Python cProfile Label [Explained]

You can use the cProfile module to profile the performance of your code and identify bottlenecks. To add labels to the profiling output, you can use the cProfile.run() function with the -s option. Here’s how you can do it:

import cProfile

def my_function():
    # Your code here

if __name__ == "__main__":
    label = "MyProfilingLabel"  # Replace with your desired label
    cProfile.run('my_function()', sort='cumulative', label=label)
Code language: Python (python)

In this example, you would replace my_function() with the code you want to profile. The cProfile.run() function is used to profile the my_function() and you can specify a label using the label parameter.

After running this script, you’ll get a profiling report that includes the specified label:

         4 function calls in 0.000 seconds

   Ordered by: cumulative time, descending

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1    0.000    0.000    0.000    0.000 {built-in method builtins.exec}
        1    0.000    0.000    0.000    0.000 <string>:1(<module>)
        1    0.000    0.000    0.000    0.000 your_script.py:4(my_function)
        1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler' objects}
Code language: Python (python)

In this output, you can see the label you specified in the filename:lineno(function) column, in this case, it would be "your_script.py:4(my_function)" with the label you set. This can help you identify which part of your code was profiled.

Remember to replace "your_script.py:4(my_function)" with the actual filename and line number where your function is defined in your code.
