modsys: Add basic sys.exc_info() implementation. The implementation is very basic and non-compliant and provided solely for CPython compatibility. The function itself is bad Python2 heritage, its usage is discouraged. 2015-04-24 20:17:41 -04:00			`import sys`
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

vm: On exiting except block, clear sys.exc_info() value. This doesn't handle case fo enclosed except blocks, but once again, sys.exc_info() support is a workaround for software which uses it instead of properly catching exceptions via variable in except clause. 2015-04-25 18:20:49 -04:00			`# Outside except block, sys.exc_info() should be back to None's`
