I'm new to stack overflow and I just started learning programming (python).
There has been a problem for the past few months that stops me from uninstalling version 3.10.7 of python.
Basically when going to the .exe python setup program (python-3.10.7-amd64) and clicking uninstall it says that the process is done without actually doing anything and without the uninstall bar filling.
I tried various things I found on the internet or in some forums but I couldn't solve the problem and the python.org support wasn't much help either.
Feel free to ask for more details in case you need it.

So I've found a few resources on the internet, but I'm running into trouble with the version numbers. Apparently there were some "major" changes to some aspects of Python between versions 3.7 and 3.10? Since the file I'm attempting to decompile back into readable code is some years old (just happened to run across it and wanted to improve on it now that I've progressed my Python knowledge somewhat).
I'm not entirely sure there's a way around this or not, but perhaps I'm doing something wrong. I attempted to use decompyle6 ... which is where I'm running into the version issue. I suppose the most obvious answer would be to go back through the archives, install the older Python version, and decompile from IT?
I am a C# developer and have decided to jump into Bitcoin programming using Python in Ubuntu, so I don't know much about python at the moment.
I downloaded some example code and at the top it says
import bitcoin
It seems I need to somehow setup pybitcointools as a bitcoin module to use with Python based on the book Mastering Bitcoin 2nd Edition.
However, I can't seem to figure out how to install pybitcointools. I know it's not installed because my first example code gives the error:
oshirowanen#oshirowanen:~/Desktop$ python3 ./key-to-address-ecc-example.py
Traceback (most recent call last):
File "./key-to-address-ecc-example.py", line 2, in <module>
import bitcoin
ImportError: No module named 'bitcoin'
What have I already tried?
sudo aptitude install python-pip
sudo pip install pybitcointools
and I get a message saying that it has installed successfully.
The package you're looking for has an empty description on PyPI and installs nothing when you install it.
If you click on the Homepage link, it's a GitHub repo containing nothing but a README file saying:
I really don't have time to maintain this library further. If you want to fork it or use it despite lack of maintenance, feel free to clone locally and revert one commit.
So, whatever this package used to provide before December 2017, it no longer does.
Options:
Just accept that the book is obsolete and therefore useless. Even if it's only a year old. (Somewhere I still have a book that's mostly about guesses about what's going to be in Java 1.1… nowadays, I don't usually buy books unless they're about ancient-enough-to-be-stable technology.)
If you really want to, you can do what that README suggests. But honestly, if you don't know enough about Git to fork the repo and revert the blanking commit, enough about pip to install from a Git repo, and enough about Python to update and maintain the code, that's not going to do you any good.
You could try searching for other forks of the library on Github, but trying to figure out if one of them is being maintained by someone who knows what they're doing just by looking over the repos is pretty much impossible if you don't know enough about what they're doing.
You could try to find some Python Bitcoin programming community mailing list, IRC channel, forum, chat site, whatever and ask people there what they're doing. Stack Overflow is definitely not the right place to ask that. The lists and channels on Python's Community site might at least be able to point you in the right direction. Or maybe the Software Recommendations Stack Exchange, but be sure to read their help first and see if it's on topic.
I have Python 3.6 and I installed Python Python(x,y)2.7.10, but it does not work.
People told me that it can work, but I read on Stack Overflow that it cant work.
Stack Overflow answer was more than 2 and a half years ago, so I wanted to check if something changed.
I installed Python(x,y)2.7.10, and I get the icon for it, but when I click it, nothing happens (nothing appears). Can you help me with this?
I'm going to make this question as succinct and to the point as possible. I have a jupyter notebook that worked perfectly yesterday. Today, my windows 10 machine demanded an update and after updating, the jupyter notebook now cannot run. I can import libraries and define functions, but when I actually go about using the libraries and functions for computations, the [*] denoting python is busy never goes away, meaning the code is stuck (or is super slow). Even after 20 minutes the first code cell is not carried out. Yesterday, this notebook would run all 40 (roughly) cells in seconds. I have no idea why this happened, where to start trouble shooting from, or who to turn to for support. Has anyone else encountered this issue?
Windows: 10 (Version: 1607, OS Build: 14393)
Python: Anaconda (Python 3.5)
Architecture: 64 bit
Jupyter Notebook File + Resorces: https://github.com/diggetybo/ICA-Attachments
Maybe the windows update meant well, but it created a lot of upheaval on my system. I had to reconfigure a lot of settings ranging from privacy to monitor display resolution. I believe some registry entries are different, although I typically don't look registry entries on a day to day basis. Some registry switcharoo is my best guess as to why Python suffered from the update.
Good news is I got it functional again by reinstalling anaconda. It was a time consuming and desperate approach to the problem. At someone's leisure, any technical explanations as to why this might have occurred could still be worth posting. I'm hoping I won't have to do this every windows update.
I'd like to exempt myself from user error, but I'm not sure whether others have this problem or not. Please share any similar experiences in the comments.
Thanks for reading.
I installed Canopy a couple of days ago. I started it up, and explored it a little -- in other words, it opened up just fine.
Today, however, it hangs on its loading screen:
After a long while of waiting (more than an hour) and still nothing happening, I became impatient and clicked on the Canopy loading screen, and got the following:
I have tried to make sure that PYTHONPATH, etc. are cleared out. I have also uninstalled and then re-installed the program. What else might I try, and what might the problem be?
Strange, sorry to hear it #user89, and thanks for the report. This could seem like a corruption of some files. Please have a look to this knowledge base article about fully uninstalling Canopy from your system and installing again:

Please comment on this article again if that didn't help.
