Question

# IT HAS BEEN CORRECTED

#welcome statement
print("This is a basic calculator, fill in each field and press the enter button to proceed")
print("What operation do you want to perform?")

#operation
print("""1. Addition
2. Subtraction
3. Multiplication
4. Division
5. Exponent""")

#function definition
def add(x, y):
return x+y

def sub(x, y):
return x-y

def mul(x, y):
return x*y

def div(x, y):
return x/y

def expo(x, y):
return x**y

#User input
operation = input("Enter operator: ")
n1 = float(input("Enter first number: "))
n2 = float(input("Enter second number: "))

if operation == "1":
print(n1, '+' , n2, '=', add(n1, n2))
elif operation == '2':
print(n1, '-', n2, '=', sub(n1, n2))
elif operation == '3':
print(n1, '*', n2, '=', mul(n1, n2))
elif operation == '4':
print(n1, '/', n2, '=', div(n1, n2))
elif operation == '5':
print(n1, '**', n2, '=', expo(n1, n2))
else:
print("Please enter a valid operator")
