How to group DataFrame by a period of time?

Question

I have some data from log files and would like to group entries by a minute:

 def gen(date, count=10):
     while count > 0:
         yield date, \"event{         


        

Answer 1

pd.TimeGrouper is now depreciated. Here is v1.05 update using pd.Grouper

df['Date'] = df.index

df.groupby(['Source',pd.Grouper(key = 'Date', freq='30min')])
