Exercise 9.1: Making a simple package

Exercise 9.1: Making a simple package

Make a directory called porty/ and put all of the above Python files into it. Additionally create an empty __init__.py file and put it in the directory. You should have a directory of files like this:

porty/
    __init__.py
    fileparse.py
    follow.py
    pcost.py
    portfolio.py
    report.py
    stock.py
    tableformat.py
    ticker.py
    typedproperty.py

Remove the file __pycache__ that's sitting in your directory. This contains pre-compiled Python modules from before. We want to start fresh.

Try importing some of package modules:

>>> import porty.report
>>> import porty.pcost
>>> import porty.ticker

If these imports fail, go into the appropriate file and fix the module imports to include a package-relative import. For example, a statement such as import fileparse might change to the following:

# report.py
from . import fileparse
...

If you have a statement such as from fileparse import parse_csv, change the code to the following:

# report.py
from .fileparse import parse_csv
...
