When I start a python project in vs code (with the microsoft python extension) it starts "Analyzing in the background" and python keep crashing. It also uses a ton of memory.
Anyone knows how to fix this? Or is it supposed to do this?
This seems to have fixed it for me: https://github.com/Microsoft/vscode-python/issues/4990#issuecomment-477628947
You can disable the new Python Language Server by opening settings in VSCode (Ctrl+, ) and set "python.jediEnabled": true. Then reload the window and/or restart VSCode.
I had the same issue; the only solution that worked for me was to open settings.json (ctrl + Shift + P) and change
"python.languageServer": "Microsoft"
to
"python.languageServer": "Pylance"
Then one gets a pop-up that asks whether one wants to reload the window which one should confirm by pressing "OK".
Then everything works normally again (IntelliJ, autocomplete etc).
As #Vasco pointed out in the comments Microsoft is no longer supported as explained in this thread.

Jedi is an autocompletion tool for Python that can be used in IDEs/editors. Jedi works. Jedi is fast. It understands all of the basic Python syntax elements including many builtin functions. So you can switch Jedi instead of Python Language Server.
Process:
set "python.jediEnabled": true
disable the Visual Studio IntelliCode plugin
delete the .vscode directory
Can solve this by either disabling the extension as suggested in previous answers, or excluding large directories (e.g. containing data) from its search path, by adding to your workspace settings an python.workspaceSymbols.exclusionPatterns key, like so:
settings.json:
{
"python.workspaceSymbols.exclusionPatterns": [
"**/site-packages/**",
"your_pattern_or_directory_to_exclude"
]
}
See also the vscode extension docs.
Here is how I solved this issue:
Go to File > Preferences > Settings > TYPE "python.language server"
If set to 'Microsoft' change your language server to 'Pylance'
Python: Language Server
Define Type of the Language Server
SELECT: Pylance
Reload your Visual Studio Code
Try importing your libraries causing the issues again:
import numpy as np
import pandas as pd

This is the code I have:
import pygame
pygame.init()
I'm very confused because if I try to run the file, then there seems to be no issue, but pylint says the following:
E1101:Module 'pygame' has no 'init' member
I have searched thoroughly for a solution to this "error". In every relevant case I found, the solution was to make sure that I have not made another file or folder with the name "pygame", because in that case, I would just be importing my own file or folder.
However, I have not made a folder or file with a name even close to "pygame", so I don't know what the problem is.
As said earlier, it seems like I'm able to run the file without any issues and having errors like this confuses me in my learning process.
I write code in Visual Studio Code, I'm using python 3.6, I'm using pygame 1.9.3 and have updated my pylint. Any help would be appreciated.
Summarizing all answers.
This is a security measure to not load non-default C extensions.
You can white-list specific extension(s).
Open user settings and add the following between {}:
"python.linting.pylintArgs": [
"--extension-pkg-whitelist=extensionname" // comma separated
]
You can allow to "unsafe load" all extensions.
Open user settings and add the following between {}:
"python.linting.pylintArgs": [
"--unsafe-load-any-extension=y"
]
If you have VS code, go in your .vscode folder > settings.json or search for python.linting.mypyArgs Under user settings tab paste inbetween curly braces
"python.linting.pylintArgs": [
"--extension-pkg-whitelist=lxml" // The extension is "lxml" not "1xml"
]
I no longer see the pyinit error.
I had the same issue when I started using Visual Studio Code with Python. It has nothing to do with having another pygame.py or not installing it properly. It has to do with the fact that Visual Studio Code takes your code literally, and since you cannot import pygame.init(), it thinks that it isn't a correct module.
To fix this, open up settings.json (go into your settings, and click the {} icon) and paste
"python.linting.pylintArgs": [
"--extension-pkg-whitelist=pygame"
]
to it.
I had the same issue with one of my modules. This is what I did to resolve the problem. (I'm using visual studio on windows 10)
Press CTRL+SHIFT+P in visual studio
Choose "Preferences: Open Settings (JSON)"
Add "python.linting.pylintArgs": ["--generate-members"] below one of the lines (put a comma if necessary)
Save the .json file (CTRL+S)
For me, the code looks like this :
{
"breadcrumbs.enabled": false,
"editor.minimap.enabled": false,
"python.pythonPath": "C:\\Users\\xxx\\Anaconda3",
"terminal.integrated.rendererType": "dom",
"window.menuBarVisibility": "default",
"workbench.activityBar.visible": false,
"workbench.statusBar.visible": true,
"python.linting.pylintArgs": ["--generate-members"], //line to add
"[json]": {
}
}
Hope it helps.

This answer includes the answer to your question. In short it explains:
Pylint imports modules to effectively identify valid methods and attributes. It was decided that importing c extensions that are not part of the python stdlib is a security risk and could introduce malicious code.
and as a solution it mentions, among others:
Disable safety using the .pylintrc setting unsafe-load-any-extensions=yes.
See here for more information about pylint.rc. Quickest method is to just create the file .pylintrc in your project directory or your home directory.
I found adding this in settings.json() solves the problem.
"python.linting.pylintArgs":[
"--extension-pkg-whitelist=pygame",
"--erros-only"
]
I find an answer and it really works for me.
See the accepted answer and change it to extension-pkg-whitelist=lxml
pylint 1.4 reports E1101(no-member) on all C extensions
I recommend going to the view tab, clicking command palette and searching preferences: open settings.json. Then add a comma on the last line of code.Below that paste this:
"python.linting.pylintArgs": [
"--extension-pkg-whitelist=extensionname" // comma separated
]
Then save your document (ctrl + s).
Check if you have a python file named pygame.py created by you in your directory. If you do, then the import pygame line is importing your own file instead of the real Pygame module. Since you don't have an init() function in that file, you're seeing this particular error message.
I found a solution, modifying the most voted answer:
"python.linting.pylintArgs": [
"--extension-pkg-whitelist=pygame"
]
Replaced the "lxml" with "pygame".
Disable Pylint
1.Press ctrl + shift + p
2.Then type Disable Pylint
If you are using vscode then you can go to settings:
python.linting.pylintEnabled = False
It will fix the problem. If you aren't using vscode then you can go the command prompt and manually uninstall pylint with the command
pip uninstall pylint.

I'm completely new to Python and PyCharm and I cannot figure out why PyCharm doesn't auto-completes very simple cases such as:
import pickle
pickle.dum[control+space or control+shift+space results nothing here]
I have PyCharm 2.6.2 and Python 2.7.1. What's wrong?
Add:
I'm on Mac OS 10.7.3
Can't reproduce. Make sure you have a valid Python interpreter configured for the project. Also try File | Invalidate Caches.
My experience is if you turn ON the File -> Power-Save Mode, all background tasks will be stopped, including the Auto-Complete task.
So you can try turning off the Power-Save Mode.
You could try with a virtualenv and on it install all you project dependencies and the go to pycharm preferences/Project Interpreter and it will update your project dependencies.
Project Inspector
I changed the projector interpreter and it works fine now.
It happened to me, too.
But all the previous answers don't solve my issue.
The weird thing is when I am coding, it will pump out the autocomplete for me. But once I leave the autocomplete mode, I cannot reproduce the autocomplete by typing Ctrl + Space.
So the work I already surveyed are
Make sure the config(e.g., virtualenv) is right in Pycharm
Make sure Pycharm can show autocomplete
Make sure I am not in the Power Safe Mode
Finally I solved this just because my shortcut of switch language in the Mac is also Ctrl + Space, so it's kind of override my shortcut in the Pycharm. I change the shortcut in the Pycharm by changing in Pycharm-> Preference-> Keymap-> Main menu-> Code-> Completion ->Basic
Then the problem is solved
Is it possible?
By debug I mean setting breakpoints, inspect values and advance step by step.
You can do remote debugging of python web apps over TCP/IP with winpdb.
(Link appears down as of June 2019. Try PyPI winpdb)
I haven't used web2py, but if it runs in a terminal window, you can use standard pdb stuff. Add this line somewhere in your code:
import pdb; pdb.set_trace()
This will invoke the debugger and break. Then you can use PDB commands: n to step to the next line, l to list code, s to step into a function, p to print values, etc.
One can debug applications built on Web2py using the following set-up:
Eclipse IDE
Install Pydev into Eclipse
Set Breakpoints on your code as needed
Within Eclipse right-click the file web2py.py and select Debug As -> Python Run
When a breakpoint is hit Eclipse will jump to the breakpoint where you can inspect variables and step thru the code
You can also use Visual Studio 2010. Here's how:
Download and install Python Tools for Visual Studio.
Create a new project from existing code (File > New > Project From Existing Code...)
Specify your web2py folder and use the defaults.
Right-click on web2py.py and choose Set as Startup File.
Set breakpoints and hit F5 (run) or right-click on web2py.py and choose Start with Debugging.
This is a nice setup if you already use visual studio.
Yes, it is possible, Due to the "span prevention" I am still not allowed to post screenshots, but here is a full screenshot hosted at my website:
http://static.techfuel.net/debug_web2py.png
I'm debugging web2py applications with Eclipse and PyDev. Here is an article:
http://www.web2pyslices.com/main/slices/take_slice/2
Here is an article on debugging python with pdb, which will work with web2py. http://sontek.net/debugging-python-with-pdb
As Carl stated, it is as easy as:
Installing PyDev in Eclipse
Right Click on your Web2Py project, selecting Debug As > Python Run
Selecting web2py.py as the file to run
No other plugins or downloads are needed.
#Ned Batchelder is almost right, but the standard way of doing it in web2py is slightly different.
Instead of `import pdb; pdb.set_trace(), you use the code:
from gluon.debug import dbg
dbg.set_trace()
When executing the web application, the application will freeze when it reaches this section of code. You then go to http://127.0.0.1:8000/admin/debug/interact (using the root URL for your application) and it will show a fully interactive, web based debugger:
See documentation.
