# Python Classes and Data Structures: Practice Problems + Reading
|
|
|
|
In this homework, you're going to write code for two challenge problems.
|
|
|
|
You'll practice these programming concepts we've covered in class:
|
|
|
|
* Using dictionaries to solve problems.
|
|
* Storing data in tuples and sets.
|
|
|
|

|
|
|
|
## Deliverables
|
|
|
|
Part of this homework will be code challenges and part of it will be some reading with comprehension questions.
|
|
|
|
For each of the code challenges listed below, you will create a new `.py` file and write code to solve the problem. For example, you would create `problem1.py` with your solution code to the first problem. Run the file from the command line to check your work.
|
|
|
|
*Reminder: On your laptop, you can run the file from your command line with the following:*
|
|
|
|
```python
|
|
python problem1.py
|
|
```
|
|
|
|
> **Hint:** Make sure you are printing something out with the `print` statement. Otherwise, you won't see any output from running your program!
|
|
|
|
|
|
## Requirements:
|
|
|
|
By the end of this, you should have:
|
|
* Two different `.py` files (one for each code challenge).
|
|

# Code Challenges

|
## Problem 1: I Love You, Tuple
|
|
|
|
### Skill you're practicing: Using tuples.
|
|
|
|
You may recall tuples from your in-class lesson. Tuples are *immutable* data structures, which means they can't be changed after they're created. They are typically used to store related information that doesn't need to be changed, such as a student record or, in this case, some stats about a movie. It's your job to create some `print` statements that access the appropriate values inside each tuple to produce the expected output.
|
|
|
|
|
|
#### Starter Code
|
|
|
|
```python
|
|
# My favorite romance movies
|
|
# title, release year, runtime, tagline, main characters
|
|
romantic_movie1 = ("The Princess Bride", 1987, 98, "The story of a man and a woman who lived happily ever after.", ["Buttercup", "Westley", "Fezzik", "Inigo Montoya", "Vizzini"])
|
|
romantic_movie2 = ("Groundhog Day", 1993, 101, "He's having the day of his life… over and over again.", ["Phil Connors"])
|
|
romantic_movie3 = ("Amélie", 2001, 122, "One person can change your life forever.", ["Amélie Poulain", "Nino Quincampoix", "The Garden Gnome"])
|
|
```
|
|
|
|
#### Expected Output
|
|
|
|
```
|
|
Here are my favorite romance movies:
|
|
|
|
The Princess Bride (1987): The story of a man and a woman who lived happily ever after.
|
|
|
|
Groundhog Day (1993): He's having the day of his life...over and over again.
|
|
|
|
Amélie (2001): One person can change your life forever.
|
|
```
|
|
|
|
**Hint:** Remember, you can access a tuple sort of like a list, with the square brackets `[]` counting from zero (e.g., the value of `romantic_movie1[0]` is `"The Princess Bride"`).
|
|
|
|
### Bonus:
|
|
Change the `print` statement's separator character to an empty string `""` instead of a space so that you can print the year as `(1987)` instead of `( 1987 )`.

## Problem 2: Friends, Colleagues, and Details
|
|
|
|
### Skill you're practicing: Using dictionaries, lists, and key-value pairs.
|
|
|
|
Your boss tasks you with creating a company directory. Make a list called `employees`, which will contain one dictionary per person and include the keys `name`, `age`, `department`, `phone`, and `salary`. Once you have the list of dictionaries set up, loop through the list and print out the `name`, `department`, and `phone` number of each employee. Their `age` and `salary` should remain secret!
|
|
|
|
#### Starter Code
|
|
|
|
A dictionary should be set up in the following way:
|
|
|
|
```python
|
|
{
|
|
"name": "Ron Swanson",
|
|
"age": 55,
|
|
"department": "Management",
|
|
"phone": "555-1234",
|
|
"salary": "$87,000"
|
|
}
|
|
```
|
|
|
|
#### Expected Output
|
|
|
|
```
|
|
Ron Swanson in Management can be reached at 555-1234.
|
|
Leslie Knope in Middle Management can be reached at 555-4321.
|
|
Andy Dwyer in Shoe Shining can be reached at 555-1122.
|
|
April Ludgate in Administration can be reached at 555-3345.
|
|
```
|
|
|
|
**Hint:** Dictionaries have values that can be accessed with keys, for example, `employees["name"]`. Keys are typically strings.
