使用 Python 比较 2 个 excel 文件

2022-01-25 00:00:00 python pandas excel xlrd compare

问题描述

我有两个 xlsx 文件如下:

I have two xlsx files as follows:

value1   value2   value3
0.456   3.456    0.4325436
6.24654 0.235435 6.376546
4.26545 4.264543 7.2564523

和

value1   value2  value3
0.456   3.456    0.4325436
6.24654 0.23546  6.376546
4.26545 4.264543 7.2564523

我需要比较所有单元格，如果一个单元格来自 file1 != 一个单元格来自 file2 print 那.

I need to compare all cells, and if a cell from file1 != a cell from file2 print that.

import xlrd
rb = xlrd.open_workbook('file1.xlsx')
rb1 = xlrd.open_workbook('file2.xlsx')
sheet = rb.sheet_by_index(0)
for rownum in range(sheet.nrows):
    row = sheet.row_values(rownum)
    for c_el in row:
        print c_el

如何添加 file1 和 file2 的比较单元格?

How can I add the comparison cell of file1 and file2 ?

解决方案

以下方法应该可以帮助您入门:

The following approach should get you started:

from itertools import izip_longest
import xlrd

rb1 = xlrd.open_workbook('file1.xlsx')
rb2 = xlrd.open_workbook('file2.xlsx')

sheet1 = rb1.sheet_by_index(0)
sheet2 = rb2.sheet_by_index(0)

for rownum in range(max(sheet1.nrows, sheet2.nrows)):
    if rownum < sheet1.nrows:
        row_rb1 = sheet1.row_values(rownum)
        row_rb2 = sheet2.row_values(rownum)

        for colnum, (c1, c2) in enumerate(izip_longest(row_rb1, row_rb2)):
            if c1 != c2:
                print "Row {} Col {} - {} != {}".format(rownum+1, colnum+1, c1, c2)
    else:
        print "Row {} missing".format(rownum+1)

这将显示两个文件之间不同的任何单元格.对于您给定的两个文件，这将显示:

This will display any cells which are different between the two files. For your given two files, this will display:

Row 3 Col 2 - 0.235435 != 0.23546

如果您更喜欢单元格名称，请使用 xlrd.formular.colname():

If you prefer cell names, then use xlrd.formular.colname():

print "Cell {}{}  {} != {}".format(rownum+1, xlrd.formula.colname(colnum), c1, c2)

给你:

Cell 3B  0.235435 != 0.23546
