Python
Describe how tuples can be useful with loops over lists and dictionaries, and give Python code examples. Create your own code examples. Do not copy them from the textbook or any other source.
Your descriptions and examples should include the following: the zip function, the enumerate function, and the items method.
Python
Type the statements below into your Python interpreter. For each statement, copy the output into your Discussion Assignment and explain the output. Compare it with any similar examples in the textbook, and describe what it means about your version of Python.
>>> print 'Hello, World!'
>>> 1/2
>>> type(1/2)
>>> print(01)
>>> 1/(2/3)

In your program, friends.py, we will practice working with sets. Download the file, people.txt, from Canvas. Read in the file and create a dictionary with the names as keys and the set of interests as values. Display the possible names to the user and then allow the user to choose two names to compare their interests. Make use of exception handling to ensure the 2 names (keys) they have chosen are in the dictionary you have created. If one of the names they enter is not in the dictionary, allow them to choose again until both names are valid. If the user enters 'done', end the program. Then give the user following options for comparing the two people: what they have in common, all interests they don't have in common, what interests are individual to each person, and also to back/choose new people. Create three functions, one for each type of comparison. Use set methods or the short cuts, to get the requested information. Print the result of the comparison chosen. I can give the .txt file upon request.

Write a loop that inputs words until the user enters STOP. After each input, the program should number each entry and print in this format:
#1: You entered _____
When STOP is entered, the total number of words entered should be printed in this format:
All done. __ words entered.
Sample Run
Please enter the next word: cat
#1: You entered cat
Please enter the next word: iguana
#2: You entered iguana
Please enter the next word: zebra
#3: You entered zebra
Please enter the next word: dolphin
#4: You entered dolphin
Please enter the next word: STOP
All done. 4 words entered.
