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?

The standard approach is to copy the file to the unix machine and use
the dos2unix command.

check if there is an option like in Geany to select encoding and line
endings

In gvim, type:

:se ff=unix

then resave the file. Once it's in unix format, gvim won't change it
back to dos unless you tell it to.
