Pandas DataFrame.at_time(~) method extracts rows that are of the specified time of day.
Parameters
1. time | string or datetime.time
The time of day.
2. axis | int or string | optional
By default, axis=0. Due to a lack of documentation, we're not too sure how this parameter can be used. If you have some insight, we'd love to chat with you!
Return Value
A DataFrame containing all the rows that are of the specified time of day.
Examples
Consider the following DataFrame:
index_date = pd.date_range("2020-12-25", periods=3, freq="12H")df = pd.DataFrame({"A":["a","b","c"]}, index=index_date)df
A2020-12-25 00:00:00 a2020-12-25 12:00:00 b2020-12-26 00:00:00 c

To fetch all rows where the time of day is "00:00" (i.e. midnight):
df.at_time("00:00")
A2020-12-25 a2020-12-26 c
Here, the return type is a DataFrame.
