How do I find a module or application to perform task X?
Check the Library Reference to see if there’s a relevant standard library module. (Eventually you’ll learn what’s in the standard library and will able to skip this step.)
Search the Python Package Index.
Next, check the Vaults of Parnassus, an older index of packages.
Finally, try Google or other Web search engine. Searching for “Python” plus a keyword or two for your topic of interest will usually find something helpful.
If you still cannot find what you’re looking for, try asking on a public forum.
