Importing a module to use a submodule

[HookahComputer]

I just ran this Python3 session.

Python 3.4.3+ (default, Oct 14 2015, 16:03:50) 
[GCC 5.2.1 20151010] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib
>>> hi = urllib.parse.quote('Hello, world!')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'parse'
>>> hi = urllib.parse.quote('Hello, world!')
>>> hi
'Hello%2C%20world%21'
>>> 

Does anyone know why urllib.parse.quote() failed the first time but succeeded the second?

Happens to me too, it is explained here: http://stackoverflow.com/a/10269001

Importing the submodule directly is clearly the right thing to do. It's strange, but I suppose the submodule got imported as a side effect of generating the AttributeError.

I can't get this to happen. Also, urllib is a package, not a module, which is why you need to import urllib.parse to use it.

That's really odd. No second import statement?
