How to search help using python console

Question

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.

Answer 1

The pydoc -k flag searches the documentation.

pydoc -k 
    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
