Python Assertion Fail Test

asserttest.py

# In this python command-line assertion test, ENTER
# results in an assertion failure which stops the program.
# Anything else will continue, which results in being asked for
# input again and again.

while True:
    # Get command-line input
    val = input("Press enter to test assertion failure: ")
    # Enter for assertion failure
    if val == "":
        assert val == 1, "assertion failed"
    # Anything else is an assertion pass which interrupts program
    else:
        assert val == val, "assertion passed"
