package_script

Package a script together with all its dependencies.

For example, on a remote computer I know for a fact that numpy and scipy are available, but I cannot or cannot easily gaurantee that module x will be installed. I want to run script MyScript.py on this remote machine, but it depends on module x. package_script() will recurse through MyScript.py and prepend module x (and all of module x’s dependencies down to numpy, scipy, and default python modules, assuming I’ve set existing_modules=[‘numpy’, ‘scipy’]).

mr_utils.utils.package_script.get_imports(filename, existing_modules=None)

Removes import statements and gets filenames of where imports are.

mr_utils.utils.package_script.get_std_lib()

Get list of all Python standard library modules.

mr_utils.utils.package_script.package_script(filename, existing_modules=None)

Package a script together with all dependencies.

Parameters:

• filename (str) – Path to Python script we wish to package.
• existing_modules (list, optional) – List of terminating modules.

Returns:

Bundled python script with only existing_modules dependencies.

Return type:

str

Notes

“Terminating module” is a module we assume is available on the machine we want to run the packaged script on. These are python’s built-in modules plus all existing_modules specified by caller.
