使用 xlrd 读取 excel 表并在您搜索的字符串下方找到一个单元格值

Question

我是新手，如果我问错了，请原谅我的无知。我需要搜索工作簿以找到一个字符串，然后我需要从该字符串正下方的单元格中获取我的单元格值。当我找到该值时，我想获取它并更改 .xls 的文件名以保留文件名的前三个字母并将找到的值附加到它上面。它可以在工作表中的任何位置，没有标题，它更像是一个表格。任何帮助表示赞赏，我似乎无法找到答案。我在下面尝试查找我搜索的字符串的单元格值。我只是无法提取下面单元格中的数据。我有数千个这样的文件要查看，还有 2 个可能的字符串，虽然我的 python 代码还没有走那么远：

import os
from xlrd import open_workbook
path = "a_path"

for filename in os.listdir(path):


    book = open_workbook("some_workbook")


for sheet in book.sheets():
for rowidx in range(sheet.nrows):
    row = sheet.row(rowidx)
    for colidx, cell in enumerate(row):

        if cell.value == "String" :
                 print (sheet.name)
                 print (colidx)
                 print (rowidx)
                 print (cell.value)

新代码。我走得更远了，但现在我已经到了下一行，我找不到限制列的方法。

import os
import re
import xlrd
def rename_excel_files():
path = filename

for filename in os.listdir(path):   
    try:    
        book = xlrd.open_workbook(path + filename)
    except:
        pass
    try:
        sheet = book.sheet_by_index(0)
        for rowidx in range(sheet.nrows):
            row = sheet.row(rowidx)
            for colidx, cell in enumerate(row):
                m = re.search(r' string ', str(cell.value))
                if m: 
                    nextrow = sheet.row(rowidx + 1)
                    for i, cell2 in enumerate(nextrow):
                        newfileERnbr = (str(cell2.value).split('.')[0])
                        print (filename + newfileERnbr)
    except:
        pass                   
rename_excel_files()

这是对我有用的代码。它并不完美，但效果非常好。希望它可以在将来对其他人有所帮助。谢谢。

代码：

import os
import re
import xlrd
def rename_excel_files():
    my_list = [list] # list is your list of locations
    for path in my_list:
        for filename in os.listdir(path):   
            try:    
                book = xlrd.open_workbook(path + filename)
            except:
                pass
            try:
                sheet = book.sheet_by_index(0) #sheet number 0 based
                for rowidx in range(0,50): #row range
                    row = sheet.row(rowidx)
                    for colidx, cell in enumerate(row):
                        m = re.search(research string, str(cell.value)) #research string is you regex that you are looking for, re paramaters will change for need below
                        q = re.search(research string, str(cell.value)) #research string is you regex that you are looking for
                        if m:

                            p = (str(celllocation).split('.')[0])
                            n = re.search('\d+', p)

                        elif q:

                            else:

                sheet.unload () #speeds the whole thing up because you are closing the sheet and moving on to the next one
            except:
