If you really want to, you can pass a *single* argument in your #! line,
e.g.:
#!/usr/bin/python3 -Wd
This works for options that can be grouped into a single argument.
Multiple -X options aren't supported, nor is combining a -X option
with other options.
Using a shebang also works in Windows if .py files are associated with
the py.exe launcher, which can handle multiple arguments in the
shebang instead of just one.
And as an additional alternative, when I want something weird (extra python
args or the like) I usually make my script.py into a module and invoke it via a
shell script, eg:
#!/bin/sh
exec /particular/python python-opts... -m script_module ${1+"$@"}
Obviously that'd need a little adaption under Windows.
This has a few advantages:
- you can use several python-opts
- your script, unless very trivial, will usually have some reusable pieces;
by making it a module with a main() function you can make those pieces
available for _other_ modules to import and use!
Making your script a module may seem like some extra effort to little benefit,
but after you've done it a few times it is easy and I at least now have a suite
of little modules whose components get reused all the time.
