Openpyxl:如何检查单元格是否包含特定值后如何复制行 [英] Openpyxl: How to copy a row after checking if a cell contains specific value

问题描述

我有一个工作表，每周更新数千行，并且需要在过滤后从该工作表中转移行.我正在使用当前代码查找具有所需值的单元格，然后将整行传输到另一张工作表，但是保存文件后，出现"IndexError:列表索引超出范围"异常.

I have a worksheet that is updated every week with thousands of rows and would need to transfer rows from this worksheet after filtering. I am using the current code to find the cells which has the value I need and then transfer the entire row to another sheet but after saving the file, I get the "IndexError: list index out of range" exception.

我使用的代码如下:

import openpyxl

wb1 = openpyxl.load_workbook('file1.xlsx')
wb2 = openpyxl.load_workbook('file2.xlsx')

ws1 = wb1.active
ws2 = wb2.active

for row in ws1.iter_rows():
    for cell in row:
        if cell.value == 'TrueValue':
            n = 'A' + str(cell.row) + ':' + ('GH' + str(cell.row))
            for row2 in ws1.iter_rows(n):
                ws2.append(row2)

wb2.save("file2.xlsx")

我以前用来工作的原始代码如下，由于大文件导致MS Excel无法打开它们(超过40mb)，因此必须对其进行修改.

The original code I used that used to work is below and has to be modified because of the large files which causes MS Excel not to open them (over 40mb).

n = 'A3' + ':' + ('GH'+ str(ws1.max_row))
for row in ws1.iter_rows(n):
    ws2.append(row)

谢谢.

推荐答案

使用列表保存特定行的每一列中的项目. 然后将该列表附加到您的 ws2 .

Use a list to hold the items in each column for the particular row. Then append the list to your ws2.

...

def iter_rows(ws,n):  #produce the list of items in the particular row
        for row in ws.iter_rows(n):
            yield [cell.value for cell in row]

for row in ws1.iter_rows():
    for cell in row:
        if cell.value == 'TrueValue':
            n = 'A' + str(cell.row) + ':' + ('GH' + str(cell.row))
            list_to_append = list(iter_rows(ws1,n))
            for items in list_to_append:
                ws2.append(items)
