I checked out a SVN repository, and tried to python on my Ubuntu 10.04 terminal, which is a Python script, but I get the following error:

abc@def:~/Downloads/a-read-only$ python  
usage: [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]  
   or: --help [cmd1 cmd2 ...]  
   or: --help-commands  
   or: cmd --help

error: no commands supplied

I have no experience with Python, so any help I could get would be appreciated.

looks like you need to add a "cmd1".
to find out what that is, type

python --help

Well you could use terminal command to install python from Ubuntu. Try using:

sudo apt-get install python3

After Python has successfully installed. You could run the python terminal by typing 'python3' into the terminal and check if the command works. Or you could run the python scripts using:
