Sorry for that, I think I'm really mistaking in something simple because I could not even find someone with a similar problem after some googling.
I firstly got the error when I tried to use fireplace's :Connect.
Apparently it is installed (but not corretly, because :help fireplace doesn't work) but it returns Python interface not working.
Again, sorry for this newbie question.
Read the documentation:
The only external dependency is that you have either a Vim with Python support compiled in, or python in your path.
There you have it. Make sure you have Python in your path (typing python on the command-line brings up a Python interpreter), or install a Vim with Python support (in Vim, :echo has('python') returns 1). You can find many many questions and answers with the details for both of these on Stack Overflow.

so I'm pretty new to both swift and stack, but I have a problem with implimenting Pythonkit. But basically to provide a short summary, the kit basically allows you to be able to utilize python inside of swift (using certain swift functions in order to save variables, do functions, however, can execute the code of a .py file).
In the process of doing this however this error pops up
Fatal error: Python library not found. Set the PYTHON_LIBRARY environment variable with the path to a Python library.: file /Users/****/Library/Developer/Xcode/DerivedData/Y******L-
So I tried updating my Python software to 3.0 and above (I'm not quite sure, I think it was 3.7), however when I run python it shows it is at version 2.7. This kind of confused me a bit, however it was until the error did I notice something was wrong. Why does it show that error? What does it mean?
(I did find a similar post with a similar error in stack overflow, however I don't have enough reputation to comment as well as I don't think the answer was addressed to what I wanted so I'm just going to continue writing here)
The swift code itself has updated (xcode11) and following the steps a lot of the functions have changed within Xcode, what is it that I did wrong that caused the error? Following the link it seems I have to utilize pyto? Checking that link the functions of pyto are different than the ones pf PythonKit. In PythonKit you can utilize python within your swift code, while pyto seems to be a python integration for iOS?
Any advice? And please ask if anything needs clarification, or if there's a different solution please tell me. Thanks,Vince
I'm following this tutorial to get my Python application (which use DBus) working on windows.
I'am at the step Build DBus (using MiNGW and therefore gcc).
So, here we are at my problem: There is an error while compiling:
As you can see, it's just a syntax problem...
I've tried to fix it directly into the concerned file, but lt-dbus-monitor.c seems to be a generated one and i've not been able to find which generates it (The makefile is so obfuscated).
May someone have a solution to this ?
All right, i feel a bit stupid...
For those who will be interested: I've just replaced spaces from "scratch MiNGW DBus" with underscores...
I guess it does not like spaces in folder name, obviously.

I'm rather new to Python, though hope to use it for both programming and scripting. I've written basic scripts, and did some digging for compiling. I'm currently using py2exe (With a different setup.py script someone else made) so that it becomes ONE simple .exe, without dependencies (python DLL, etc.)
You're probably wondering what my problem is. Well, I decided to check the security of the executable, and view it in Resource Hacker. I was able to view all the parts of the script I DIDN'T want people to be able to find out. (Ex: Password inputs).
Can anyone give me a simple, working method, for converting PYTHON code to a STANDALONE executable that CANNOT allow viewing of the original python script via something like Resource Hacker?
I am not thoroughly knowledgeable in the field.. I'm also not developing commercially (Yet), I just want to make things for myself, that I may also make for other people.. Though I might freelance for random people online doing things. Anyways point being, if I had a script where it prompted you for a password, and if you got it correct it continued, else, it cancelled and exited.... then once I make it a .exe, opening in Resource Hacker, and viewing the "Python Script", I scroll to the bottom, and bam! It shows the passwords. Now when I say I'm new, I mean, really REALLY new. Anyways, if you don't mind explaining, "Encryptions", "Hash's", etc... I would prefer to be enlightened towards these subjects.'
Your help is appreciated.
Here are the simple steps (with freeze)-
You will need to use a python installation which has all its modules installed as shared libraries
freeze.py usually resides under <python_install>/Tools/freeze/freeze.py
e.g: Python-2.4.2/linux/Tools/freeze/freeze.py
Now to integrate freeze a very simple program, which does not have dependency on any custom python module you will just need to call freeze in this fashion:
e.g:
cat hello.py
#!/usr/bin/env python
print "Testing"
To Freeze:
a. Python-2.4.2/linux/Tools/freeze/freeze.py hello.py
b. make
you will see there is a executable hello.
file hello
hello: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), not stripped
that's it:
now invoke hello will produce:
[0:22:47]% ./hello

I am trying to incorporate an autocomplete feature in Vim. I have used the omnicompletion of Vim as well as Pydiction. But in both the cases this message pops up:
Omni completion (^O^N^P) Pattern not found
I have tried Vim's Omnicompletion with Python just doesn't work. But this is not helping. Is there a workaround?
Try Jedi! There's a Vim plugin at https://github.com/davidhalter/jedi-vim.
It works just much better than anything else for Python in Vim. It even has support for renaming, goto, etc. The best part is probably that it really tries to understand your code (decorators, generators, etc. Just look at the feature list).
As pointed out by in the comments, this answers is outdated. youcompleteme now supports python3 and jedi-vim no longer breaks the undo history.
Original answer below.
AFAIK there are three options, each with its disadvantages:
youcompleteme: unfriendly to install, but works nice if you manage to get it working. However python3 is not supported.
jedi-vim: coolest name, but breaks your undo history.
python-mode does a lot more the autocomplete: folding, syntax checking, highlighting. Personally I prefer scripts that do 1 thing well, as they are easier to manage (and replace). Differently from the two other options, it uses rope instead of jedi for autocompletion.
Python 3 and undo history (gundo!) are a must for me, so options 1 and 2 are out.
This can be a good option if you want python completion as well as other languages. https://github.com/Valloric/YouCompleteMe
The python completion is jedi based same as jedi-vim.
I tried pydiction (didn't work for me) and the normal omnicompletion (too limited). I looked into Jedi as suggested but found it too complex to set up. I found python-mode, which in the end satisfied my needs. Thanks #klen.
I found a good choice to be coc.nvim with the python language server.
It takes a bit of effort to set up. I got frustrated with jedi-vim, because it would always freeze vim for a bit when completing. coc.nvim doesn't do it because it's asyncronous, meaning that . It also gives you linting for your code. It supports many other languages and is highly configurable.
The python language server uses jedi so you get the same completion as you would get from jedi.
Use install coc.nvim package and CocInstall coc-pyright
if you are using vim-plug:
Plug 'neoclide/coc.nvim'
:PlugInstall
CocInstall coc-pyright
I ran into this on my Mac using the MacPorts vim with +python. Problem was that the MacPorts vim will only bind to python 2.5 with +python, while my extensions were installed under python 2.7. Installing the extensions using pip-2.5 solved it.
After using C# for long time I finally decided to switch to Python.
The question I am facing for the moment has to do about auto-complete.
I guess I am spoiled by C# and especially from resharper and I was expecting something similar to exist for Python.
My editor of choice is emacs and after doing some research I found autocomplete.pl, yasnippet and rope although it is not clear to me if and how they can be installed in a cygwin based system which is what I use since all the related documentation appears to be linux specific...
The version of emacs I currently use is 23.2.1 which bundles the python mode that although useful is far behind from whatever research has to offer.
My question to python users has to do about how common is autocomplete vs manual typing (using M-/ where possible) ?
I am thinking about just memorizing python build-in functions like len, append, extend etc. and revert close to a pre-autocomplete editing mode. How different such an approach is from what other pythonistas are doing?
I found this post
My Emacs Python environment
to be the most useful and comprehensive list of instructions and references on how to setup a decent Python development environment in Emacs regardless of OS platform. It is still a bit of work to setup but at least it covers the popular packages and components generally recommended for Python in Emacs that provide auto-completion functionality.
I loosely used this post as a guide to do the setup on my Windows machine with Emacs 23.2.1 and Python 2.6.5. Although, I also have Cygwin installed in some cases instead of running the *nix shell commands mentioned in the post, I just download the packages via a web browser, unzip them with 7zip, and copy them to my Emacs' plugin directory.
Also, to install Pymacs, Rope, and Ropemacs, I used Python's EasyInstall package manager. To use it, I downloaded and installed the setuptools package using the Windows install version. Once installed, at the command line, cd to their respective download locations and run the command
easy_install .
instead of the shell commands shown in the post.
Generally, I saved any *.el files in my ~\.emacs.d\plugins (e.g. in %USERPROFILE%\Application Data\.emacs.d\) and then updated my .emacs file to reference them as documented in the post.
Despite all this, on occasion, I've used DreamPie since it does have overall better auto-completion out of the box than my Emacs setup.
I'm spoiled by Intellisense too. The PyDev extensions for Eclipse offer a pretty good auto-complete substitute.
I find that PyDev + Eclipse can meet most of my needs. There is also PyCharm from the Intellij team. PyCharm has the added advantage of smooth integration with git.
I've been using PyScripter, an IDE for Windows, for a while now, and have found it very good. It has autocompletion among many other features. It's written in Delphi -- not that there's anything wrong with that -- it just bothers me a bit, though...
Take a look at Spyderlib, support most of the features including code completion
IMO, by far the easiest way to take advantage of the python tools available for emacs is to take advantage of the defaults that are all set up at:
https://github.com/gabrielelanaro/emacs-for-python
I actually took the time to get pymacs and ropemacs and python-mode all working independently before finding that little gem, and now I rely on it entirely for all my python based customizations. If you are new, I would definitely start there.
