without specifying what you expect to see & what you are actually seeing 
it is difficult for anyone to understand your problem let alon provide 
the solution. 

that said it looks like you need to develop your debugging skills so that 
you can hep yourself, try adding print statements at critical points in 
your program to check that your variables contain what you think they 
should ate each stage, this will help you pinpoint the point in your code 
you need to investigate.

example:

cwd=os.getcwd()
print (cwd) // is cwd what you expect? if not why not
path = os.path.join(cwd,'myfile')
print (path) // is path what you expect  ?if not why not?

when you identify the part that is wrong post back with what you expect & 
what you get.
