1 :mod:`!tracemalloc` --- Trace memory allocations

13 The tracemalloc module is a debug tool to trace memory blocks allocated by
23 variable to ``1``, or by using :option:`-X` ``tracemalloc`` command line
24 option. The :func:`tracemalloc.start` function can be called at runtime to
30 :option:`-X` ``tracemalloc=25`` command line option.
