Hello,
The other day I needed to pack a dictionary, the value of each key was a list.
In the code I was packing the list and the dictionary at the same time. First I
tried something like this:
list = []
dict = {}
x = 1
dict['int'] = list.append(x)
The result was {'int': None}. Why is the valu
Okay,
So how would you break out from this situation?

Okay,
I'm not sure if this is good practice, but I could assign a variable within the
while loop, that is assigned something that will then break the outer loop.
while True:
breakout = True
for i in items:
if i > 10:
breakout = False

Okay,
Thanks guys.
That explains it.

as i mentioned in my other msg, you need another break statement that
is *not* in another loop. in your case, not in the for-loop. you need
a break statement somewhere within your while block (again, that's not
in any other loop). IOW, it should be

Hi everyone,
Thanks for the comments Dave and Alan!
Based on these I have updated the code... I don't know if this is more
readable.
@Dave: I kept the original separate and combine function with bases as I
thought I would move them to a math library if I need to work in other
bases, however now

It sounds like this is not the first assignment in the course. True?

Hi,
Does anyone know how to do a unittest assert for a type?
So If you have a program returning a Decimal, lets say Decimal("1"), and you
want to make sure that what is returned is a Decimal object.
At first I thought of importing Decimal and making my own Decimal("1") and

Okay,
Thanks that worked.
I still needed to import the Decimal class and I'm not sure that is okay. The
reason why is I'm receiving the Decimal value from another program, if I
already know that the value will be a Decimal why test it?
Perhaps I'm getting to caught up in this test-driven deve

When possible, it's better to use assertEqual() rather than a plain

Hi,
Thanks for all the comments so far.
DaveA, I'm receiving the value via pyODBC, after running a query on a database.
The test is to first make sure the value is a Decimal (pyODBC returns a Decimal
object if what is coming from the database is a decimal type). So if I don't
have a value that
