I dont know why it is not best practice :>

Python fork

• imports
• uses blocks
• approx equal
• random tests adapted to cover recent issue
• manages ref_sol upgrade to Python 3

see the comments below. this solution was written in Pyrthon 2. Python 3 changed the round() function for halfway cases: it used to be half away from zero (0.5 --> 1, 1.5 --> 2), now it's half towards the nearest even integer (the so-called "banker's rounding"): (0.5 --> 0, 1.5 --> 2)

Random tests in all languages should prevent solutions like this one in Python.

upgrading to issue

approved

Took longer than it should. Have a blessed day... NOT

This shouldn't be valid, but the test literally doesn't work in py 3

How come when I did it it was incorrect????
Which verion did you do?

This probably should be 7kyu.
6kyu usually makes me sit thinking, this was way too easy imo.

OwO

def price(a: int, b: int) -> int:
if a == 0:
t = 0
elif b == 0:
t = 0
else:
a = a + b
b = b - 0
t = a * b - b ** 2
return t

lol, i just changed the test code function name to f from fun. this is so cursed!

Approved.
