### Third Party Functions

A better option is to use descriptors.

A solution from the [quantecon

library](https://github.com/QuantEcon/QuantEcon.py/tree/master/quantecon)

library](https://github.com/QuantEcon/QuantEcon.py/tree/main/quantecon)

using descriptors that behaves as we desire can be found

```{solution-end}

An example solution is given below.

In essence, we've just taken [this code](https://github.com/QuantEcon/QuantEcon.py/blob/master/quantecon/ecdf.py)

In essence, we've just taken [this code](https://github.com/QuantEcon/QuantEcon.py/blob/main/quantecon/ecdf.py)

from QuantEcon and added in a plot method

```{code-cell} python3

The World Bank [collects and organizes data](https://data.worldbank.org/indicator) on a huge range of indicators.

For example, [here's](https://data.worldbank.org/indicator/GC.DOD.TOTL.GD.ZS/countries) some data on government debt as a ratio to GDP.

The next code example fetches the data for you and plots time series for the US and Australia

reversed would be very hard to read, even if the author told you so on the

first page.

In Python, the standard style is set out in [PEP8](https://www.python.org/dev/peps/pep-0008/).

(Occasionally we'll deviate from PEP8 in these lectures to better match mathematical notation)

True, the code more or less follows [PEP8](https://www.python.org/dev/peps/pep-0008/).

At the same time, it's very poorly structured.
