Question

(Triangle Inequality) Write a program triangle.py that takes three integers as command-line arguments and writes True if each one of them is less than or equal to the sum of the other two and False otherwise.

Answer 1

Thanks for the question.

Below is a simple code you will be needing Let me know if you have any doubts or questions.

Thank You !!

===========================================================================

side_one = float(input('Enter side 1: '))
side_two = float(input('Enter side 2: '))
side_three = float(input('Enter side 3: '))

sum_one_two = side_one + side_two
sum_one_three = side_one + side_three
sum_two_three = side_two + side_three

if sum_one_two < side_three or sum_one_three < side_two or sum_two_three < side_one:
    print(False)
else:
    print(True)
