Python are global variables visible everywhere - correct answer ✔✔visible throughout the module but not outside the module Python how do you see the interpreter records names - correct answer ✔✔dir()

  • List names from the current module
  • dir(module) List names from an imported module Python what is name - correct answer ✔✔a string value that holds the name of the module If the module represents the "starting" module for the app, the name is actually set to "main What is init.py - correct answer ✔✔To indicate to the interpreter that the folders do in fact represent a package, each (sub)package must include a init.py file at the root level.
  • The file can in fact be empty
  • It can contain some package level initialization code that will be run the first time the package is accessed.
  • It can also contain a list of the modules that should be imported when the "from package import *" syntax is used, as indicated below. all = ["foo", "bar"]

Python does objects have their own variables - correct answer ✔✔So ANY changes made to a variable defined outside of the method definitions affects ALL such objects. Python what is init - correct answer ✔✔If init is present, it becomes the default constructor for an object. class Foo: x = 43 init(self): self.stuff = "stuff" get_x(self): print self. In this case, a new variable called stuff will be created and added to the object instance

  • If we instantiate n objects, each of the n objects will now have its own local version of stuff What about constructors - correct answer ✔✔one _init method per class (default) You can certainly add additional constructors.
  • However, these will use standard method syntax and naming conventions.
  • init1(), init2(), init_float()
  • You can also use method defaults to provide (or not provide) additonal arguments
  • init(self, person=None) Constructors can call other constructors
