The above data is actually filtered from another dataframe using the below code
df = df[df['3tier1'].between(60, 65)]
I wanted to filter values between 60 and 65 using column 3tier1 and used the above code.
Now, i want a filter to pick up data only for the months May and June i.e month 5 and 6 from the date column from the above filtered data. Is there a pandas function that can do this easily. Date column contains time as well 08:00:00+08:00 , this is basically 8 am in timezone +8
>Solution :
To filter on month, you can pass the column series to pd.to_datetime then access month by dt.month then use isin method and pass list of months you are interested in i.e. 5 and 6:
df[df['3tier1'].between(60, 65) & pd.to_datetime(df['Date']).dt.month.isin([5,6])]
