Examples

Create a series with dict type data.

>>> import maxframe.dataframe as md
>>> import pyarrow as pa
>>> from maxframe.lib.dtypes_extension import dict_
>>> s = md.Series(
...     data=[[("k1", 1), ("k2", 2)], [("k1", 3)], None],
...     index=[1, 2, 3],
...     dtype=map_(pa.string(), pa.int64()),
... )
>>> s.execute()
1    [('k1', 1), ('k2', 2)]
2               [('k1', 3)]
3                      <NA>
dtype: map<string, int64>[pyarrow]

>>> s.dict["k2"] = 4
>>> s.execute()
1    [('k1', 1), ('k2', 4)]
2    [('k1', 3), ('k2', 4)]
3                      <NA>
dtype: map<string, int64>[pyarrow]
