[FIXED] How to convert DatetimeArray to list?

Issue

I'm trying to convert DatetimeArray instance arr to list. I've tried arr.to_list(), which gives:

'DatetimeArray' object has no attribute 'tolist'

The higher level outcome I'm trying to achieve is, I have this df with a column dt that are pandas timestamps. I want to get a list (or anything I can iterate over) of the unique df.dt, and also prepend to that list another timestamp another_dt.

Solution

Did you try list():

dta = pd.arrays.DatetimeArray(pd.DatetimeIndex(['2023-01-01', '2023-01-02']), freq='D')
print(list(dta))

# Output
[Timestamp('2023-01-01 00:00:00'), Timestamp('2023-01-02 00:00:00')]
