我是在windows上的,把e盘的一个文件夹里的文件备份到同在e盘的另一个文件,但是却出现错误,不知道是怎么回事儿,现在把代码和错误帖在下
面。
code:
import os
import time
source=[r'e:\backup']
target_dir=[r'e:\satan']
today=target_dir+time.strftime('%Y%m%d')
now=time.strftime('%H%M%S')
if not os.paht.exists(today):
os.mkdir(today)
print 'successfully created directory',today
target=today+os.sep+now+'.zip'
zip_command="zip -qr '%s' %s" %(target,' '.join(source))
if os.system(zip_command)==0:
print 'successful backup to',target
else:
print 'back failed'

error:
Traceback (most recent call last):
File "C:/Users/fenghelong/Desktop/python操作/backup_ver2.py", line 5,
in <module>
today=target_dir+time.strftime('%Y%m%d')
TypeError: can only concatenate list (not "str") to list

这个是 list 呗

time.strftime 是个字符串呗?
两个东西能用加号串接么?
