tests: Add tests for SyntaxError, TypeError, and other missing things. This is intended to improve coverage of the test suite.

# make sure syntax error works correctly for bad const definition
tests: Add test for micropython const feature when it has a SyntaxError.
2015-03-01 07:06:24 -05:00
py/modmicropython: Add micropython.const, alias for identity function. Having a micropython.const identity function, and writing "from micropython import const" at the start of scripts that use the const feature, allows to write scripts which are compatible with CPython, and with uPy builds that don't include const optimisation. This patch adds such a function and updates the tests to do the import.

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.

py/parse: Remove unnecessary check in const folding for ** operator. In this part of the code there is no way to get the ** operator, so no need to check for it. This commit also adds tests for this, and other related, invalid const operations.

# these operations are not supported within const
test_syntax("A = const(1 @ 2)")

py/parse: Support constant folding of power operator for integers. Constant expression like "2 ** 3" will now be folded, and the special form "X = const(2 ** 3)" will now compile because the argument to the const is now a constant. Fixes issue #5865.
