Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "By default, pandas' .plot() command uses the matplotlib library to display graphs."

A block of code is set as follows:

In [ ]:
     %matplotlib inline
     import quandl

     quandl.ApiConfig.api_key = QUANDL_API_KEY
     df = quandl.get('EURONEXT/ABN.4')
     daily_changes = df.pct_change(periods=1)
     daily_changes.plot();

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
