use python to read the data in excel and generate the skew().

python3.3:

#this is a test case

-- coding: gbk --

print(“hello python!中文”)

#env config
import xlrd
import os
import xlwt3
import numpy

import pandas as pd

#from pandas import Series,DataFrame

#import pandas

data = xlrd.open_workbook(“E:\data.xlsx”)
table = data.sheets()[0] #this need to be verify more

#print (“check”)
print (table.nrows)
print (table.name)
print (“############################”)

#total line num
line_num=table.nrows

cell_sectionA=table.cell(1,0).value
cell_sectionB=table.cell(1,1).value

#print (cell_sectionA)

#print (cell_sectionB)

start_value=cell_sectionA

#we need to recode the start value ,but not the end.
sectionB_each_time_start=0

#sectionB_each_time_end=i is ok.

for i in range(1,line_num):
if start_value != table.cell(i,0).value:
cacu_num=i-sectionB_each_time_start;

#print (cacu_num)
#print ("********************************")
data={}
for j in range(0,(cacu_num-1)):
    data[j]= table.cell((sectionB_each_time_start+j+1),1).value
    #print (data[j])

df = pd.Series(data)
#print("skew\t")
#print("skew: %d  %f" %(table.cell(sectionB_each_time_start+1,0).value,df.skew()))
print("%d"%table.cell(sectionB_each_time_start+1,0).value)
#print("%f" %df.skew())

#after caculate ,update the variable.
sectionB_each_time_start=i-1
start_value=table.cell(i,0).value

#file=xlwt3.Workbook()

#table_for_wt=file.add_sheet(“test1”);

#table_for_wt.write(0,0,cell_b)

#table_for_wt.write(1,1,cell_b)

#file.save(‘E:\wtest.xls’)
