The solution provided for the challenge 3 uses >0 or <0 which is incorrect on the first test below is false as the first test is as the number is 0 which is netiher > or <
#print(always_false(0)) which provides None as answer and not false
if (num > 0 and num < 0):
return True
else:
return False
This provide output as none
I had user #if num >=0 or <= 0: which provides the desired false for this output!!
Thankyou, after reviewing again both work EXCEPT the provided answer is much better and will always work. I also read into how to format code and will take on board
