How to get the current script's code in Python?


I want to get the current script as a string in a variable in Python.

I found two sub-optimal ways, but I hope there is a better solution. I found:

  1. The inspect import has a getsource method, but that only returns the code of one function (or class or whatever), but not the entire script. I can't find a way to pass the object of the entire script to getsource.

  2. I could find the file location of the script file using __file__ or sys.argv[0] and open it to read. But this seems too indirect to me.

So: is there a (better) way to access the entire script as a string?

If relevant: I'd prefer a Python 2.7 solution above a 3.x.


Solution

  • Try:

    import inspect
    import sys
    
    print inspect.getsource(sys.modules[__name__])
    

    Or even:

    import inspect
    import sys
    
    lines = inspect.getsourcelines(sys.modules[__name__])[0]
    
    for index, line in enumerate(lines):
        print "{:4d} {}".format(index + 1, line)
    

    The file the code is contained inside is considered to be a Python "module", and sys.modules[__name__] returns a reference to this module.

    Edit

    Or even, as @ilent2 suggested, like this, without the need of the sys module:

    import inspect
    
    print inspect.getsource(inspect.getmodule(inspect.currentframe()))
