# Exercise 3.12: Using your library module
|
|
|
|
> Source: Practical Python Programming, `03_Program_organization/04_Modules.md`.

|
|
### Exercise 3.12: Using your library module
|
|
|
|
In section 2, you wrote a program `report.py` that produced a stock report like this:
|
|
|
|
```
|
|
Name Shares Price Change
|
|
---------- ---------- ---------- ----------
|
|
AA 100 9.22 -22.98
|
|
IBM 50 106.28 15.18
|
|
CAT 150 35.46 -47.98
|
|
MSFT 200 20.89 -30.34
|
|
GE 95 13.48 -26.89
|
|
MSFT 50 20.89 -44.21
|
|
IBM 100 106.28 35.84
|
|
```
|
|
|
|
Take that program and modify it so that all of the input file
|
|
processing is done using functions in your `fileparse` module. To do
|
|
that, import `fileparse` as a module and change the `read_portfolio()`
|
|
and `read_prices()` functions to use the `parse_csv()` function.
|
|
|
|
Use the interactive example at the start of this exercise as a guide.
|
|
Afterwards, you should get exactly the same output as before.
