The file selected by the above constructor must have been created by theĬorresponding version of profile or cProfile. Will be printed to the stream specified by stream. This class constructor creates an instance of a “statistics object” from aįilename (or list of filenames) or from a Profile instance. Stats ( *filenames or profile, stream=sys.stdout ) ¶ via a sys.exit() callĭuring the called command/function execution) no profiling results will beĪnalysis of the profiler data is done using the Stats class. Note that profiling will only work if the called command/function actually Profile the cmd via exec() with the specified global and Write the results of the current profile to filename. print_stats ( sort = - 1 ) ¶Ĭreate a Stats object based on the current Stop collecting profiling data and record the results internallyĪs the current profile.

Instead of printing the output at the end of the profile run, you can save the Not recurse, these two values are the same, and only the single figure is
