如下所示：

import matplotlib.pyplot as plt 
import tkinter 
import numpy as np 
import pandas as pd 
from pandas import series,dataframe 
data = {‘a':[1,2,3], 
‘c':[4,5,6], 
‘b':[7,8,9] 
} 
frame = dataframe(data,index=[‘one','two','three']) 
print(frame) 
print(frame.iloc[2]) 
print(frame.loc[‘three']) 
print(frame.b)
