Question

Write a program which:
- prompts the user for 2 numerical inputs
- stores their two inputs in variables as floats
- Use a while in loop to ask a user for a valid operation: (if the user's
input operation isn't one of those listed above, instead print a message telling
them so, and continue asking for the valid operation)
- prompts the user for an arithmetic operation ( + - * / %)
- stores the user's input as a string
- stores the result of the specfied operation with the specified
numbers
- if the inputs are invalid for the operation (i.e. dividing by
0) print a message informing the user and Use a while in loop to ask a user for a
valid input and then calculate and print out the new result
- if the inputs were valid, prints out the resulting equation
- for instance, if the user enters '2' '3' and '+' then "2.0 +
3.0 = 5.0" should be printed

please use python 3

Answer 1

a=input("Enter num1:")                      #num1 input
b=input("Enter num2:")                      #num2 input
n1=float(a)                                 #converting to float
n2=float(b)                                 #converting to float
res=0                                       #result variable
while(True):                                #infinite loop until valid operation is performed
    print("Enter + or - or * or / or % :") #user prompt
    ip=str(input("Enter operation:"))       #input from user to perform an operation
    if(ip=='+'):
        res=n1+n2
        break
    elif(ip=='-'):
        res=n1-n2
        break
    elif(ip=='*'):
        res=n1*n2
        break
    elif(ip=='/' and n2!=0):
        res=n1//n2
        break
    elif(ip=='%' and n2!=0):
        res=n1%n2
        break
print(res)                              #printing result
