tests/cpydiff: Add initial set of tests for uPy-CPython differences. These tests are intended to fail, as they provide a programatic record of differences between uPy and CPython. They also contain a special comment at the start of the file which has meta-data describing the difference, including known causes and known workarounds. 2017-02-06 23:55:37 -05:00			`"""`

tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting. 2020-03-22 22:26:08 -04:00
