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

Since the original answer is rather old and pandas introduced periods a different solution is nowadays:

df.groupby(df.index.to_period('T'))

Additionally, you can resample

df.resample('T')
