You use PythonAnywhere to do the exercises for this course. Follow their instructions to create a free/beginner account. You should not need anything beyond the free account for this account.
Since PythonAnywhere is a shared environment, using
pip the normal way will not work
unless you have created a virtual environment.
pip install 'elasticsearch<7.14.0'
You can set up a virtual environment and then use
pip or just add the
--user parameter to pip.
Also make sure you are doing it for Python 3.
pip3 install --user 'elasticsearch<7.14.0'
Some of the assignments ask you to download a file with code or data to do an assignment. You can do this
by saving the file in your browser to your local computer and then uploading the file to PythonAnywhere. But
there is a much quicker way to do it using the command line and the
wget command (you can also use
curl -O) retrieves a file from the web and stores it locally. For example
in the Linux Shell you can type:
wget https://www.pg4e.com/code/elasticbook.py wget https://www.pg4e.com/code/hidden-dist.py wget https://www.pg4e.com/gutenberg/cache/epub/18866/pg18866.txt
And these files will be downloaded.
The beginner accounts on PythonAnywhere are behind a firewall so you can only access pre-approved web sites - so don't be surprised if you get an error like:
$ wget http://www.amazon.com/ --2020-10-28 12:30:25-- http://www.amazon.com/ Resolving proxy.server (proxy.server)... 10.0.0.98 Connecting to proxy.server (proxy.server)|10.0.0.98|:3128... connected. Proxy request sent, awaiting response... 403 Forbidden 2020-10-28 12:30:25 ERROR 403: Forbidden.
curl commands are powerful command line tools that are very helpful when logged into
a Linux system in the cloud.
