Why are the terms in the prewritten code bracketed (e.g. “(gpa >= 2.0)”)? The code seems to work even without brackets. Is this a style thing?


#3

Can someone tell me why this is returning as " Expected graduation_reqs() with gpa = 0.0 and credits = 0 to return “You do not meet either requirement to graduate!”?

statement_one = False

statement_two = True

def graduation_reqs(gpa, credits):
if (gpa >= 2.0) and (credits >= 120):
return “You meet the requirements to graduate!”
if not credits >= 120:
return “You do not have enough credits to graduate.”
if not gpa >=2.0 :
return “Your GPA is not high enough to graduate”
if (gpa < 2.0) and (credits < 120):
return “You do not meet either requirement to graduate!”

Study your logic. It is testing for one condition and returning. Failing that it is testing the other condition and returning. Failing that it cannot possibly pass the last condition. Bring that conditional to above the other two.

a < m and b < n

then

a < m

b < n
