Hello,
I am hope that pandas questions are OK here.
In a panda lecture, I did not get the expected result.
I tried this on two different platforms
(old macOS distro and up-to-date Ubuntu Linux distro, 22.04)
The Linux distro has:
python 3.10.11
pandas 1.5.2
conda 23.3.1
Is this double bracket form, df[[1]], deprecated... maybe?
There is data in a dataframe, df.
>>> subset = df[[1]]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/home/dks/anaconda3/lib/python3.10/site-packages/pandas/core/frame.py",
line 3811, in __getitem__
indexer = self.columns._get_indexer_strict(key, "columns")[1]
File
"/home/dks/anaconda3/lib/python3.10/site-packages/pandas/core/indexes/base.py",
line 6113, in _get_indexer_strict
self._raise_if_missing(keyarr, indexer, axis_name)
File
"/home/dks/anaconda3/lib/python3.10/site-packages/pandas/core/indexes/base.py",
line 6173, in _raise_if_missing
raise KeyError(f"None of [{key}] are in the [{axis_name}]")
KeyError: "None of [Int64Index([1], dtype='int64')] are in the [columns]"
What could be making this fail?
Thank you!
