thank you for the reminder. But after reading it, I was left with a
question. Why the new syntax for what appears to be nothing more than a
different way of expressing nested for loops? at first I tried
rearranging the one of the examples from the previously referenced
document to clarify (in my mind) what was going on:
[x*y
for x in vec1
for y in vec2
]
then when I tried to rewrite it as a nested for loop, that's when I
realized list comprehensions is a method of returning the calculation in
the interior of a for loop as an assignment without requiring
aggregation of results in a temporary variable.
so a double thank you to you because you've clarified something that has
been a mystery to me for awhile.
now if I could find someone to explain distutils and eggs so that I
understand that as well... ;-) Heck, I would even settle for a wizard
tool generating the first approximation for me.
