def calculetor():

operation = input('''
Please type in the math operation you would like to complete:
+ for addition
- for subtraction
* for multiplication
/ for division
** for power
% for modulo
Enter Your Choise:
''')

print(f"{num1} + {num2} = {num1 + num2}")
elif operation == '-':
print(f"{num1} - {num2} = {num1 - num2}")
elif operation == '*':
print(f"{num1} * {num2} = {num1 * num2}")
elif operation == '/':
print(f"{num1} / {num2} = {num1 / num2}")
elif operation == '**':
print(f"{num1} ** {num2} = {num1 ** num2}")
elif operation == '%':
print(f"{num1} % {num2} = {num1 % num2}")

print("You Press a Invalid Key")

Do you want to calculate again?
Please type y for YES or n for NO.
''')
if cal_again == 'y':
calculetor()
elif cal_again == 'n':
print("See You Later")
else:
again()
calculetor()
Output:
Wellcome to Calc:
Please type in the math operation you would like to complete:
+ for addition
- for subtraction
* for multiplication
/ for division
** for power
% for modulo
Enter Your Choise:
+
Enter first Number: 2
Enter second Number: 3
2 + 3 = 5
Do you want to calculate again?
Please type y for YES or n for NO.
n
See You Later
In this program, we ask the user to choose the desired operation. Options +, -, *, /, **, % are valid. Two numbers are taken and an if...elif...else branching is used to execute a particular section. User-defined functions calculator and again evaluate respective operations.
