问题 I was testing a fix using pdb.set_trace() to make sure it worked the way I expected before implementing it and kept getting a weird error. (Pdb) test = [1,2,3,4,4,3,2,1] (Pdb) max(range(len(test)),key=lambda i: test[i]) *** NameError: global name 'test' is not defined So I moved to my localmachine to make sure I could reproduce as simply as possible before asking for help. In ipython I get the exact same behavior. In [1]: test = [1,2,3,4,4,3,2,1] In [2]: max(range(len(test)),key=lambda i:
