Question

write a calculator program in Python. The operations your program must compute include, addition(+), subtraction(-), multiplication(*), division(/), and power(**) operations.

Example:

   Enter the first number: 10
   Enter the second number: 2
   Enter the operation: +
   12.0

   Do you wish to exit? n
   Enter the first number: 12
   Enter the second number: 4.2
   Enter the operation: *
   50.400000000000006
   Do you wish to exit? n
   Enter the first number: 10
   Enter the second number: 2
   Enter the operation: **
   100.0
   Do you wish to exit? y
   >>>

Answer 1

ch = 'n'
while(ch=='n'):
    a = float(input("Enter the first number: "))
    b = float(input("Enter the second number: "))
    op = input("Enter the operation: ")
    if(op=='+'):
        print(a+b)
    elif(op=='-'):
        print(a-b)
    elif(op=='*'):
        print(a*b)
    elif(op=='/'):
        print(a/b)
    elif(op=='**'):
        print(a**b)
    else:
        print("Invalid operation",op)
    ch = input("Do you wish to exit? ")
