Issue
I received data similar to this format
Time Humidity Condition
2014-09-01 00:00:00 84 Cloudy
2014-09-01 01:00:00 94 Rainy
I tried to use df.resample('5T')
but it seems the data cannot be replicated for the same hour and df.resample('5T')
need the function like mean() but I do not need it.
But the problem is... I don't want to use 'mean', because it does not keep "Humidity" and "Condition" as original. I just want the data be
Time Humidity Condition
2014-09-01 00:00:00 84 Cloudy
2014-09-01 00:05:00 84 Cloudy
2014-09-01 00:10:00 84 Cloudy

2014-09-01 00:55:00 84 Cloudy
2014-09-01 01:00:00 94 Rainy
2014-09-01 01:05:00 94 Rainy
2014-09-01 01:10:00 94 Rainy

Wonder is there is a way out, could ask if there is any solution to this issue? Many thanks!
Solution
Example
data = {'Time': {0: '2014-09-01 00:00:00', 1: '2014-09-01 01:00:00'},
'Humidity': {0: 84, 1: 94},
'Condition': {0: 'Cloudy', 1: 'Rainy'}}
df = pd.DataFrame(data)
df
Time Humidity Condition
0 2014-09-01 00:00:00 84 Cloudy
1 2014-09-01 01:00:00 94 Rainy
Code
i make code for 20T
instead 5T
, becuz 5T
is too short.
(df.set_axis(pd.to_datetime(df['Time']))
.reindex(pd.date_range(df['Time'][0], freq='20T', periods=6))
.assign(Time=lambda x: x.index)
.reset_index(drop=True).ffill())
result:
Time Humidity Condition
0 2014-09-01 00:00:00 84.0 Cloudy
1 2014-09-01 00:20:00 84.0 Cloudy
2 2014-09-01 00:40:00 84.0 Cloudy
3 2014-09-01 01:00:00 94.0 Rainy
4 2014-09-01 01:20:00 94.0 Rainy
5 2014-09-01 01:40:00 94.0 Rainy
