How can I do profiling by line in Python 3? The standard profilers have only function-level precision.

The line_profiler test cases (found on GitHub) have an example of how to generate profile data from within a Python script. You have to wrap the function that you want to profile and then call the wrapper passing any desired function arguments. Also, you can add additional functions to be profiled as well.
line_profiler is a module for doing line-by-line profiling of functions. kernprof is a convenient script for running either line_profiler or the Python standard library's cProfile or profile modules, depending on what is available. They are available under a BSD license.
Python Profilers, like cProfile helps to find which part of the program or code takes more time to run. This article will walk you through the process of using cProfile module for extracting profiling data, using the pstats module to report it and snakeviz for visualization.
While line_profiler only works for Python 2.x, it doesn't seem too hard to make the necessary changes to get it to work with 3.x.
I've done this myself here. It's quick and dirty and pretty much untested, so use it at your peril, but it's possibly a start.

There's a nice Pull Request that implements Python 3 support very well
