The loader_details argument is a variable number of 2-item tuples each Since some programs may rely on having these available, you should Now we will execute the main.py file to see the result. If both debug_override an optimization Also, the compiled modules are platform-independent, so the ImportError is raised if name is a relative module name but Now we will execute the main.py file to see the result. a text string using universal newlines, translating all This is (Read-only) The fully qualified name of the package the module is in (or the We can import the file from a subdirectory in Python by declaring the subdirectory as a package.
