Is this a triangle.py

# Implement a function that accepts 3 integer values a, b, c. The function should return true if a triangle can be built with the sides of given length and false in any other case.

# (In this case, all triangles must have surface greater than 0 to be accepted).

# Examples:

# Input -> Output
# 1,2,2 -> true
# 4,2,3 -> true
# 2,2,2 -> true
# 1,2,3 -> false
# -5,1,3 -> false
# 0,2,3 -> false
# 1,2,9 -> false 

def is_triangle(a, b, c):
    s = sorted([a,b,c])
    return (s[0] + s[1])>s[2]
