When I run the following script in IDLE

import os

print(os.getcwd())

I get output as

D:\testtool

but when I run from cmd prompt, I get

c:\Python33>python D:\testtool\current_dir.py

c:\Python33

How do I get same result which I got using IDLE ?

解決方案

It seems that IDLE changes its current working dir to location of the script that is executed, while when running the script using cmd doesn't do that and it leaves CWD as it is.

To change current working dir to the one containing your script you can use:

import os

os.chdir(os.path.dirname(__file__))

print(os.getcwd())

The __file__ variable is available only if you execute script from file, and it contains path to the file. More on it here: Python __file__ attribute absolute or relative?
