在win中使用python
利用subprocess.call呼叫系統指令時
若指令的最後是反斜號 "\"

import subprocess

subprocess.call('dir e:\',shell=True)

會造成以下的錯誤

c:\Python27\python.exe -u "C:\Users\nkhc\Desktop\1.py"
Process started >>>
  File "C:\Users\nkhc\Desktop\1.py", line 9
    subprocess.call('dir e:\',shell=True)
                                        ^
SyntaxError: EOL while scanning string literal
<<< Process finished. (Exit code 1)
================ READY ================

解決方式

subprocess.call('dir e:\\',shell=True)
