   • fun()
   • mod‑>fun()

3. A function returning a list of all entities available in a module is called:

   • content()
   • dir()
   • entities()
   • listmodule()

4. The pyc file contains:

   • compiled Python code

5. When a module is imported, its contents:

   • are executed once (implicitly)
   • are executed as many times as they are imported
   • are ignored
   • may be executed (explicitly)

6. A predefined Python variable, storing the current module name, is called:

   • __modname__
   • __name__
   • __mod__
   • __module__

7. The following statement:

   from a.b import c

   causes the import of:

   • entity c from module b from package a
   • entity a from module b from package c
   • entity c from module a from package b
   • entity b from module a from package c

8. Entering the try: block implies that:

   • the block will be omitted
