python 中的 Openpyxl 进行循环以将许多 excel 文件中的特定行合并为一个

Question

我正在尝试制作一个 python 代码，该代码从 excel 表中取出特定行并将其复制到一个表中。 我想对很多文件（大约 1000 个文件）执行此操作。 因此，我希望每个 excel 文档中的特定行放入目标 excel 文件中的新行中。 我如何修改我的代码来做到这一点？

这是我现在所拥有的：

filename =str('c:\\user\\script\\results\\viktor\\ESS_result_DetectorE503B35_Sewage.xlsx')
wb1 = xl.load_workbook(filename) 
ws1 = wb1.worksheets[0] 
 

filename1 ="c:\\user\\script\\results\\viktor\\ESS.xlsx"
wb2 = xl.load_workbook(filename1) 
ws2 = wb2.active

mr = 2
mc = ws1.max_column

for i in filename:
   for j in range (1, mc + 1): 

       c = ws1.cell(row = 3, column = j) 

       ws2.cell(row = 3, column = j).value = c.value 
 

wb2.save(str(filename1))

Answer 1

在你的情况下，你不应该循环filename字符串，而是filenames名列表。

filenames = [ur filenames here]
source_xl_filename = r'xxxxxx'
source_wb = xl.load_workbook(source_xl_filename) 
ws1 = source_wb.worksheets[0]

def batch_save_xl(filename):
    wb2 = xl.load_workbook(filename) 
    ws2 = wb2.active
    mr = 2
    mc = ws1.max_column
    for i in filename:
        for j in range (1, mc + 1): 
            c = ws1.cell(row = 3, column = j) 
            ws2.cell(row = 3, column = j).value = c.value 
    wb2.save(str(filename1))

for filename in filenames:
    batch_save_xl(filename)
