How to Group by 5-Minute Intervals in Pandas

---

You can use the following basic syntax to group rows by 5-minute intervals in a pandas DataFrame:

df.resample('5min').sum()

This particular formula assumes that the index of your DataFrame contains datetime values and it calculates the sum of every column in the DataFrame, grouped by 5-minute intervals.

The following example shows how to use this syntax in practice.

Suppose we have the following pandas DataFrame that shows the sales made by some company on various dates and times:

import pandas as pd

#create DataFrame
df = pd.DataFrame({'date': pd.date_range(start='1/1/2020', freq='min', periods=12),
                   'sales': [6, 8, 9, 11, 13, 8, 8, 15, 22, 9, 8, 4],
                   'returns': [0, 3, 2, 2, 1, 3, 2, 4, 1, 5, 3, 2]})

#set 'date' column as index
df = df.set_index('date')

#view DataFrame
print(df)

                     sales  returns
date                               
2020-01-01 00:00:00      6        0
2020-01-01 00:01:00      8        3
2020-01-01 00:02:00      9        2
2020-01-01 00:03:00     11        2
2020-01-01 00:04:00     13        1
2020-01-01 00:05:00      8        3
2020-01-01 00:06:00      8        2
2020-01-01 00:07:00     15        4
2020-01-01 00:08:00     22        1
2020-01-01 00:09:00      9        5
2020-01-01 00:10:00      8        3
2020-01-01 00:11:00      4        2

We can use the following syntax to calculate the sum of sales grouped by 5-minute intervals:

#calculate sum of sales and returns grouped by 5-minute intervals
df.resample('5min').sum()

                     sales returns
date		
2020-01-01 00:00:00	47	 8
2020-01-01 00:05:00	62	15
2020-01-01 00:10:00	12 	 5

Here’s how to interpret the output:

• Total sales during minutes 0-4 was 47 and total returns was 8.
• Total sales during minutes 5-9 was 62 and total returns was 15.
• Total sales during minutes 10-14 was 1 2and total returns was 5.

We can use similar syntax to calculate the max of the sales values and returns values, grouped by 5-minute intervals :

#calculate max of sales and max of returns grouped by 5-minute intervals
df.resample('5min').max()

	             sales  returns
date		
2020-01-01 00:00:00	13	  3
2020-01-01 00:05:00	22	  5
2020-01-01 00:10:00	8	  3

We can use similar syntax to calculate any value we’d like grouped by 5-minute intervals.
