Cómo hacer una calculadora en Python
# Program make a simple calculator
# This function adds two numbers
def add(x, y):
return x + y
# This function subtracts two numbers
def subtract(x, y):
return x - y
# This function multiplies two numbers
def multiply(x, y):
return x * y
# This function divides two numbers
def divide(x, y):
return x / y
# This function exponents two numbers
def exponentiation(x, y):
return x ** y
# This function finds the floor division two numbers
def root(x, y):
return x // y
