How to Solve Python AttributeError: ‘module’ object has no attribute ‘xxx’

Python script error attributeerror: ‘module’ object has no attribute ‘xxx’ solution

when you encounter a few problems, you should pay attention to the same problem when you don’t ask for a solution

1. When naming py script, it should not be the same as the reserved word and module name of Python
(it is not easy to notice when naming files)
2 Delete the. PyC file of the library (because the. PyC file will be generated every time the PY script runs; if the. PyC file has been generated, if the code is not updated, the runtime will still go PyC, so you need to delete the. PyC file), rerun the code, or find an environment where you can run the code and copy and replace the. PyC file of the current machine Import questions </ font> </ font>

Attributeerror: object has no attribute

Error report: in the front-end test, the interface sends a put request, the error report occurs on the interface, the request cannot respond, and the server status code is 500.

Error analysis: semantically, “the object does not have a XXX attribute.”.

Look up most of the information, most of the problems with Python. The front end of this project uses react, and the back end uses the djongo framework of Python.

The main reason for asking the back-end colleagues is that the data type of the parameters passed by the front-end is incorrect. The back end needs a string “true”, but the front end passes a Boolean “true”, which causes the above problem.

In case of such a problem, the error code returned by the server is 500. For such a problem, usually ask the back-end colleagues to check the log for common analysis.

Solving attributeerror: module ‘urllib’ has no attribute ‘request’

Using urllib in Python 3 is an error like this:

Traceback (most recent call last):
  File "*.py", line 34, in <module>
    html_page = get(URL, req_header)
  File "*.py", line 18, in get_HTML
    request = urllib.request.Request(url, headers=req_header)
AttributeError: module 'urllib' has no attribute 'request'

An error code

import urllib
request = urllib.request.Request(url, headers=req_header)
html = urllib.request.urlopen(request).read()
print (html)

Error reason:
in the Python AttributeError errors there are two kinds of main reason:
1.
2. File with same name exists in project directory

> port urllib.request <>ode> >

import urllib
import urllib.request
request = urllib.request.Request(url, headers=req_header)
html = urllib.request.urlopen(request).read()
print (html)
