• Question 331:

  Which of the following are the names of Python passing argument styles? (Select two answers.)

  A. keyword
  B. reference
  C. indicatory
  D. positional
  A. keyword
  D. positional

  ---

  Explanation/Reference:

  Keyword arguments are arguments that are specified by using the name of the parameter, followed by an equal sign and the value of the argument. For example, print (sep='-', end='!') is a function call with keyword arguments. Keyword

  arguments can be used to pass arguments in any order, and to provide default values for some arguments1. Positional arguments are arguments that are passed in the same order as the parameters of the function definition. For example,

  print ('Hello', 'World') is a function call with positional arguments. Positional arguments must be passed before any keyword arguments, and they must match the number and type of the parameters of the function2.
