there are two new commands: Import module (F5) imports or reloads the module and also adds its name to the __main__ namespace. This gets executed in the PyShell window under control of its debug settings. Run script (Control-F5) is similar but executes the contents of the file directly in the __main__ namespace.

"""Extension to execute code outside the Python shell window.
|
|
|
|
This adds two commands (to the Edit menu, until there's a separate
|
|
Python menu):
|
|
|
|
- Import module (F5) is equivalent to either import or reload of the
|
|
current module. The window must have been saved previously. The
|
|
module is added to sys.modules, and is also added to the __main__
|
|
namespace. Output goes to the shell window.
|
|
|
|
- Run module (Control-F5) does the same but executes the module's
|
|
code in the __main__ namespace.
