Sure, here is the completed Python code:

```python
# Define a recursive function to calculate the factorial of a number
def factorial(n):
# Base case: If n is 0 or 1, return 1
if n == 0 or n == 1:
return 1
else:
# Calculate the factorial recursively
return n * factorial(n-1)

# Test the function
number = int(input("Enter a non-negative integer: "))
print("Factorial of", number, "is:", factorial(number))
```

In the recursive function, the missing part is `factorial(n-1)`. This is because the factorial of a number `n` is the product of `n` and the factorial of `n-1`.

In the print statement, the missing part is `factorial(number)`, which calls the function with the input number and prints the result.
