You've asked several very vague questions. I would strongly recommend
that you read this:

http://www.catb.org/esr/faqs/smart-questions.html

Invoking wget can be done, but you may want to consider alternatives
such as doing the network request (HTTP, FTP, or whatever) directly in
Python. A one-line request that we do heaps of work for you is not the
best way to get results.

No but I can suggest some alternative ideas, such as using httplib
(built into python), or libcurl.  Or if you have to use wget, you run it
the same way you run any external command from python.  If it were my
I'd plunk a few search terms in google, such as "python run external
process."

Inherantly the python interpreter has a GC builtin 
to use pacakages like DLL by reference counting.

That almost makes sense. And it's almost profound, too.

Is the web broken where you are? If you google for "python wget", you 
will find example of how to call wget as an external process, as well as 
examples of downloading files from the web like wget would do but using 
only Python.

https://duckduckgo.com/?q=python%20wget


Or you could search for "python call external command" and then use wget 
as that external command.

For running any system command from Python, you can use the 
subprocess module:
  http://docs.python.org/3/library/subprocess.html#module-subprocess

To run "wget -p -k http://python.org" from Python you could
do something like this:

  import subprocess
  subprocess.call (['wget', '-p', '-k', 'http://python.org'])
