#!/usr/bin/python vals = [1, 2, 3, 4] vals.insert(0, -1) vals.insert(1, 0) vals.insert(len(vals), 5) print(vals) In the example, we insert three new elements to a list. vals.insert(0, -1) We insert the -1 value
I think that's a bit clunky and confusing to read. Instead, I propose something like the following: Counter(my_iterable).most_common_value() This would return the most frequently occurring element in the list (picking an arbitrary value or maybe the first that appears in case of a tie)....

return f.getvalue() f1 = StringIO("booh+") print foo(f1) # prints "booh+hello" What if a cStringIO instance were passed? There are technical reasons why cStringIO can't or shouldn't inherit from StringIO, but more importantly, requiring inheritance defeats Python's reliance onduck typing...
Python hack (at best) here... I would like to base a selection on an already selected record in a layer, and can't quite seem to crack that nut. Here is the pseudo code: Select a record ' in this case a point Extract the FullStreet attribute value ' it'll be something like S ...
