How to search help using python console

python help string
python help() function
python help operator
functions help in python
python help statement
how to check methods in python
help input python
python idle help

Is there any way to search for a particular package/function using keywords in the Python console?

For example, I may want to search "pdf" for pdf related tasks.


The pydoc -k flag searches the documentation.

pydoc -k <keyword>
    Search for a keyword in the synopsis lines of all available modules.

From a terminal, run..

$ pydoc -k pdf

..for example:

$ pydoc -k pdf
PdfImagePlugin 
wx.lib.pdfwin 
PIL.PdfImagePlugin

It doesn't search the contents of the documentation, but it searches all module names - if that's not enough, I'd suggest using Google or StackOverflow to search for "Python PDF module" or similar

Python help() function, How do you check if a function is in Python? Try this working fine (tested in python 2.7) Tkininter comes with the columnspan argument to span the labels Django 1.0 was updated recently Syntax : list. count (value) Code: colors = ['red', 'green',


You can use help to access the docstrings of the different modules you have imported, e.g., try the following:

help(math)

and you'll get an error,

import math
help(math)

and you will get a list of the available methods in the module, but only AFTER you have imported it. It also works with individual functions, e.g. after importing math try:

help(math.sin)

To deal with pdf you will probably have to install a third party module. A quick search has led me to this result, which I haven't tried:

http://www.devshed.com/c/a/Python/Python-for-PDF-Generation/

Validate Arguments Passed to a Function, using the __doc__ method of the object or using the help function. If no argument is passed, Python's help utility (interactive help system) starts on the console. >>> help() Then, you can enter the name of the topic to get help on writing Python programs and using Python modules. For example: help> True help> 'print' help > print. To quit the help utility and return to the interpreter, you need to type quit and press enter. help > quit


help( "modules")

>>> help( "modules" )

Please wait a moment while I gather a list of all available modules...
