Hello, I've knocked together a quick proof-of-concept that allows type annotations to be automatically added to Python source code by running it:
https://github.com/mwilliamson/farthing As the code, such as a test suite, runs, the types of arguments and return values (for functions in the file/directory to be annotated) are stored. After the code has finished, appropriate annotations are added. (There's a tiny example in the README.rst in case that makes things a little clearer.) At the moment, this is just a small prototype that I've cobbled together. I was curious if anybody knows if anybody else has done anything similar? Thanks Michael -- https://mail.python.org/mailman/listinfo/python-list
