If you have a mapping of strings to values, you should just go ahead
and store them in a dictionary.  Then the lookup becomes simple:

def foo(list_of_strings):
	mapping = {
		"bar0": "/var/log/bar0.log",
		"bar1": "/usr/local/bar/bar1.txt",
		"bar2": "/home/joe/logs/bar2.log",
	}
	for item in list_of_strings:
		filename = mapping[item]
		do_something(filename)
