Yes but:
a = [] for i in range(10): ... a.append(lambda: i) ... print [x() for x in a] [9, 9, 9, 9, 9, 9, 9, 9, 9, 9]
This subtle semantic of lambda is quite confusing, and still forces people to use the "i=i" trick.
The 'subtle sematic' had nothing to do with lambda but with Python functions. The above is exactly equivalent (except the different .funcname) to a = [] for i in range(10): def f(): return i a.append(f) del f That should be equally confusing (or not), and equally requires the 'i=i' trick (or not). As is, either function definitiion is a constant and the loop makes useless duplicates. Either form would have the same effect is hoisted out of the loop. Terry Jan Reedy
