How to stop python recursion -


i made function searches files recursively , want stop recursion when first file found: 

def search_file(path):     name in os.listdir(path):         sub = os.path.join(path, name)         if os.path.isfile(sub):             return sub#and break recursion         else:             search_file(sub)
