Homework 2

Due: Thursday, February 13 at 11:59 pm

Instructions

Please read the instructions carefully. An incorrectly formatted submission may not be counted.

There are two questions in this assignment. For each question, put your answer in a plain text python file (.py) named q1.py and q2.py. Please include comments in your code detailing your thought process where appropriate. Include any test cases to ensure your code works, as we did in the in-class examples. Put q1.py and q2.py in a folder called uni-hw2 (so for me this would be tkp2108-hw2). Then compress this folder into a .zip file. For most operating systems, you should be able to right click and have a “compress” option in the context menu. This should create a file called tkp2108-hw2.zip (with your uni). Submit this on courseworks.

Note: You can consider the example outputs the result of a “minimum viable solution”. There are many different ways to accomplish the same functionality, and you should feel free to add any additional functionality or get creative so long as this functionality remains. As always, please feel free to ask clarifying questions.

Part 1 - Weight Converter

Weight is a function of the gravitational pull of one mass on another. On a planet with less mass, like Mercury, you weight less than Earth, while on a planet with greater mass like Neptune, you weight more.

Write a Python program that does the following:

First, ask the user to input a sequence of names and multipliers, like mercury,0.38, followed by enter
Have them hit enter without typing anything to continue, as in HW1
Next, prompt them for their weight
Next, prompt them which entry they want to convert to
Display their weight for that entry
Prompt them again for the entry they want to convert to, or empty to finish

Here is an example sequence from my solutions:

> Hello!
> Please type in a pair of (planet,multiplier), or hit enter to continue: mercury,0.38
> Please type in a pair of (planet,multiplier), or hit enter to continue: venus,0.91
> Please type in a pair of (planet,multiplier), or hit enter to continue: mars,0.38
> Please type in a pair of (planet,multiplier), or hit enter to continue: jupiter,2.34
> Please type in a pair of (planet,multiplier), or hit enter to continue: saturn,0.93
> Please type in a pair of (planet,multiplier), or hit enter to continue: uranus,0.92
> Please type in a pair of (planet,multiplier), or hit enter to continue: neptune,1.12
> Please type in a pair of (planet,multiplier), or hit enter to continue: moon,0.165
> Please type in a pair of (planet,multiplier), or hit enter to continue: ceres,0.04
> Please type in a pair of (planet,multiplier), or hit enter to continue: pluto,0.063
> Please type in a pair of (planet,multiplier), or hit enter to continue: neutron star,260000000000
> Please type in a pair of (planet,multiplier), or hit enter to continue:
> Please tell me your weight on Earth: 150
> Where do you want to know your weight? (or hit enter to exit) pluto
> Your weight on pluto is: 9.45
> Where do you want to know your weight? (or hit enter to exit) jupiter
> Your weight on jupiter is: 351.0
> Where do you want to know your weight? (or hit enter to exit)
> Bye!

Part 2 - Anonymizer

Let’s imagine we want to remove sensitive information from some text. Write a Python program that does the following:

Prompt the user to input a block of text
Prompt the user to input a comma-separated list of words to remove
Display the block of text with the words replaced by *

Here is an example sequence from my solutions. NOTE: Be sure to only replace whole words! Notice below that we do not replace the text when it appears as part of a larger word.

> Please type in a block of text from which to prune sensitive information: Lorem ipsum dolor sit amet, consectdolor asitamet samet
> Please type in a comma-separated list of words to remove: dolor,sit,amet
> Here is your anonymized text: Lorem ipsum ***** *** ****, consectdolor asitamet samet
