how to make a addition calculator in python code example
Example 1: how to make a calculator using idle
def calculate():
operation = input('''
Please type in the math operation you would like to complete:
+ for addition
- for subtraction
* for multiplication
/ for division
''')
number_1 = int(input('Please enter the first number: '))
number_2 = int(input('Please enter the second number: '))
if operation == '+':
print('{} + {} = '.format(number_1, number_2))
print(number_1 + number_2)
elif operation == '-':
print('{} - {} = '.format(number_1, number_2))
print(number_1 - number_2)
elif operation == '*':
print('{} * {} = '.format(number_1, number_2))
print(number_1 * number_2)
elif operation == '/':
print('{} / {} = '.format(number_1, number_2))
print(number_1 / number_2)
else:
print('You have not typed a valid operator, please run the program again.')
again()
def again():
calc_again = input('''
Do you want to calculate again?
Please type Y for YES or N for NO.
''')
if calc_again.upper() == 'Y':
calculate()
elif calc_again.upper() == 'N':
print('See you later.')
else:
again()
calculate()
Example 2: how to make a python calculator
import time
def add():
n1 = input('Enter a number: ')
n2 = input('Enter another number: ')
time.sleep(1)
print(int(n1)+int(n2))
def multiply():
n1 = input('Enter a number: ')
n2 = input('Enter another number: ')
time.sleep(1)
print(int(n1)*int(n2))
def divide():
n1 = input('Enter a number: ')
n2 = input('Enter another number: ')
time.sleep(1)
print(int(n1)int(n2))
def subtract():
n1 = input('Enter a number: ')
n2 = input('Enter another number: ')
time.sleep(1)
print(int(n1)-int(n2))
run = True
while run:
ans = input('Select an opreation: ')
if(ans=='Addition'):
add()
if(ans=='Divide'):
divide()
if(ans=='Multiply'):
multiply()
if(ans=='Subtract'):
subtract()
