如何检查csv文件行中是否有与您的变量相等的字符串

import csv

def check_csv_for_string(csv_file, variable):
    with open(csv_file, 'r') as file:
        reader = csv.reader(file)
        line_number = 0
        for row in reader:
            line_number += 1
            for field in row:
                if field == variable:
                    print(f"Found matching string '{variable}' in line {line_number}: {row}")
                    # 或者执行其他操作

# 示例用法
csv_file = 'data.csv'
variable = 'example'
check_csv_for_string(csv_file, variable)
