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?


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!”

a < m and b < n


a < m

b < n
