Let's suppose I want to create a list of n functions of a single argument, returning the sum between argument and index in the list, so that e.g.:
f[0](10) will return 10 f[3](12) will return 15 ...and so on. I had naively though of coding: f = [lambda x: x+j for j in range(n)] Unfortunately, each function in the list f[]() behaves as a closure, and f[k](p) does NOT return p+k but p+j (for whatever value j has at the moment: typically n, the last value assumed by j in the list comprehension loop). Is there a way of achieving my goal? (Of course, n is not a constant known in advance, so I can't manually unroll the loop.) Thanks for any suggestion. -- http://mail.python.org/mailman/listinfo/python-list
