获取盘符列表：

response = os.popen("wmic logicaldisk get Caption")
return response.read().split()[1:]

获取当前文件路径：

current_dir = os.getcwd()

遍历当前目录下子文件：

file_names = []
for item in items:item_path = os.path.join(current_dir, item)  # 构造文件或目录的绝对路径if os.path.isfile(item_path):  # 判断是否为文件file_names.append(item_path)

文件和路径判断：

os.path.isfile(path)
os.path.isdir(path)
