Hello,
Not really specific to Python or matplotlib (but that's what I'm
using). I'm looking for a good combination of colours and symbols for
scatter plots, and combination of colours and line styles for line
plots. Too often I find myself producing these when I don't know whether
they will e

Hello,
I have generator code along the following lines,
Q = queue.Queue()
Q.put(x)
while not Q.empty():
x = Q.get()
if :
yield x
else:
Q.put()
If I change it to,
Q = []
Q.append(x)
for x in Q:
if :
yield x
else:
Q.append()
then it runs a

Hello,
I have a class I wrote for Python2 that needs to be made to work
on Python3. On Python2 it inherited from long, so it needs to inherit
from int on Python3. The following works, but I'm not sure it's the
cleanest solution. It's the first time I've wanted / needed to make a
parent class
