I want to import a plain text file, no matter the extension cause I want to use my own, as a module in python.

For example. I have the strings for my program in separated .py files, and, depending on what language is selected, I import one file or the other.

Everything works well with this, but, I want to make this file, apparently not readable for a common user, so, I want to give them a custom extension that any of the programs installed can't read. But, due that import only work with .py files, I want to know if there is a way to do this with other file types. Or if is it another way to do something like this.

Thank you.

maybe read file sources and use eval method?

You may use it as

def import_module(filename):
    with open(filename, 'r') as file:
        file_contents = file.read()
    module_object =  exec(file_contents)
    return module_object

But that variant are not secure!

And such question was in stackoverflow read it

  • Ok, this works as expected, but, why this isn't secure? – David González Blazman Jan 14 '19 at 12:24

    Because, maybe that file will be replaced with file with some code for getting remote access to computer wich execute your program – Crazy Jan 14 '19 at 12:28

    as another variant (such insecure), you may compile your code into some variable in code, and write it as pickled file in working directory – Crazy Jan 14 '19 at 12:30
  • @DavidGonzálezBlazman, make my answer as right if it helps your – Crazy Jan 14 '19 at 12:34
  • Ok, I have this file encoded and with control words to make sure this is the correct file so I can use exec properly secured. Thanks! – David González Blazman Jan 14 '19 at 12:53
  • Note: This answer doesn't work, in-so-far as it's not equivalent to `import` or `importlib.import_module` since it doesn't import any of the imports present within the module... :/ – George Jul 01 '21 at 21:58
