Fibonacci with try/except

def fibonacci(n):

    return 0

  else:
    return fibonacci(n-1) + fibonacci(n-2)
    # Goes through fibonacci. Loop. Adds. This is the original code for fibonacci.

  try:
    num = int(input("Enter a number for fibonacci: "))
    if num < 0:
      raise ValueError
      # If the number is negative, the code won't work, so we need to show the user there is an error.
      
    for n in range(num + 1):
      if n == num:
        print(fibonacci(n))
        # Prints fibonacci sequence for whatever n is
      else:
        print(fibonacci(n), end=", ")
