A query related to os.chdir

[rockzzz]

Hi guys,
I have 2 variables a and b and the following code
a= /user/temp/new
b= test

I am using

os.chdir(os.path.join('a','b'))

to change my directory to test but I am getting following error
Traceback (most recent call last):
File "bfm.py", line 50, in <module>
os.chdir(os.pat h.join('a','b') )
FileNotFoundErr or: [Errno 2] No such file or directory: 'a/b'

But I have test directory in new.
Can any one explain me how to resolve this error

print os.path.join('a ','b') to see what the resultant directory is and if it does exist. Take a look at variables vs. strings, and pay attention to which use quotes and which do not, at https://en.wikibooks.org/wiki/Python...es_and_Strings

remove the quotes from i.e.

os.path.join(a, b)

putting quotes mean you are joining strings not the variables created a line before
