python - How to remove the date information in a column, just keep time

Question

I am using pandas dataframe. there is a specific column has time information.

the raw data likes this:

5:15am
5:28am
6:15am

so I need to convert the raw data into datetime format:

format = '%I:%M%p'
dataset['TimeStamp'] = pd.to_datetime(dataset['TimeStamp'],format)

However, I got:

2014-07-04 05:15:00
2014-07-04 05:28:00
2014-07-04 06:15:00

I don't want the year and date information, just want time. How can I remove it. Thanks.

Answer 1

The following will convert what you have to datetime.time() objects:

dataset['TimeStamp'] = pd.Series([val.time() for val in dataset['TimeStamp']])

Output

  TimeStamp
0  05:15:00
1  05:28:00
2  06:15:00
