Python:递归统计文件夹和子文件夹中的所有文件类型和大小

import os

def count_files(folder_path):
    file_types = {}
    total_size = 0

    for root, dirs, files in os.walk(folder_path):
        for file in files:
            file_path = os.path.join(root, file)
            file_size = os.path.getsize(file_path)
            total_size += file_size

            file_extension = os.path.splitext(file)[1]
            if file_extension in file_types:
                file_types[file_extension] += 1
            else:
                file_types[file_extension] = 1

    return file_types, total_size

folder_path = '路径/到/文件夹'
file_types, total_size = count_files(folder_path)

print("文件类型统计:")
for file_extension, count in file_types.items():
    print(file_extension, ":", count)

print("总文件大小:", total_size, "字节")
