Is there any way to dynamically choose the interpreter that's executing a script? I have a script that I'm running on two different systems, and the interpreter I want to use is located in different locations on the two systems. What I end up having to to is change the hashbang line every time I switch over. I would like to do something that is the logical equivalent of this (I realize that this exact construct is impossible):
if running on system A: #!/path/to/python/on/systemA elif running on system B: #!/path/on/systemB #Rest of script goes here
Or even better would be this, so that it tries to use the first interpreter, and if it doesn't find it uses the second:
try: #!/path/to/python/on/systemA except: #!path/on/systemB #Rest of script goes here
Obviously, I can instead execute it as
depending on where I am, but I actually have a wrapper script that launches
myscript.py, so I would like to specify the path to the python interpreter programmatically rather than by hand.
