求助，TypeError: sequence item 0: expected a bytes-like object, str found

[qq_41938732]

小白不知道该怎么改，代码大概如下
n = 0; # 切片计数器
for i in range(part_n):
for j in range(part_n):
left_bottom_part = [left_bottom[0]+i*x_item,left_bottom[1]+j*y_item]; # 切片的左下角坐标
right_top_part = [right_top[0]+i*x_item,right_top[1]+j*y_item]; # 切片的右上角坐标
for k in range(20):
url = url0 + 'query=' + query + '&page_size=20&page_num=' + str(k) + '&scope=1&bounds=' + str(left_bottom_part[1]) + ',' + str(left_bottom_part[0]) + ','+str(right_top_part[1]) + ',' + str(right_top_part[0]) + '&output=json&ak=' + ak;
data = urllib.request.urlopen(url);
hjson = json.loads(data.read());
if hjson['message'] == 'ok':
results = hjson['results'];
for m in range(len(results)): # 提取返回的结果
col.insert_one(results[m]);
n += 1;
print ('第',str(n),'个切片入库成功')

想弄一个爬取矩形区域内poi点的，错误信息如下 Traceback (most recent call last): File "<string>", line 426, in run_nodebug File "F:\1\模块1.py", line 35, in <module> data = urllib.request.urlopen(url); File "F:\1\lib\urllib\request.py", line 223, in urlopen return opener.open(url, data, timeout) File "F:\1\lib\urllib\request.py", line 526, in open response = self._open(req, data) File "F:\1\lib\urllib\request.py", line 544, in _open '_open', req) File "F:\1\lib\urllib\request.py", line 504, in _call_chain result = func(*args) File "F:\1\lib\urllib\request.py", line 1346, in http_open return self.do_open(http.client.HTTPConnection, req) File "F:\1\lib\urllib\request.py", line 1318, in do_open encode_chunked=req.has_header('Transfer-encoding')) File "F:\1\lib\http\client.py", line 1239, in request self._send_request(method, url, body, headers, encode_chunked) File "F:\1\lib\http\client.py", line 1285, in _send_request self.endheaders(body, encode_chunked=encode_chunked) File "F:\1\lib\http\client.py", line 1234, in endheaders self._send_output(message_body, encode_chunked=encode_chunked) File "F:\1\lib\http\client.py", line 1024, in _send_output msg = b"\r\n".join(self._buffer) TypeError: sequence item 0: expected a bytes-like object, str found

说错了，输出url 看看生成了什么 意思就是print 看看url

[陈年椰子]

建议 1、不要用中文做程序文件名。 也不要用中文目录名。 2、 在这个位置， 输入 url 看看生成了什么

data = urllib.request.urlopen(url);
