Problem with python code

Question

def max_of_three(a,b,c):
if a>b and a>c:
return a
elif b>a and b>c:
return b
else
return c

print(max_of_three(1,2,3))

what is the problem with this code? it always stops on 2nd line

Answer 1

#copy and run this instead, it works :

def max_of_three(a,b,c):
if a>b and a>c:
return a
elif b>a and b>c:
return b
else:
return c
print(max_of_three(1,2,3))

Answer 2

max = a if a > b and a > c else b if b > c else c
