python三角形判定怎么做

a = int(input("The length of the side a = "))

b = int(input("The length of the side b = "))

c = int(input("The length of the side c = "))

if a != b and b != c and a != c:

    print("This is Scalene") #不规则三角形

elif a == b and b == c:

    print("This is an Equilateral") #等边三角形

else:

    print("This is Isosceles") #等腰三角形

The length of the side a = 3

The length of the side b = 4

The length of the side c = 5

This is Scalene

The length of the side a = 3

The length of the side b = 3

The length of the side c = 3

This is an Equilateral

The length of the side a = 3

The length of the side b = 3

The length of the side c = 4

This is Isosceles
