How can I execute Python code without Komodo -ide?

I do that without the IDE:

$ ipython
$ edit file.py
$ :x (save and close)

It executes Python code, but not the one, where I use Pygame. It gives:

WARNING: Failure executing file:

In the IDE, my code executes.

From stackoverflow

• If something doesn't work in ipython, try the real Python interpreter (just python); ipython has known bugs, and not infrequently code known to work in the real interpreter fails there.

  On UNIXlike platforms, your script should start with a shebang -- that is, a line like the following:

  #!/usr/bin/env python
  

  should be the very first line (and should have a standard UNIX line ending). This tells the operating system to execute your code with the first python interpreter found in the PATH, presuming that your script has executable permission set and is invoked as a program.

  The other option is to start the program manually -- as per the following example:

  $ python yourprogram.py
  

  ...or, to use a specific version of the interpreter (if more than one is installed):

  $ python2.5 yourprogram.py
