calculator with python code example

Example 1: simple python calculator

#Store number variables for the two numbers

num1 = input('Enter first number: ')
num2 = input('Enter second number: ')

#the sum of the two numbers variable
sum = float(num1) + float(num2)
sum2 = float(num1) - float(num2)
sum3 = float(num1) * float(num2)
sum4 = float(num1) / float(num2)

#what operator to use
choice = input('Enter an operator, + = addition, - = subtraction, * = multiplication and / = division: ')
#different sums based on the operators
if choice == '+':
  print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

  if choice == '-':
    print('The sum of {0} and {1} is {2}'.format(num1, num2, sum2))

if choice == '*':
    print('The sum of {0} and {1} is {2}'.format(num1, num2, sum3))

if choice == '/':
    print('The sum of {0} and {1} is {2}'.format(num1, num2, sum4))

Example 2: calculator python tutorial

while True:
    Cal = input("")

    print(eval(Cal))

Example 3: python calculator

num_one = int(input("Enter 1st number: "))

op = input("Enter operator: ")

num_two = int(input("Enter 2nd number: "))

if op == "+":
    print(num_one + num_two)
elif op == "-":
    print(num_one - num_two)
elif op == "*" or op == "x":
    print(num_one * num_two)
elif op == "/":
    print(num_one / num_two)

Example 4: calculator code

x = input("first number")
y = input("second number")
z = input("do you want to multiply, minus, divide or add? (x,-,/,+)")

y = int(y)
x = int(x)

if z == "+":
    print (x + y)

if z == "/":
    print (x / y)

if z == "x":
    print (x * y)

if z == "-":
    print (x - y)

else:
    print("use x,-,/ or + next time!")

Example 5: calculator with python

#Simple python Calculator
#Enter the first variable
#then the operator
#and finally the second variable, then the answer is printed.
A = int(input("Enter your first number: "))
operator = input("Which operation would you like to perform? (+, -, /, *, //, **): ");
B = int(input("Enter your second number: "))
#Addition
if operator == "+":
    ans = A + B
    print(str(ans))
#Subraction
elif operator == "-":
    ans = A - B
    print(str(ans))
#division
elif operator == "/":
    ans = A / B
    print(str(ans))
#Multiplication
elif operator == "*":
    ans = A * B
    print(str(ans))
#Integer division
elif operator == "//":
    ans = A // B
    print(str(ans))
#Exponent
elif operator == "**":
    ans = A ** B
    print(str(ans))
else:
    print("wrong operator!")

Example 6: how to make a calculator in python

def add(num1, num2):
    return num1 + num2

def subtract(num1, num2):
    return num1 - num2

def multiply(num1, num2):
    return num1 * num2

def divide(num1, num2):
    return num1 / num2
