New submission from Dave E <david.elzi...@gmail.com>: I might be missing something, but I am expecting the following code to print out a list of lists with each internal list holding one number[0-4], but instead the internal lists are a copy of the list "count".
#!/usr/bin/python count = range(4) twoDimensionList = [[]] * len(count) for i in range(len(count)): twoDimensionList[i].append(count[i]) print twoDimensionList Should print: [[0], [1], [2], [3]] but erroneously prints: [[0, 1, 2, 3], [0, 1, 2, 3], [0, 1, 2, 3], [0, 1, 2, 3]] ---------- files: twoDimensionalList.py messages: 152450 nosy: drathlian priority: normal severity: normal status: open title: making assignments to an empty two dimensional list type: behavior versions: Python 2.7 Added file: http://bugs.python.org/file24390/twoDimensionalList.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13925> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
