python-获取目录内所有文件的绝对路径，获取文件大小并输出到txt文件中

代码如下：

import os

dirpath = 'D:\\'   

t = []
for root,dirs,files in os.walk(dirpath):
    for file in files:
        temp = os.path.join(root,file).replace('\\','\\\\')
        if os.path.isfile(temp):
            t.append(temp)

if (os.path.exists("filesize.txt")):
    os.remove("filesize.txt")

f=open("filesize.txt","a",encoding='utf-8')
i = 0
while i < len(t):
     f.writelines('size:'+ str(os.path.getsize(t[i])) + "\n" + t[i]+ "\n")
     i = i +1
f.close()
