Series创建方法：
#创建series
import pandas as pd
obj_list=[1,2,3,4]
obj_tuple=(4,5,6,7)
obj_dict={'a':[1,2],'b':[2,3],'c':[3,4],'d':[4,5]}
obj_series_list=pd.Series(obj_list)#通过列表创建series
obj_series_tuple=pd.Series(obj_tuple,index=list('abcd'))#通过元组创建series
obj_series_dict=pd.Series(obj_dict)#通过字典创建series
#定义属性
obj_series_list.index.name='zimu'
obj_series_list.name='data'
print "#通过列表创建series"
print obj_series_list
print "#通过元组创建series"
print obj_series_tuple
print "#通过字典创建series"
print obj_series_dict
#显示series类型及属性
print type(obj_series_list),obj_series_list.dtype
print obj_series_list.index,obj_series_list.index.name
print obj_series_list.values,obj_series_list.name结果：
#通过列表创建series

#创建dataframe
import pandas as pd
import numpy as np
obj_dict={'a':[1,2],'b':[2,3],'c':[3,4],'d':[4,5]}
obj_array=np.array([[1,2,3,4],[3,4,5,6]])
obj_series_1=pd.Series([11,12,13,14])
obj_series_2=pd.Series([21,22,23,24])
obj_dataframe_dict=pd.DataFrame(obj_dict)#通过字典创建dataframe
obj_dataframe_array=pd.DataFrame(obj_array,index=['one','two'])#通过矩阵创建dataframe
obj_dataframe_series=pd.DataFrame([obj_series_1,obj_series_2])#通过series创建dataframe
obj_dataframe_dataframe=pd.DataFrame(obj_dataframe_series,index=[0,1,'one'],columns=[0,1,2,'a'])#通过其他dataframe创建dataframe
print "#通过字典创建dataframe"
print obj_dataframe_dict
print "#通过矩阵创建dataframe"

print "#通过其他dataframe创建dataframe"
print obj_dataframe_dataframe

print obj_dataframe_dataframe.dtypes
print obj_dataframe_dataframe.values
print obj_dataframe_dataframe.columns
print obj_dataframe_dataframe.index结果：
