tests/micropython: Add some tests for failed heap allocation. This adds tests for some locations in the code where a memory allocation should raise an exception. 2019-04-18 14:34:12 +10:00			`# test handling of failed heap allocation with dict`

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 21:26:08 -05:00			`{x: x}`
