Use pure Python packages

- [Instructor] Now that we've looked at data frames…and time zones,…let's get back to our goal…which is to calculate how slowly I jog.…We have the time but to calculate speed…we need distance data as well.…We have latitude and longitude.…and to calculate the distance on Earth's surface,…we're going to use a small pure Python Package.…I'm going to grab geo.py from the exercise files…to where the Jupyter notebook is running.…By default, the notebook will run in your home directory.…However you can check the current directory…with the percent pwd magic.…

So I'm going to go to where the exercise files are,…copy the geo.py file.…And then select Go and Home…and paste it there.…Now we can import the module,…import geo.…If you get an import error…this means that geo.py is not located in one of…the directories that Python is looking for models in.…You can view this list by running the following code.…We'll import sys…and look at sys.path.…

As long is geo.py is in one of these directories…you should be fine.…The other option is to edit directory…
