frmglobals = func.__globals__.copy()
func.__globals__.update(localArgs) ret= func(*args, **kwargs) func.__globals__.clear() func.__globals__.update(frmglobals)
with this one:
with _modifyGlobals(func.__globals__, localArgs): ret = func(*args, **kwargs)
with _modifyGlobals defined as:
from contextlib import contextmanager
@contextmanager def _modifyGlobals(glbls, additions): frmglbls = glbls.copy() try: glbls.update(additions) yield finally: glbls.clear() glbls.update(frmglbls)
Posting code with all the '>>>' prompts added makes it terribly hard to cut and paste to try it out.
