[Python] How to make a calculator function that uses the operator as an input? [duplicate]

I started writing a simple calculator in Python. I noticed that the last lines of code that print the equation's result are repeated.

Can I write a function that takes the operator as input and then prints the result with just one line of code?

I imagine it would be something like this:

def result(num1, num2, operator):
print((str(num1)) + " " + str(operator) + " " + str(num2) + " = " + str(num1 **insert operator to compute equation** num2))


What I have currently:

num1 = float(input("Enter first number: "))

op = None
while op not in ("-", "+", "*", "/"):
op = input("Enter operator (-, +, *, /): ")

num2 = float(input("Enter second number: "))

if op == "-":
print((str(num1)) + " " + str(op) + " " + str(num2) + " = " + str(num1 - num2))
elif op == "+":
print((str(num1)) + " " + str(op) + " " + str(num2) + " = " + str(num1 + num2))
elif op == "*":
print((str(num1)) + " " + str(op) + " " + str(num2) + " = " + str(num1 * num2))
elif op == "/":
print((str(num1)) + " " + str(op) + " " + str(num2) + " = " + str(num1 / num2))
