统计python中跨多个csv文件出现的次数

import csv
import os

def count_occurrences(csv_files, value):
    count = 0
    for file in csv_files:
        with open(file, 'r') as csvfile:
            reader = csv.reader(csvfile)
            for row in reader:
                if value in row:
                    count += 1
    return count

csv_files = []
directory = 'path/to/csv/files'  # 替换为CSV文件所在的目录路径
for filename in os.listdir(directory):
    if filename.endswith(".csv"):
        csv_files.append(os.path.join(directory, filename))

value = 'your_value'  # 替换为要统计的特定值
occurrences = count_occurrences(csv_files, value)
print(f"The value '{value}' appears {occurrences} times across multiple CSV files.")
