installing urllib in Python 3.6 fails - confusion with Python 2.7


Question

hello dear Experts,


installing urllib in Python3.7 - here i encountered issues.  I would like to import urllib to use the function 'request'.


However, I encountered an error when trying to do so. I tried pip install urllib but still had the same error. I am using Python 3.7.x Really appreciate any help. i do import urllib.request using this following code:

 

import urllib.request, urllib.parse, urllib.error
fhand = urllib.request.urlopen('data.pr4e.org/romeo.txt')
counts = dict()
for line in fhand:
words = line.decode().split()
for word in words:
counts[word] = counts.get(word, 0) + 1
print(counts) 

 

but it gives me this error: ModuleNotFoundError:
No Module named 'urllib.parse'; 'urllib' is not a package

if i look at this page: https://urllib3.readthedocs.io/en/latest/

they recomend to install this way:

 

pip install urllib3
if i do so i get back this:
root@mx:/home/martin# pip install urllib3
Requirement already satisfied: urllib3 in /usr/lib/python2.7/dist-packages (1.24.1)
root@mx:/home/martin# ^C
root@mx:/home/martin# 

 

well this is funny - since it points out some path to python 2.7

Alternatively, the manpage (https://urllib3.readthedocs.io/en/latest/ ) suggests to go this way: grab the latest source code from GitHub:

 

$ git clone git://github.com/urllib3/urllib3.git
$ python setup.py install

 

this i did not try yet! But i will do so

by the way: i allways thoguth that urllib is a standard python library (built-in) so you don't have to install it.

just import it if you need to use request by:

 

 

import urllib.request

 

i will do further investigations...

update: 

 

pip3 install urllib3  

worked 

 

.... it gave back the following: 

 

Requirement already satisfied: urllib3 in /usr/lib/python3/dist-packages (1.24.1)

finally managed to setup VSCodium on the MX-Linux (Version 19.1)

 

 

Version: 1.43.2
Commit: 0ba0ca52957102ca3527cf479571617f0de6ed50
Date: 2020-03-24T21:03:16.125Z
Electron: 7.1.11
Chrome: 78.0.3904.130
Node.js: 12.8.1
V8: 7.8.279.23-electron.0
OS: Linux x64 4.19.0-6-amd64

 

 

guess that this is the actual Version!?!  . again the machine: MX-19.1 with Python 3.7.xy installed

 

Note: at the moment VSCodium is not configured towards a python-development-system. These steps have not been made. 
conclusio: on the mx-linux i now have VSCodium besides ATOM-Editor - i like ATOM it has a nice Github-Integration.

on a sidenote: on the Windows-machine (WIN-10) i have VS-Code Version: 1.43:

see on Win10 i have the following data: 

 

1 Version: 1.43.2 (user setup)
2 Commit: 0ba0ca52957102ca3527cf479571617f0de6ed50
3 Date: 2020-03-24T07:38:38.248Z
4 Electron: 7.1.11
5 Chrome: 78.0.3904.130
6 Node.js: 12.8.1
7 V8: 7.8.279.23-electron.0
8 OS: Windows_NT x64 10.0.18363

 

 

at the moment i struggle with the following message:

 

 

 NodeJS not detected on this machine, which is required for Pymakr to work. See the Pymakr readme for dependancies.


well back to the Linux-machine with MX-Linux version 19.1 and with ATOM. on a freshly installed ATOM on MX-Linux: i have to setup a lot. for some test i run the code - taken from here: https://stackoverflow.com/questions/60908216/how-to-handle-multiple-urls-in-beautifultsoup-and-convert-the-data-into-datafram

i guess that i set up the machine /ATOM badly … - any and all help greatly appreciated. - regards Zero


I recently have read an article on using Virtual Environments for Python projects.
https://towardsdatascience.com/python-virtual-environments-made-easy-fe0c603fe601

 

and this one  Comparing Python Virtual Environment tools
https://towardsdatascience.com/comparing-python-virtual-environment-tools-9a6543643a44

 

 

guess that have to take care how i setup python on my linux-machine.
