Question

“Triangle Guessing” game in Python

The program accepts the lengths of three (3) sides of a triangle as input . The program output should indicate if the triangle is a right triangle, an acute triangle, or an obtuse triangle.

1. Make sure each side of the triangle is a positive integer. Use try/except for none positive integer input.
2. validating the triangle. That is the sum of the lengths of any two sides of a triangle is greater than the length of the third side. Use try/except for invalid sides input.
3. For any wrong input, tell the player what is wrong and asking to re-enter.
4. Allow a player to play multiple times, for example, using a while loop. Remind the player what input to stop the game.
5. user friendly one.
6. add comments:
   1. Introduce/describe the program including the author, date, goal/purpose of the program
   2. Document every variable used at the program even the name is meaningful
   3. Explain/comment operation/activity/logic of your code. For example, “Checking whether the inputs are positive integers” and “Checking the validity the 3 lengths to see if they are able to form a triangle”
7. Testing your program for all possible input and every of the 3 possible triangles

while True:
    try:
        # Check for numbers
        a,b,c = input('Enter 3 numbers (sides of a triangle) : ').split()
        a,b,c = int(a),int(b),int(c)
    except:
        print('Please Enter only Numbers..')
        continue

    # Only positive numbers are accepted
    if a<0 or b<0 or c<0:
        print('Invalid Numbers. Only Positive Numbers are accepted.')
        print('Please Try Again,,,!')
        continue
    # Validate triangle
    if not (a+b > c or b+c >a or a+c > b):
        print('Invalid Sides. These will not form a triangle.')
    else:
        if a>b and b>c:
            longest = a
            other_side1=b
            other_side2=c
        elif b>c:
            longest=b
            other_side1=a
            other_side2=c
        else:
            longest = c
            other_side1 = b
            other_side2 = a

    if longest**2 == other_side1**2 + other_side2**2:
        print('These sides form a right angled triangle.!!')
    elif longest**2 < other_side1**2 + other_side2**2:
        print('These sides form an acute triangle.!!')
    else:
        print('These sides form an obtuse triangle.!!')

    choice = input('Do you want to continue:(Y/N)')
    if not choice=='Y':
        break

print('Bye!!')
