从两张excel表中合并数据的熊猫

Question

我正在尝试根据列值匹配两个excel表， 我开始编写这段代码：

import pandas as pd
transit = "C\\Users\\Taqwa\\Desktop\\dta_coded\\data.xlsx"
xlsx = pd.ExcelFile(transit)
df = pd.read_excel(xlsx,"201705_ch2m","zonUnsom163")

出现以下错误：

TypeError: list indices must be integers or slices, not str

Answer 1

如果您有两个具有相同列名的单独excel文件，则可以通过以下方法进行比较

import pandas as pd

df1 = pd.read_excel('file1.xlsx')
df2 = pd.read_excel('file2.xlsx')

diff = df1[df1!=df2]
print (diff)
