python按特定值删除某一行csv

可以使用Python的csv模块来处理csv文件，具体步骤如下：

1.打开csv文件

import csv

with open('file.csv', 'r') as csvfile:
    reader = csv.reader(csvfile)

2.遍历csv文件中的每一行，判断是否需要删除

rows = []
for row in reader:
    if row[0] != '特定值':
        rows.append(row)

3.将更新后的行写入一个新的csv文件中

with open('new_file.csv', 'w', newline='') as newfile:
    writer = csv.writer(newfile)
    writer.writerows(rows)

完整代码如下：

import csv

with open('file.csv', 'r') as csvfile:
    reader = csv.reader(csvfile)
    rows = []
    for row in reader:
        if row[0] != '特定值':
            rows.append(row)

with open('new_file.csv', 'w', newline='') as newfile:
    writer = csv.writer(newfile)
    writer.writerows(rows)

其中，'file.csv' 是要处理的csv文件名，'特定值' 是要删除的行对应列的值，'new_file.csv' 是处理后生成的新文件名。
