How to read specified columns

[Raj]

Hi,

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from scipy import stats
dataFileName='RFInput.xlsx'
sheetName='Rawdata'
sheetNamePara='paraList'
dataRaw=pd.read_excel(dataFileName,sheetname=sheetName)
datapara=pd.read_excel(dataFileName,sheetname=sheetNamePara)

noData=len(dataRaw)
import matplotlib.pylab as plt
from sklearn.cross_validation import train_test_split
from sklearn.cross_validation import cross_val_score
from sklearn.preprocessing import StandardScaler
import pandas as pd
import numpy as np
 
labels=datapara
x=dataRaw[labels]
y=dataRaw['classVariable']

labels are becoming dataFrame type, can not read data of column (specified in labels)
