Examples

Below are a couple of examples for how you should go about this assignment.

Example 1:

Setup

1. Navigate to your repository in the command line.

• You can either use the cd PATH_TO_FOLDER command.
  • In my case the command was cd /Users/wesreed/git/School/IT3049/Python-Basics
  • Use the pwd command to Print Working Directory and confirm your location
• OR You could open VSCode integrated terminal window and it will open in the terminal already in the right path.

2. Installing the dependencies pip install -r requirements.txt

3. Run the tests using pytest.

   

• Notice all the errors, our goal for this assignment is to resolve them all.

Getting Down to Business

1. Open the project in Visual Studio Code (Not Visual Studio)

   

   Let's try to solve a couple of those tests.

2. Open the file numbers_1.py. Particularly

   # parse_int: should convert strings to integer numbers
   def parse_int (str):
     return
   • Notice the function have an empty implementation. - We need to do something about that 🤔

3. Consulting the Python documentation for built-in functions. The documentations shows usage examples, and specifies the parameters and return type of the function.

   

   Key Takeaways:

     # parse_int: should convert strings to integer numbers
     def parse_int (str):
       return int(str)
   • Don't forget to return something from the function.

4. Re-run the tests again and let's see if it passes

   

5. Commit your code git commit -m "finished test parseInt".

Example 2:

1. Well, no need for the setup steps here (you should already be in the directory)
2. Open the file lists_3.py. Particularly at this function

     '''
     IndexOf: you should be able to determine the location of an item in an list
     Example:
     arr = [1,2,3,5,6]
     calling the function like
     index_of(arr, 3) should return the index 2
     '''
     def index_of(arr, item):
         return
3. The index_of method is supposed to return the index of a certain element in a list. You can learn more about Python Built-in method here
4. My implementation for this is as follows

     def index_of(arr, item):
       return arr.index(item)
5. Re-run the tests again and let's see if it passes
6. Commit your code git commit -m "finished test: IndexOf".

On to the next test .. Rinse 🧼 and Repeat 🔁
