提问by imrek
I would like to use urllib.quote(). But python (python3) is not finding the module.
Suppose, I have this line of code:
我想用urllib.quote(). 但是 python (python3) 没有找到模块。假设，我有这行代码：
print(urllib.quote("chateu", safe=''))
How do I import urllib.quote?
如何导入 urllib.quote？
import urllibor
import urllib.quoteboth give
import urllib或者
import urllib.quote都给
AttributeError: 'module' object has no attribute 'quote'
What confuses me is that urllib.requestis accessible via import urllib.request
让我困惑的urllib.request是可以通过import urllib.request

In Python 3.x, you need to import urllib.parse.quote:
在 Python 3.x 中，您需要导入urllib.parse.quote：
>>> import urllib.parse
>>> urllib.parse.quote("chateu", safe='')
'ch%C3%A2teu'
According to Python 2.x urllibmodule documentation:
NOTE
The
urllibmodule has been split into parts and renamed in Python 3 tourllib.request,urllib.parse, andurllib.error.
笔记
该
urllib模块已经被分成部分和更名在Python 3urllib.request，urllib.parse，和urllib.error。

urllib went through some changes in Python3 and can now be imported from the parse submodule
urllib 在 Python3 中进行了一些更改，现在可以从 parse 子模块导入
>>> from urllib.parse import quote
>>> quote('"')
'%22'

If you need to handle both Python 2.x and 3.x you can catch the exception and load the alternative.
如果您需要同时处理 Python 2.x 和 3.x，您可以捕获异常并加载替代项。
try:
from urllib import quote # Python 2.X
except ImportError:
from urllib.parse import quote # Python 3+
You could also use the python compatibility wrapper sixto handle this.
您还可以使用 python 兼容性包装器6来处理此问题。
from six.moves.urllib.parse import quote

This is how I handle this, without using exceptions.
这就是我处理这个的方式，不使用异常。
import sys
if sys.version_info.major > 2: # Python 3 or later
from urllib.parse import quote
else: # Python 2
from urllib import quote
