Sometimes it's the line above this error you should look at. It should tell you what package is missing.
Check :
libpython3.7-dev:amd64: /usr/include/python3.7m/Python.h
virtualenv is the Python 2 tool to interact with virtual environments and won't be discussed here. I'll focus on Python 3 tools and methods only.
The Python 3 tool to manage virtual environments is venv, which —depending on your distro / version :
(myVirtualEnvironmentName)
showing the virtual environment is enabled.

This is highly context-specific and not exactly a "clean" solution, but maybe this will give you hints to find the root cause on your side... If anything, this issue,at least, led me to some best practices :
First, some general advice. It is assumed that anyone encountering issues will have failed to follow some part of this advice. Listing these items here is not intended to imply that "it's your fault and we won't help", but rather to help users to identify what went wrong, so that they can work out what to do next more easily.
PATH issues you need to be aware of here. We'll cover these later. Put simply, it's possible to follow this advice, and still hit problems, because you're not actually running the wrapper you installed as --user.

List comprehensions provide a more concise way to create lists in situations where nested loops would currently be used.
print({x: y for (x, y) in zip(inTable, outTable)})
{'K': 'M', 'E': 'G', 'O': 'Q'}
print({ord(x): y for (x, y) in zip(inTable, outTable)})

i hope you didnt translate it by hand. thats what computers are for. doing it in by hand is inefficient and that's why this text is so long. using string.maketrans() is recommended. now apply on the url.A smarter solution to build the
inTable and outTable strings :
import string inTable = string.ascii_lowercase outTable = string.ascii_lowercase[2:] + string.ascii_lowercase[:2]

Due to Python's byte objects, print's internal logic and things that are not yet clear to me (and Python3.x limitations on lxml side ?), this script outputs a "byte object string", that I'll clean (the ugliest possible way) with sed :
