I'm having trouble with something that seems like it should be simple. I need to copy a file, say "abc-1.tif" to another directory, but if it's in there already, I need to transfer it named "abc-2.tif" but I'm going about it all wrong.
Here's what doesn't work: (I'll add the copy stuff from shutil after figuring out the basic string manipulation.) import os source = r"C:\Source" target = r"P:\Target" files = os.listdir(source) for f in files: if os.path.isfile(target + "\\" + f): # if it already exists print f + " exists" s = f # i'd like a copy to alter s = s.replace("-1", "-2") print "Altered it to be " + s print source + "\\" + s, target + "\\" + s else: print f + " IS NOT THERE YET" print source + "\\" + f, target + "\\" + f # use the original -- http://mail.python.org/mailman/listinfo/python-list
