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 use df[df["Courses"] == 'Spark'] to filter rows by a condition in pandas DataFrame. Not that this expression returns a new DataFrame with selected rows. You can also write the above statement with a variable.
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]
