(Python Example for Beginners)

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:

```Pythagorean theorem calculator! Calculate your triangle sides.
Assume the sides are a, b, c and c is the hypotenuse (the side opposite the right angle
Which side (a, b, c) do you wish to calculate? side>a
Input the length of side b:10
Input the length of side c:15
The length of side a is

Two Machine Learning Fields

There are two sides to machine learning:

• Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. Itâ€™s the mess of reality.
• Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
