Is there a Python library that shows execution time per line?

Question

I have found this library called heartrate which shows how many times each line has been hit. I'm wondering if there is a similar library that can show the execution time of each line? Sometimes a single line can be a bottleneck of a program.

Answer 1

There is a library called pyheat.

you can install by

pip install py-heat

and import it using from pyheat import PyHeat

Pyheat can be used to generate a heatmap of time numbers for each line of code for a Python module. Pass the path of the Python file as a parameter to the PyHeat function.

ph = PyHeat('merge_sort.py')  # mergesort.py is the example given
ph.create_heatmap()
ph.show_heatmap()
