A Python interface to x3270, an IBM 3270 terminal emulator
py3270 is a Python interface to x3270, an IBM 3270 terminal emulator. It provides an API to a x3270 or s3270 subprocess.
The x3270 executables need to be on your PATH!
A brief example of usage:
from py3270 import Emulator # use x3270 so you can see what is going on em = Emulator(visible=True) # or not (uses s3270) em = Emulator() em.connect('3270host.example.com') em.fill_field(17, 23, 'mylogin', 8) em.fill_field(18, 23, 'mypass', 8) em.send_enter() # if your host unlocks the keyboard before truly being ready you can use: em.wait_for_field() # maybe look for a status message if not em.string_found(1, 2, 'login succesful'): abort() # do something useful # disconnect from host and kill subprocess em.terminate()
None, sorry. Read the code, its pretty simple & self-explanatory :)

Upgrading from 0.1.x to 0.2.0
There are some backwards incompatable changes from 0.1.5 to 0.2.0. Namely:
- x3270 executables now need to be on the PATH
- Don’t use x3270.EmulatorBase, use x3270.Emulator instead. Its the same API exect that you no longer need to specify the paths to the x3270 executables.
- the underlying Command object and some internal APIs have changed. If you were digging into the Emulator instance to change things, you may have problems. See the source, the changes weren’t major and shouldn’t be too hard to fix.

The interface seems sound, but the Emulator class has only basic functionality. There are more x3270 commands that the Emulator could have methods for. That being said, I believe most x3270 functionality can be supported at a lower-level by the use of Emulator.exec_command().
The py3270 tip is installable via easy_install with easy_install py3270==dev.
