Question

Python

10 - (10 pts) - Implement a program that starts by asking the user to enter a userID (i.e., a string). The program then checks whether the id entered by the user is in the list of valid users.

The current user list is: ['joe', 'sue', jamal, 'sophie']

Depending on the outcome, an appropriate message should be printed. Regardless of the outcome, your function should print 'Done.' before terminating.

Here is an example of a successful login:

>>> Login: joe

Welcome back, joe

Done.

And here is one that is not:

>>> Login: john

Unknown users or passwords

Done.

11 – (10 pts) - Using Python, create a random password generator with length = 10 characters. The password should consist of upper- and lower-case letters and digits.

12 - (15 pts) - An acronym is a word formed by taking the first letters of the words in a phrase and then making a word from them. For example, RAM is an acronym for random access memory.

Write a function acronym() that takes a phrase (i.e., a string) as input and then returns the acronym for that phrase.

Note: The acronym should be all uppercase, even if the words in the phrase are not capitalized.

>>> acronym('Random access memory')

'RAM'

>>> acronym('central processing unit')

'CPU'

13 - (10 pts) – Using Python, write a segment of code to populate the table "employee" of the database "EmployeeDB” with the data below. Import your choice of DB connector (import MySQLdb/sqlite3…)

Create the“employee” table with schema = [name, address, age]

Insert this employee: John Doe, 7001 E Williams Field, 32

14 - (20 pts) - Define a class called Animal that abstracts animals and supports three methods:

setSpecies(species): Sets the species of the animal object to species.

setLanguage(language): Sets the language of the animal object to language.

speak(): Prints a message from the animal as shown below.

The class must support supports a two, one, or no input argument constructor.

Then define Duck as a subclass of Animal and change the behavior of method speak() in class Duck.

>>> snoopy = Animal('dog', 'bark')

>>> snoopy.speak()

I am a dog and I bark.

>>> tweety = Animal('canary', ‘tweet’)

>>> tweety.speak()

I am a canary and I tweet

>>> animal = Animal()

>>> animal.speak()

I am an animal and I make sounds.

>>> daffy = Duck()

>>> daffy.speak()

quack! quack! quack!
