How to troubleshoot a module import problem in a scapy script

If you try to run a Python script importing some module and you get this following issue:

NameError: name 'IP' is not defined
or
ImportError: No module named all

check your Python script name. Probably you are using some reserved name from a function.
To fix it, rename your Python script for other name, like lala.py (to be sure you are not using a reserved function name).
Don't forget delete any .pyc file that can has any conflict with any function name.

Here's an example about how to fix it:
mv new.py lala.py
rm new.pyc
python lala.py

Enjoy it!

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work.
