Answer 1

Here's a link to the non standard libraries. random is part of the standard library.

matplotlib

scipy

networkX

numpy (reuired by scipy)

Answer 2

1. 'random' is shipped with the standard library
2. pylab and scipy are part of SciPy
3. Networkx is available here

Answer 3

random is a standard python library module, no need to install that.

pylab and scipy can be found on the SciPy site

networkx also has a site

BTW: These are all easily found using google.com

Answer 4

When installing Scipy, you also need to install numpy which it depends on. See here. You are getting the error because numpy is not installed on your system.
