And I like subset idea.But regarding 'pythonic'.... if we look at the the code provided then generator expression has also nested for-loop (albeit on one row) and character count is not in line with 'Limit all lines to a maximum of 79 characters.'. So, how should one judge this code from perspective of being 'pythonic'... . Applying 'pythonic' convention to tackle long line ('Continuation lines should align wrapped elements either vertically using Python's implicit line joining inside parentheses, brackets and braces, or using a hanging indent'): def filter_dicts(data, *args, **kwargs): return ({key: row[key] for key in args} for row in data if row.items() >= kwargs.items())and as OP already mentioned, these codes are not equal as give different results with different datasets. You know, all that stuff regarding errors passed silently. |
