Python数据分析-pandas-修改行标签和列标签

修改行标签和列标签

使用set_index()函数修改行标签

将“订单编号”列作为行标签

import pandas as pd
a = pd.read_excel('test.xlsx',sheet_name=0)
print(a)
print('--------------')
print(a.set_index('姓名'))

使用rename()函数重命名行标签和列标签

import pandas as pd
a = pd.read_excel('test.xlsx',sheet_name=0)
print(a)
print('--------------')
a = a.rename(columns={'姓名':'A','班级':'B','专业':'C','学费':'D'},index={0:'a',1:'b',2:'c',3:'d'})
print(a)

通过为DataFrame的columns属性和index属性重新赋值来分别修改列标签和行标签

import pandas as pd
a = pd.read_excel('test.xlsx',sheet_name=0)
print(a)
print('--------------')
a.columns = ['A','B','C','D']
a.index = ['a','b','c','d']
print(a)
