Python 写一个打印文件夹目录，并写入到文件中

import os

# 需要打印的文件目录路经
path = "D:/test/"

# 创建a.txt 并追加文本
def writeA(txt):
	with open('a.txt', mode='a') as filename:
	    filename.write(txt)
	    filename.write('\n') # 换行
	    
# 循环遍历文件夹中的子文件和目录
def loadFile():	 
	for folderName ,subfolders ,filenames in os.walk(path):	
		writeA(folderName)
		for subfolder in subfolders:
			writeA(subfolder) 
		for filename in filenames:
			writeA(filename)

		writeA(' ')

	 


if __name__ == "__main__":
	loadFile()
