Python Math: Create a Pythagorean theorem calculator

Python Math: Exercise-68 with Solution

Write a Python program to create a Pythagorean theorem calculator.

Note : In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Sample Solution:-

Python Code:

from math import sqrt

print('Pythagorean theorem calculator! Calculate your triangle sides.')
print('Assume the sides are a, b, c and c is the hypotenuse (the side opposite the right angle')
formula = input('Which side (a, b, c) do you wish to calculate? side> ')

if formula == 'c':
	side_a = int(input('Input the length of side a: '))
	side_b = int(input('Input the length of side b: '))

	side_c = sqrt(side_a * side_a + side_b * side_b)
	
	print('The length of side c is: ' )
	print(side_c)

elif formula == 'a':
    side_b = int(input('Input the length of side b: '))
    side_c = int(input('Input the length of side c: '))
    
    side_a = sqrt((side_c * side_c) - (side_b * side_b))
    
    print('The length of side a is' )
    print(side_a)

elif formula == 'b':
    side_a = int(input('Input the length of side a: '))
    side_b = int(input('Input the length of side c: '))
        
    side_c = sqrt(side_c * side_c - side_a * side_a)
    
    print('The length of side b is')
    print(side_c)

else:
	print('Please select a side between a, b, c')

Sample Output:

Input the length of side b:10                                                                                 
Input the length of side c:15                                                                                 
The length of side a is

Python: Tips of the Day

Measure the execution time of small bits of Python code with the "timeit" module.

Example:

import timeit
print(timeit.timeit('"-".join(str(n) for n in range(100))',
number=100000))

print(timeit.timeit('"-".join([str(n) for n in range(100)])',
number=100000))

print(timeit.timeit('"-".join(map(str, range(100)))',
number=100000))
