python3 assert with message code example
Example 1: assert python
x = "hello"
#if condition returns False, AssertionError is raised:
assert x == "goodbye", "x should be 'hello'"
-----------------------------------------------------------------
Traceback (most recent call last):
File "demo_ref_keyword_assert2.py", line 4, in <module>
assert x == "goodbye", "x should be 'hello'"
AssertionError: x should be 'hello'
Example 2: assert python 3
# Simple asserting thing, run it by using pytest or something
# If you don't know how to run pytest, then go learn it.
def test_math():
assert(1 + 1 == 2)
# Another way to test it (without pytest) is:
# You could just run the function to see if it makes an error.
# If it doesn't, it means it was fine, if it does, it means there's an error.
# But then again, using pytest or something is much easier and saves time.
# So try to use testing applications instead of running the function to see.
