ValueError: insecure pickle string

[pradeepbpin]

I am encountering 'Value Error: insecure string pickle' when trying to
execute the script on Ubuntu. The same script and the pickled file
works without any problem in Windows. For working in Ubuntu I just
copied both the script file and pickled file from Windows.


How can I get out of this error? Rather, I would like to have common
script and pickled file that can work platform independently.

Writing and reading the pickled file in binary mode seems to be
working. Thank you.

Return Values & lambda

[pradeepbpin]

I have a main program module that invokes an input dialog box via  a
menu item. Now, the code for drawing and processing the input of
dialog box is in another module, say 'dialogs.py'. I connect the menu
item to this dialog box by a statement like,

manu_item.connect('activate', lambda a: dialogs.open_dilaog())

If this function open_dialog() returns a list of dialog inputs values,
how can I access those values in the main module ?

Thanks to all.

Hashbang error

[pradeepbpin]

I use gVim as an editor to create python scripts on a windows machine.
To run the same script on my ubuntu machine, I added a hashbang line
to the script. Now when I run this script from command line of ubuntu,
I get a bad interpreter error, like below

/usr/bin/python^M: bad interpreter: No such file or directory

This, I understand, is due to the interpretation of newline character
at the end of the hashbang.

I have checked and found out that this does not happen if I create the
script in Ubuntu with gVim.

Now, how can I avoid this error when I create the script on a windows
machine?

In my opinion, pydoc would be a good choice. I am a fan of it.
