Python 如何在openpyxl和xlrd中获得单元格值？

我有以下工作代码，用于在excel文件中搜索关键字并打印其位置：

import openpyxl as xl 
import os 
import xlrd

file_extensions = ('.xlsx', '.xlsm', '.xls') 
keyword = 'EUROBUS' 
directory = 'M:\\moje makra'

def filenames(directory): 
    for root, dirs, filenames in os.walk(directory): 
        for filename in filenames: 
            if filename.endswith(file_extensions): 
                yield os.path.join(root, filename) 

for filename in filenames(directory):
    if filename.endswith(file_extensions):
        try:
            wb = xl.load_workbook(filename)
            print('Opened ' + filename)
            for sheet in wb.worksheets: 
                rows = sheet.max_row 
                columns = sheet.max_column
                for row in range(1,rows + 1): 
                    for column in range(1,columns + 1): 
                        if keyword in str(sheet.cell(row=row, column=column).value):
                            print('FOUND IN ' + filename)
                        else:
                            print("NOT FOUND")
        except:
                print('Failed to open ' + filename)

但是，openpyxl模块不支持.xls格式，因此我需要重写脚本以使用xlrd

我尝试了以下方法：

for filename in filenames(directory):
    if filename.endswith(file_extensions):
        try:
            wb = xlrd.open_workbook(filename)
            print('Opened ' + filename)
            for sheet in wb.sheets(): 
                rows = sheet.nrows
                columns = sheet.ncols
                for row in range(1,rows + 1):
                    for column in range(1,column +1):
                        if keyword in str(sheet.cell(row, column).value):
                            print('FOUND IN ' + filename)
                        else:
                            print("NOT FOUND")
        except:
                print('Failed to open ' + filename)

但随后代码无法打开工作簿（“打开…”然后“失败…”打印每个文件）

我还尝试将

if关键字

行更改为

str（sheet.cell_value（行、列））

，但没有效果

如何修复此问题？

更改

            for row in range(1,rows + 1):
                for column in range(1,column +1):

并删除（或缩小）Mel指出的

try

块。

如果删除

try

块，您将得到实际的错误消息，这将有助于调试此功能。这就是为什么在捕获所有异常的

try

块中放入一堆代码通常不是一个好主意。

            for row in range(rows):  # rows + 1 will result in 'out of range'
                for column in range(columns):  # note 'columns'  not 'column'
