Selecting rows with a certain weekday in DataFrame in Python

user3271033

I have a DataFrame with time index like:

df.index = [2013-09-09 06:23:18, 2013-09-10 07:09:05, ..., 2014-02-02 06:04:04]

How could I choose rows in certain weekday, like Monday? Then I won't have the rows in other weekdays. Any help appreciated.

You can get the weekday by df.index.weekday, note that Monday = 0 and Sunday = 6

To select the rows on Monday, you can do

df = df[df.index.weekday==0]
