How to use PYDOC

#Author: ManishHacker1


Hello everyone, Today my article is about Pydoc. Pydoc is a Python Documentation Tool which help we can search everything about Python Liabrary.


What is pydoc?



pydoc - the Python documentation tool

pydoc.py  ...
    Show text documentation on something.   may be the name of a
    Python keyword, topic, function, module, or package, or a dotted
    reference to a class or function within a module or module in a
    package.  If  contains a '\', it is used as the path to a
    Python source file to document. If name is 'keywords', 'topics',
    or 'modules', a listing of these things is displayed.

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

pydoc.py -p 
    Start an HTTP server on the given port on the local machine.  Port
    number 0 can be used to get an arbitrary unused port.

pydoc.py -g
    Pop up a graphical interface for finding and serving documentation.

pydoc.py -w  ...
    Write out the HTML documentation for a module to a file in the current
    directory.  If  contains a '\', it is treated as a filename; if
    it names a directory, documentation is written for all the contents.span>



How to Start:


You can use pydoc to search through the Python libraries installed on your system. At the command prompt type the following:



First open command prompt and go to your PATH where our pydoc.py is place.


C:\Users\hacked>cd\     and Hit Enter
C:\>cd Python27         and Hit Enter
C:\Python27\>cd Lib     and Hit Enter
C:\Python27\Lib\>python pydoc.py -g     and Hit Enter




Ok, Now you will see a pop up window which the following will appear:



Click on the open browser button then your browser will automatically start with the python document.
If you get an error and if you don't find your python document. .


Please check Tkinter package is installed in your system or not, If you have not this package in your system, then pydoc -g will return an error, since the graphics window that it opens requires Tkinter. An alternative is to start the web server directly:


C:\Users\hacked>cd\     and Hit Enter
C:\>cd Python27         and Hit Enter
C:\Python27\>cd Lib     and Hit Enter
C:\Python27\Lib\>python pydoc.py -p 7464


This starts the pydoc web server on port 7464. Now point your web browser at::


http://localhost:7464



and you will be able to browse the Python libraries installed on your system. Use this approach to start pydoc and take a look at the math module.

In this article we will use paramiko module to connect another machine. This is fully supported windows, Mac and Linux machine users. In this article, I will show you how to use Paramiko SSH (a Python SSH library) to connect and gather information from another Machine. What is Paramiko? Paramiko is a Python (2.6+, 3.3+) implementation of the SSHv2 protocol [1], providing both client and server functionality.
