Hi guys, it's been a while since I posted and I've learned a lot since then.
Today I have a question on classes, I can't get mine to work.
class alist(list):
def __init__(self, b, a):
self = list()
self.append(b)
a = a + b
def appendit(self):
self.append(a)
print(alist(2,4))
[]
#It's blank

Welcome back. I'll try. First comment is that indentation ought to be
4 columns, until you have enough exper

Dave has already addressed many issues but there are a few more to consider

Thank you for reading this.
The recent question relating to classes has prompted to ask this one.
I have a main window class and a dialog class and they are defined in
separate files. I'm attempting to display the dialog when a menu item is
selected in the main window but it doesn't work becau

thinking that an import statement is needed in the main window class
referring to the dialog class. Import SatelliteListDialog isn't correct.

Hi all,
I'm having a doubt in the below program's 2n'd "for" loop.
>>> for n in range(2, 10):
... for x in range(2, n):
... if n % x == 0:
... print n, 'equals', x, '*', n/x
... break
... else:
... # loop fell through without finding a factor
...

So if SatelliteListDialog is defined in satellite.py you need
import satellite
in your main window file.
And satellite.py has to be in your library path too...

And this is the error message;

On its own, that is almost useless.
Python gives you more debugging information than that: it gives you a complete
traceback, which includes the actual line of code causing the prob

I believe Dave answered the OP's intended question.
