Column ordering is not preserved

[amirouche]

At least before Python 3.7 column ordering is not kept. I am new to the field of data science and data engineering. I am wondering whether column order is significant in a table.

WDYT?

Hi @amirouche, dictionary order is considered an implementation detail and not relevant for most use cases. If you require a specific order, you can use collections.OrderedDict.

records = [{'a': 1, 'b': 2}, {'a': 3, 'b': 4}]
[OrderedDict(sorted(r.items(), key=lambda t: t[0])) for r in records]
