Python dataframe修改列的顺序

首先创建一个dataframe，如下：

import pandas as pd
a=["1001","1002","1003"]
b=["xiaoming","xiaohong","xiaohua"]
c=["77","88","99"]
d=["87","82","91"]
dataframe = pd.DataFrame({'number':a,'name':b,'Python':c,'Math':d})

结果显示为：

	Math	Python	name	number
0	87	77	xiaoming	1001
1	82	88	xiaohong	1002
2	91	99	xiaohua	1003

现在调整列的顺序：

order = ['number','name','Python','Math']
dataframe = dataframe[order]

结果显示为：

	number	name	Python	Math
0	1001	xiaoming	77	87
1	1002	xiaohong	88	82
2	1003	xiaohua	99	91
