我有一个我定义的类,该类目前有2个参数,self和savepath。这个类的方法有2个参数,self。在该方法中,我调用一个函数,它再次接受2个参数,local_hash和filename,但是,在调用此方法时,我得到下面描述的错误。我认为它与自我论证有关,但我无法弄清楚在哪里或为什么。对于记录,put_nowait()是默认模块的方法。我不认为我需要发布我正在使用的所有相关默认模块的代码。
def cache_files(self, path):
self.folder_path = path
self.md5_queue = Queue.Queue()
accepted_file_types = ['.jpg', '.png', '.gif']
self.hash_directory = os.walk(self.folder_path, topdown=True)
if self.folder_path != None:
for root, subfolders, images in self.hash_directory:
for filename in images:
try:
if filename[-4:] in accepted_file_types:
self.local_hash = hash_sum(os.path.join(root, filename))
self.md5_queue.put_nowait(filename, self.local_hash)
except IOError:
continue
print 'Directory has finished caching, exiting...'
return self.md5_queue
def run(self):
# references pickle file if available
md5_path = os.path.join(os.path.dirname(__file__), 'md5.pickle')
try:
self.md5_dict = md5_unpickler(md5_path)
except IOError:
pass
if self.hash == True:
self.cache_files(self.savepath)
else:
self.build_queue()
Traceback (most recent call last):

你可能在'put_nowait'方法的参数列表中缺少'self'。我相信这样的事情:
class md5_queue:
def put_nowait(filename, local_hash):
.
.
.
将其更改为以下内容可以解决您的问题:
class md5_queue:
def put_nowait(self, filename, local_hash):
.
.
.

找到我的答案。 put_nowait()期待2个参数,put_nowait(self,(tuple,here))。不(元组,这里)。
