You have 3 leading underscores in __main__ so the if statement is skipped and
nothing happens.
I'd use the split method of string objects, and there is no need for a
file_found variable:
def search_file(filename, search_path):
"""Given a search path, find file
"""
for path in search_path.split(pathsep):
fullpath = join(path, filename)
if exists(fullpath):
return abspath(fullpath)
# there is an implicit return None at the end
