Pandas convert timers to multiple columns DataFrame
I have temporary data of intraday data as shown below
ts =pd.Series(np.random.randn(60),index=pd.date_range('1/1/2000',periods=60, freq='2h'))
I am hoping to convert data to a DataFrame with columns as each date and row as time in date.
I have tried these,
key = lambda x:x.date()
grouped = ts.groupby(key)
But how to convert groups to DataFrame columns with date date? or is there a better way?

import pandas as pd
import numpy as np
index = pd.date_range('1/1/2000', periods=60, freq='2h')
ts = pd.Series(np.random.randn(60), index = index)
key = lambda x: x.time()
groups = ts.groupby(key)
print pd.DataFrame({k:g for k,g in groups}).resample('D').T
