simple python calculator

#Store number variables for the two numbers

#the sum of the two numbers variable
sum = float(num1) + float(num2)

sum4 = float(num1) / float(num2)

#what operator to use

#different sums based on the operators
if choice == '+':

how to make a calculator in python

#You can change Text at Inputs

num1 = float(input("Enter Firt Number:"))
num2 = float(input("Enter Second Number"))

result= 0
op = str(input("Enter an op(operator)"))
#Gets Input Type--------
try:
  #U can make this in while loop ;-)
  if op=="+":
    result = num1 + num2
  else if op=="-":
    result = num1 - num2
  else if op=="*":
    result = num1 * num2
  else if op=="/":
    result = num1 / num2
  else:
      print("Invalid Input")
  print("The result is " + result)
except ZeroDivisionError:
  print("U cant do that")

Calculator in python

num1 = input("Enter a Number : ")
num2 = input("Enter a Number : ")
result = (num1 * num2)
print(result)
# And then print out the result
