Accessing Python object information in Jupyter

[mmcky]

One of the great features of Jupyter is the live object inspection to obtain information about functions and methods.

To see what functions / methods are available through the objects interface you can:

import numpy as np
np.<tab> #Use the tab key in place of <tab>

To obtain the function signature or the parameter definitions you can:

import numpy as np
np.array(<shift>+<tab> #Replace <shift>+<tab> with the key combination after the open bracket

To get the full docstring:

import numpy as np
np.array(<shift>+<tab>+<tab> #Replace <shift>+<tab> plust another <tab> with the key combination after the open bracket to display more of the docstring

Another way to access this information is using the ? character in Jupyter

import numpy as np
np.array?

then execute the statement to obtain an information window at the bottom of your browser.
