I could do this:
from ftplib import FTP
ftp = FTP('ip_address', 'username', 'password')
Or, I could do this:
ftp = FTP('ip_address')
ftp.login('username', 'password')
Most of the examples I am seeing online use the second approach. Is
there some reason why this is to be preferred?
TIA!

Isn't this just argument unpacking? Thus the necessary "*".

I am trying to wrap my head around the mechanics of inheritance in
Python 3. I thought that all attributes of a superclass were
accessible to an instance of a subclass. But when I try the
following:
py3: class A:
... def __init__(self):
... self.aa = 'class A'
...
py3: class B(A)

Thank you to everyone that provided illumination in this thread!
Things seem much clearer now, which caused me to realize that what I
wrote below cannot work as written (Even though I did copy and paste
it from the interpreter):

I had briefly looked at Kahn Academy quite a while back, but it did
not seem (at that time) to have what I needed.

Traceback (most recent call last):

10
It is apparent that int() does not like strings with floating-point
formats. None of my books (as far as my flipping can tell) or the
below built-in

I was expecting int("10.5") to return 10 .

At my workplace we have nearly completed the hardware and software
upgrades. Up to this point I have been using Perl to write scripts
that work with our planning software which has its own proprietary
scripting environment. Generally speaking the scripts I write are
always text files which run Sola

In my on again, off again studies of Python I am stumped on something
that ought to be trivial, but I am not seeing it. When I run this
program (only the part up to where the error occurs is shown):

numberToGuess = random.randint(1, 20)
numberOfGuesses = 0
