|I am finding myself often doing for loops over a subset of a list, like:
|
| for r in results:
| if r.numNodes != numNodes:
| continue
| # do something with r
Why write it backwards?
for r in results:
if r.numNodes == numNodes
# do something with r
is the direct parallel with the below code.
| It would be nice if the plain for loop was as flexible as list
| comprehensions and allowed an optional if clause, like this:
|
| for r in results if r.numNodes == numNodes:
| # do something with r
Same as above with ':\n' deleted. A trivial difference.
An optional if clause is *less* flexible than an optional if statement and
block.

Yes, and Guido rejected at that time.
