value is `goodbye` and print that it should be `hello` if it wasn't `goodbye`. I mean, thee password actually ***is*** hello and your message says it should be hello – Tomerikoo Jan 14 '21 at 12:44
