Check whether triangle is valid or not if sides are given in Python
Suppose we have three sides. We have to check whether these three sides are forming a triangle or not.
So, if the input is like sides = [14,20,10], then the output will be True as 20 < (10+14).
To solve this, we will follow these steps −
- sort the list sides
- if sum of first two sides <= third side, then
- return False
- return True
Let us see the following implementation to get better understanding −
Example Code
def solve(sides): sides.sort() if sides[0] + sides[1] <= sides[2]: return False return True sides = [14,20,10] print(solve(sides))
Input
[14,20,10]
Output
True
