A lot of Python packages are only available as source code.
To install such a Python package, use its
$ sudo python setup.py install
This will install the Python files to a central location such as
/usr/local/lib. If you do not have such permissions or want to install to a user-local location then try this:
- Create a directory, say
/home/joe/python_libs/lib/python in your home directory to host local Python packages.
- Set the above path in the
PYTHONPATH environment variable.
- Install the package by passing the above path to the
$ python setup.py install --home /home/joe/python_libs
To uninstall a package is tricky.
One solution is to find out where the files were installed and then use that list to remove those files:
$ sudo python setup.py install --record install-files.txt
$ cat install-files.txt | sudo xargs rm -rf
Another solution is to just locate the installation directory, like
/usr/local/lib/python2.7/dist-packages for example and delete the directory of the package.

To list all the installed programs at the commandline in Windows, use this command:
A lot of parameters are listed for every product. Some of the parameters are: name, description, URL, telephone number (not kidding!), ID, installed date, installed directory, source directory from which it was installed, language, name of installer file, vendor and version.
With so many parameters, the output for each prorgram simply cannot fit on a single line. So, it is better to redirect it to a file:
wmic product > proglist.txt
Tried with: Windows 7 x64
Installing a package from the Ubuntu repositories is easy. There are three ways to do it.
You can use the Ubuntu Software Center. Open it, search for the package name and install it.
You can use the Synaptic program. You may have to install it, if it is not already there. Open it, search the package name, mark it for installation and choose Apply.
If you like the terminal, use the apt-get program. For example, to install a package named Foo:
$ sudo apt-get install Foo
Tried with: Ubuntu 12.04.1 LTS
