New submission from Jeong-Min Lee:

Running the Pretty top example (http://docs.python.org/dev/library/tracemalloc.html#pretty-top) in the tracemalloc module documentation causes a ValueError.

    Traceback (most recent call last):
      File "t.py", line 32, in <module>
        display_top(snapshot, 10)
      File "t.py", line 9, in display_top
        top_stats = snapshot.statistics(group_by)
      File "/home/falsetru/h/cpython/Lib/tracemalloc.py", line 449, in statistics
        grouped = self._group_by(key_type, cumulative)
      File "/home/falsetru/h/cpython/Lib/tracemalloc.py", line 395, in _group_by
        raise ValueError("unknown key_type: %r" % (key_type,))
    ValueError: unknown key_type: 10

The last line of the example should be:

    display_top(snapshot, limit=10)
