I get the following error:
I did this too to verify:
What am I doing wrong?
回答1:
Import urllib.request instead of urllib.
import urllib.request

Interestingly, I noticed some IDE-depending behavior.
Both Spyder and PyCharm use the same interpreter on my machine : in PyCharm I need to do
import urllib.request
while in Spyder,
import urllib
does fine

If this is on PyCharm, as was mine, make sure your file name isn't urllib.py.
回答4:
- In visual code , u have to write import urllib.request instead of just import urllib.
- Also, whenever errors such as module x has no attribute y occurs, it's because you have named the current file same as the package you are trying to import.
- So, the way import in python works is that it first searches the current dir, and if it finds the module/package 'x' u were looking for , it assumes that it has found the target file, and searches for 'y'. And since u haven't defined 'y', the aforementioned error occurs.
