如何從文件 csv 中刪除一行？

Question

我寫了一個代碼來從文件中刪除一行，由於某種原因，刪除刪除了文件中的所有內容，我無法弄清楚我的代碼有什么問題......如果有什么可以幫助我？ 謝謝！ 行 = 列表（）

members = int(rownumber)

with open('C:\\Users\\Administrator\\Desktop\\plan.csv', 'r') as readFile:

    reader = csv.reader(readFile)

    for row in reader:

        lines.append(row)

        for field in row:

            if field == members:
                lines.remove(row)

with open('C:\\Users\\Administrator\\Desktop\\plan.csv', 'w') as writeFile:

    writer = csv.writer(writeFile)

    writer.writerows(lines)

您能否澄清從文件中排除一行的條件。 我將假設您要刪除行號members

members = int(rownumber)

with open('C:\\Users\\Administrator\\Desktop\\plan.csv', 'r') as readFile:

    reader = csv.reader(readFile)

    for i, row in enumerate(reader):
        # 'i' holds to current row number
        # if it's equal to 'members', don't append it to the list
        if i != members:
            lines.append(row)


with open('C:\\Users\\Administrator\\Desktop\\plan.csv', 'w') as writeFile:

    writer = csv.writer(writeFile)

    writer.writerows(lines)
