I read that pressing shift+tab after a function displays the function's docstring in an IPython notebook, but this does not seem to work in my IPython (no notebook). I run IPython 4.0.0 on Ubuntu.
Any suggestion?

Effective Ways to Pass Parameters to Python Functions 1. Positional argument. The order in which arguments are passed matters. Function when called matches the order in which... 2. Keyword argument. The argument passed is name-value pair. The order in which arguments are passed doesn't really... 3. ...
Arguments are often shortened to args in Python documentations. Parameters or Arguments? The terms parameter and argument can be used for the same thing: information that are passed into a function. A parameter is the variable listed inside the parentheses in the function definition.
In the above program, a and b are the formal parameters. In python, the actual parameters are also known as Arguments. The arguments are the data or objects specified during a function call. It passes the data to the function where the formal parameters capture the data and copies into them.
In Python, when we define functions with default values for certain parameters, it is said to have its arguments set as an option for the user. Users can either pass their values or can pretend the function to use theirs default values which are specified.
The standard (console) IPython does not support the call tips via <shift> + <tab>. But a question mark before or after the function shows you the docstring:
In [1]: list.index?
Docstring:
L.index(value, [start, [stop]]) -> integer -- return first index of value.
Raises ValueError if the value is not present.
Type: method_descriptor
As an alternative you can use the qtconsole version:
ipython qtconsole
Then:
In [1]: list.index(
Should show you a box with a call tip without pressing <shift> + <tab>:

Press Tab+Shift, it works for jupyter notebook 5.6.0 version.
