I recently started programming using Python. I have to write many functions and was wondering how I can incorporate a help or description text such that it appears in the object inspector of Spyder when I call the function.
In MATLAB, this worked by putting commented text at the beginning of the function file. Is there a similar method in Python (using Spyder)?
By default, the first string in the body of a method is used as its docstring (or documentation string). Python will use this when help() is called for that method.
def foo(bar):
"""
Takes bar and does some things to it.
"""
return bar
help(foo)
foo(bar)
Takes bar and does
some things to it
You can read more about how this works by reading PEP-258, and this question goes into some more details.
(Spyder maintainer here) There are other couple of things you need to know (besides what @burhan-khalid mentioned) regarding Spyder itself:
If you want to see your docstrings nicely formatted in the Help pane, you need to write them following the numpydoc standard, which is explained here. This is a set of conventions used by almost all python scientific packages to write their docstrings. It's not mandatory but we follow it too while converting docstrings (which come in plain text) to html.
You have to use Ctrl+I in front of an object's name to show their help in our Help pane.
In a short answer. This can be done by putting text between triple quotes.
