python3-line-profiler - 4.2.0-1+b1 main

LineProfiler can be given functions to profile, and it will time the execution
of each individual line inside those functions. In a typical workflow, one
only cares about line timings of a few functions because wading through the
results of timing every single line of code would be overwhelming. However,
LineProfiler does need to be explicitly told what functions to profile.
.
If you are using IPython, there is an implementation of an %lprun magic
command which will let you specify functions to profile and a statement to
execute.
