tests: Rename "array" module to "uarray". 2019-10-22 02:33:23 -04:00			`import uarray as array`
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
