I don't see urllib.request module in python3. Throws following error. Am I missing something? I want to access urllib.request.urlopen

As per below link urllib should have request module.
https://docs.python.org/3.4/library/urllib.request.html#urllib.request.Request.method.
In Python 3 you need to import urllib.request instead of urllib'
Like this:
>>> import urllib.request
>>> urllib.request.Request
<class 'urllib.request.Request'>

I installed airflow within one of my Anaconda envs named engdados. When I execute the command airflow initdb I'm getting the following error: airflow initdb: cannot import name 'Pendulum' from 'pendulum'. The full trace back is shown below:

from pendulum import Pendulum
ImportError: cannot import name 'Pendulum' from 'pendulum' (/home/guilherme/anaconda3/envs/engdados/lib/python3.8/site-packages/pendulum/__init__.py)
The problem is: the pendulum is installed! When I execute the conda list command I can see the Pendulum there as follows:
Name Version Build Channel
pendulum 2.1.2 pypi_0 pypi
What I've checked so far:
Is the engdados environment activated? Yes
Is the Pendulum installed on Anaconda environment? Yes
The version of Pendulum the Anaconda shows is different of the one showed in conda list (1.4.4). Why?
I have no idea what is going on. Thanks in advance.
In pendulum version 2, the class pendulum.Pendulum is replaced with pendulum.DateTime.
Your version of airflow is expecting pendulum 1.x but your environment has 2.x.
You may be able to fix this by making a new env and installing airflow 2.0 (which uses pendulum 2.x). If you must use airflow < 2.0, you will need to pin pendulum to < 2.0 (e.g. using pip constraints).
Also if you using Pendulum in your code, for example in custom Operators you can add
try:
from pendulum import DateTime as Pendulum
except ImportError:
from pendulum import Pendulum
