4.8 Using IPython Tab Completion for Discovery

You can view a module’s documentation in IPython interactive mode via tab completion—a discovery feature that speeds your coding and learning processes. After you type a portion of an identifier and press Tab, IPython completes the identifier for you or provides a list of identifiers that begin with what you’ve typed so far. This may vary based on your operating system platform and what you have imported into your IPython session:

In [1]: import math

In [2]: ma<Tab>
           map    %macro   %%markdown
           math   %magic   %matplotlib
           max()  %man

You can scroll through the identifiers with the up and down arrow keys. As you do, IPython highlights an identifier and shows it to the right of the In [] prompt.
