QUESTION
I have two JSON files of same format, forexample
1st JSON File
...ANSWER
Answered 2020-Nov-05 at 13:24Since you are looping through json file it will search inside of "data" so you can't use $v['data']
Also since edges
is also array that have same values and you want to search inside of it you must make loop on that also
Here is example

QUESTION
Ubuntu 18.04 used by me (a noob) who has pip installed packages all over the place until I learned the benefit of virtual environments. My .bash rc file contains:
...ANSWER
Answered 2019-Apr-01 at 18:33The reason why pip installed to your python3.6 library is because it is a default library for pip installation on your machine.
pip --version
will return the location where pip is going to install your packages.
If you want to install the package for python2.7, run pip2 install plumbum --user
I would also recommend to run pip2 --version
beforehand.
EDIT:
I suggest you also look at this answer, to make sure you understand the differences between pip
, pip3
, python
, python2
, python3

QUESTION
I've googled this quite a bit and am unable to find helpful insight. Basically, I need to take the user input from my argparse arguments from a python script (as shown below) and plug those values into a json file (packerfile.json) located in the same working directory. I have been experimenting with subprocess
, invoke
and plumbum
libraries without being able to "find the shoe that fits".
From the following code, I have removed all except for the arguments as to clean up:

Answered 2018-Dec-29 at 21:51You might use the __dict__
attribute from the SimpleNamespace
that is returned by the ArgumentParser
. Like so:
QUESTION
What are pros and cons of Fabric and Plumbum python libraries for local/remote command execution? What are use cases when one library should be used and other is not? What are the differences attention should be drawn to?
...ANSWER
Answered 2018-Jul-18 at 08:39They're pretty much the same thing. The biggest win for fabric over plumbum is the ability to connect to multiple hosts in parallel, which is more or less indispensible when you're working with a non-trivial setup. fabric also offers a couple of contrib helpers that let you upload jinja templates, upload files, and transfer files back to the local system. I personally find the fabric api to be far more intuitive for working with remote servers.
YMMV, of course, but both are geared towards being very close to shell commands. That said, my team and I are focused on ansible for most configuration / deploy flows. Fabric does offer some power over ansible at the expense of having to roll your own idempotence.
QUESTION
Is there a good built-in way to connect through a 'jump host' with Plumbum.
I've thought about subclassing ParamikoMachine
to provide my own SSHClient object.
Any other ideas?

Answered 2018-Jun-28 at 18:27Try using ssh_opts
of SshMachine

QUESTION
I'm porting a project to Python3 and I'm running into a unexpected error on Windows:
Basically on Python 3.6 on Windows, each time a process is being created with subprocess, I have this exception:
...ANSWER
Answered 2017-Dec-06 at 07:41After a bit of pause, I quickly found the reason behind this.
It was because of the GitPython
usage in the project which didn't call git.Repo.close()
or used git.Repo
as a context manager.
There is a warning about this on GitPython
's readme.
It was helpful to add logging in subprocess
's _internal_poll
method to know which process (args
) is the culprit. For GitPython
it was git cat-file

Install plumbum
You can use plumbum like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
