it didn't help. it reads the pathway "as is" (see errors for both

could not find it because it searched in the path/way instead of in the

The form of slash ('\' vs '/') is irrelevant to Python. At least on
Windows.
folders= ['1','2','3']
for x in folders:
print x # print the current folder
filename='Folder/%s/myfile.txt' %[x]
^- brackets not needed
f=open(filename,'r')
gives: IOError: [Errno 2] No such file or directory:
"Folder/['1']/myfile.txt"
Pay attention to the error message. Do you actually have the file
"Folder\['1']\myfile.txt" on your machine? And did you really want
brackets and quotes? Is the path located relative to whereever your
python script is running from? If it's an absolute path, precede it
with a leading slash.
As far as the Python question of string substitution, "%s" % var is an
appropriate way.
Your above code should read:
folders = ['1', '2', '3']
for x in folders:
print x
filename = 'Folder/%s/myfile.txt' % x
f = open(filename, 'r')
Again, in order for that to work, you *must* have a path/file of
'Folder\1\myfile.txt' existing from the same folder that this code is
running from. This is O/S related, not Python related.
