I found a way to create daily averages of many variables, for example of a
database that has the following structure:
Fecha,Time, DirViento, MagViento, Temperatura, Humedad, PreciAcu.
Each column is daily data every 15 minutes. I share the code, which, with the
help of your comments I have adapted to my project. The code calculates the
average of the columns Temperatura and Humedad as well as the sum of column
PreciAcu. The code is as follows:
import numpy as np
import pandas as pd
data = pd.read_csv('tancoyol.csv')
index5=data.set_index(['Fecha','Hora'],inplace=True)
grouped = index5.groupby(level=0)
stat_cea =
grouped.agg({'Temperatura':np.mean,'Humedad':np.mean,'PreciAcu':np.sum})
print 'Done............'
Now I have one more question, I need to convert to radians the DirViento
column, how I can do this and how can add this new column to my data file?
In summary,i need to obtain 3 columns from the DirViento column agregate to
datafile.
DirViento
1/07/2011 00:00:00
1/07/2011 00:15:00
1/07/2011 00:30:00
1/07/2011 00:45:00
2/07/2011 00:00:00
2/07/2011 00:15:00
2/07/2011 00:30:00
2/07/2011 00:45:00
.
.
.
Specifically:
First I need to convert the values of DirViento column to Radians (This should
be a new column called Rad) Second I need to get the sine of Rad column (This
should be a new column called Sin) Third I need to get the cosine of Rad column
(This should be a new column called Cos).
How I can achieve this?
