Here i am sharing a simple program which make a calculator to calculate sum,sub,mul,div you can copy it & paste in your compiler to run & enjoy
''' Program make a simple calculator that can add, subtract, multiply and divide using functions '''
def add(a, b):
return a + b
#subtracts two numbers
def subtract(a, b):
return a - b
def multiply(a, b):
return a * b
def divide(a, b):
return a / b
print("Select operation.")
print("1.Add")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")
choice = input("Enter choice(1/2/3/4):")
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
if choice == '1':
print(num1,"+",num2,"=", add(num1,num2))
elif choice == '2':
print(num1,"-",num2,"=", subtract(num1,num2))
elif choice == '3':
print(num1,"*",num2,"=", multiply(num1,num2))
elif choice == '4':
print(num1,"/",num2,"=", divide(num1,num2))
else:
print("Invalid input")
