cProfile module provides a way to profile your code and measure the time spent in different functions. It doesn’t inherently have a built-in feature to limit the depth of the profiling, but you can achieve this by post-processing the profile results.
Here’s a step-by-step guide on how to limit the depth of profiling using
- Import the
cProfilemodule and profile your code:
import cProfile def your_function_to_profile(): # Your code here if __name__ == "__main__": profiler = cProfile.Profile() profiler.enable() your_function_to_profile() profiler.disable() profiler.print_stats(sort='cumulative')Code language: Python (python)
- Run your Python script.
- Save the profiling results to a file:
profiler.dump_stats('profile_results.prof')Code language: Python (python)
- Use the
pstatsmodule to post-process the profiling results and limit the depth:
import pstats # Load the profiling results profiler_stats = pstats.Stats('profile_results.prof') # Limit the depth to a specific level (e.g., 2) profiler_stats.strip_dirs().sort_stats('cumulative').print_stats(2)Code language: Python (python)
2 with the desired depth level you want to display in the profiling results. This will display only the top functions up to the specified depth level in terms of cumulative time.
By stripping directories and sorting the stats, you can focus on the functions that matter most for your analysis.’
Increasing the depth of cProfiler in Python to report more functions?
cProfile module in Python profiles your code to measure the time spent in functions. By default, it captures information for all functions called during program execution. If you want to increase the depth of profiling to report more functions, you don’t need to make any specific changes to
cProfile. It already captures data for all function calls. You can simply view the entire profile data by printing the statistics.
Here’s an example of how to use
cProfile to profile your code and view the entire profile:
import cProfile def function1(): # Function 1 code here def function2(): # Function 2 code here def main(): function1() function2() if __name__ == "__main__": cProfile.run("main()")Code language: Python (python)
In this example,
cProfile.run("main()") will profile the
main() function and all functions it calls (i.e.,
function2()), and it will print the statistics for all of them. There’s no need to set a specific depth;
cProfile automatically captures data for all functions in the call stack.
