You could answer that yourself with two seconds experimentation at the 
interactive prompt.


py> os.getcwd()
'/home/steve'
py> os.curdir
'.'

For more information, you can try reading the Fine Manual:

http://docs.python.org/library/os.html#os.getcwd

http://docs.python.org/library/os.html#os.curdir


In case it isn't obvious: no, they are completely different. os.getcwd is 
a function which returns the path of the current working directory. 
os.curdir is a string which the operating system will understand to mean 
"this directory".

No.


Both refer to the current directory, but os.curdir is not an absolute
path, so you can't chdir() to it later and expect to land it the
original directory.
