The function body is missing. What snippet would you insert in the line indicated below: ``python 1 def func(number): 2 # insert your code here 3 4 print(func(7)) ``

Question

1 def func(number):
2 # insert your code here
3
4 print(func(7))

Options

• Aprint(number)
• Breturn 'number'
• Cprint(number)
• Dreturn number

• A
  15% (8)
• B
  8% (4)
• C
  2% (1)
• D
  75% (40)

Explanation

Option D (return number) is correct because the function is called inside print(func(7)), meaning func must return a value for print to display it - without a return statement, the function returns None, and print(None) would output None.

• A and C (print(number)) would print 7 from inside the function, then print(func(7)) would still print None - you'd see two lines of output and the outer print call would be useless.
• B (return 'number') returns the string literal "number", not the variable number, so func(7) would always output "number" regardless of the argument passed.

Memory tip: Whenever you see a function call nested inside print(func(...)), the function itself must return - not print - because the outer print is what handles the display.
