Goal:

Develop an understanding of using advanced argument passing and parameter definitons.

Procedure

Keyword arguments:

• Write a function that has four optional parameters (with defaults):
  • fore_color
  • back_color
  • link_color
  • visited_color
• Have it print the colors (use strings for the colors)
• Call it with a couple different parameters set
  • using just positional arguments:
    • func('red', 'blue', 'yellow', 'chartreuse')
  • using just keyword arguments:
    • func(link_color='red', back_color='blue')
  • using a combination of positional and keyword
    • ``func('purple', link_color='red', back_color='blue')
  • using *some_tuple and/or **some_dict
    • regular = ('red', 'blue')
    • links = {'link_color': 'chartreuse'}
    • func(*regular, *links)

Generic parameters:

• Write a the same function with the parameters as:

*args and **kwags

• Have it print the colors (use strings for the colors)
• Call it with the same various combinations of arguments used above.
• Also have it print args and kwargs directly, so you can be sure you understand what’s going on.
• Note that in general, you can’t know what will get passed into **kwargs So maybe adapt your function to be able to do something reasonable with any keywords.
