a simple 'for' question

Hi fans,

I want to use a 'for' iteration to manipulate files in a set of folders, 
something like:

folders= ['1A28','1A6W','56Y7']
for x in folders:
    print x     # print the current folder
    f = open('my/path/way/x/my_file.txt', 'r')

where 'x' in the pathway should iterate over '1A28','1A6W','56Y7'.  How 
should I identify 'x' in the pathway line as the same x that is 
iterating over 'folders'?

I am getting the following error:

Traceback (most recent call last):
line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Linux\Dock_method_validation\myscripts\test_for.py", line 5, 
in <module>
    f = open('c:/Linux/Dock_method_validation/x/receptor.mol2', 'r')
IOError: [Errno 2] No such file or directory: 

I tired several variations: %x, 'x', "x", etc. all gave me similar errors.

Thanks for your help,
