# Syntax error and im a beginner

#### C0D3DSK1llS

###NOT SURE WHAT IM DOING WRONG.
==========================================================

Code:
``````print("Select operation.")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")
while True:
# take input from the user
choice = input("Enter choice(1/2/3/4): ")

# check if choice is one of the four options
if choice in ('1', '2', '3', '4'):
num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))

if choice == '1':
print(num1, "+", num2, "=", add(num1, num2))

elif choice == '2':
print(num1, "-", num2, "=", subtract(num1, num2))

elif choice == '3':
print(num1, "*", num2, "=", multiply(num1, num2))

elif choice == '4':
print(num1, "/", num2, "=", divide(num1, num2))

# check if user wants another calculation
# break the while loop if answer is no
next_calculation = input("Let's do next calculation? (yes/no): ")
if next_calculation == "no":
break

else:
print("Invalid Input")``````

I keep getting this syntax error
Traceback (most recent call last):
File "/home/anonymous/Desktop/print.py", line 22, in <module>
print(num1, "*", num2, "=", multiply(num1, num2))
NameError: name 'multiply' is not defined

your getting that error because python doesn't have a default multiply function. you'll need to write it.
