How do I enable indentation in Visual Studio Code?
I'm trying to learn Python (new to programming) and need auto-indentation. It worked with the first version I tried, but it doesn't indent after a colon (:) any more. How can I configure it to automatically indent?
You can install the Visual Studio Code Python extension which will provide intellisense, auto-completion, code formatting, and debugging.
Here is more information on the Python extension, here.
As said there is the Python extension which now do it out of the box, but still don't do a great job, and an example is when you copy and past a whole block into a function or so. It just indents the first line, and that's not a good behavior. Here are two good helpful solutions:
indent a whole block manually: select the whole block, and then click Tab. If you want to indent backward, you do it with Shift+Tab. That's it, and I think that can be useful in several places.
Python auto indent extension (https://marketplace.visualstudio.com/items?itemName=hyesun.py-paste-indent). It solves the problem when pasting. Just see how it works in the link. Now about setting it up: You need to set just one keybinding for the command "pyPasteIndent.pasteAndIndent" provided by the extension. Once done, you will have your own shortcut to paste and indent automatically (I have set it to Alt + P)
Here is how:
- Ctrl+SHIFT+P to open the command palette, then write "key"*, choose *"open keyboard shortcut", and then the keybinding page open, which it's the nice interface for the **keybindings.json. You can open keybindings.json the same way and by choosing "open keyboard shortcut file" (in place of just "open keyboard shortcut"). Give it a look if never have. But here I will go with the nice interface. Know also that you can open that going menu File → Preference → Keyboard Shortcut.
In the keybinding window, in the search bar, paste pyPasteIndent.pasteAndIndent, and then click the + button to add the shortcut and create the keybinding.
The image below shows well how it's done:
I installed this extension: Python Indent. It works very well.
Simple solution!
Click the tab size (may show "Spaces: 4") in the bottom right corner and choose Convert Indentation to Tabs or Convert Indentation to Spaces as per your requirement.
I faced similar issues while editing. Select the lines of code you wish to intend and press Ctrl + ] in Windows or CMD+] on Mac.
You can change the indent size in settings. Search for tab size in settings. I use two, by the way.
I faced similar issues switching from PyCharm. The Python Indent extension, which is available in the Visual Studio Code marketplace, works perfectly fine for me.
For me, "Convert Indentation to Tabs" has worked.
To do that:
Go to "Command Palette" Ctrl+Shift+P (View>Command Palette)
Type in & select "Convert Indentation to Tabs" and press Enter

I'm using pyton with VSC and ran into a problem while watching a tutorial; when highlighting a number in brackets, the data type doesn't show up, while it does in the tutorial. IE: when higlighting 4.5 in
print(4.5), it should say 4.5: float in a popup, but that doesn't happen. Can anybody help me?
Visual Studio Code does not have automatic intellisense, you need to download a language specific extention to use it.
Steps to download:
open the extentions menu located on the left toolbar (ctrl-shift-x).
search for python.
click install on the top result.
(optional) restart VSC, I don't know if it is necessary, but better safe then sorry.
I hope this fixes your problem :) .
Edit: I just checked, and after installing the extention will say something along the lines of 'reload to enable extention', if it does not, it doesn't need it. Otherwise, just click the text that says that.
When I use Jupyter Notebook inside the browser or inside Google Colab I can comment multiple lines of code by selecting them and pressing crtl + #. This also sometimes worked in Visual Code and not only for Python but also for C++ (of course then each line began with a //). However, I have no idea what enabled this behavior and how to reproduce it, it was very convenient. If you have any idea how to enable this, I would very much appreciate your help.
In VS Code you can use Ctrl+/ for comment multiple lines and Alt+Shift+A for block comment .
By default, using Ctrl+/ for commenting a single line and Shift+Alt+A for commenting line blocks.
If you want to override this and make a shortcut on your own, press Ctrl+Shift+P to open the Command Palette and search Open Keyboard Shortcuts (JSON). After that, VSCode opens a JSON file where you can put your own shortcut.
{
"key": "Ctrl+Shift+3", // Shift+3 for selecting #
"command": "editor.action.blockComment" // or editor.action.commentLine
}
Add this code snippet inside the square brackets and save the file.
Is there a way to copy text out of Python IDLE on a Mac? When I highlight text and copy then past into a text editor, I get the same text pasted. It is some of the first text I start with in IDLE. None of the other text will copy out.
From The Things I Hate About IDLE That I Wish Someone Would Fix (from 2011):
1.2) NEW FEATURE: Auto-Copy-On-Highlight
Once we get rid of being able to move the cursor off the last line, that opens a new opportunity to implement an automatic copy-on-highlight feature that many terminal and IRC client programs implement. Since this text is read-only, the only reason a person has for highlighting it is to copy it (they can’t delete it.) As soon as the user highlights text in the shell window, it is copied to the clipboard.
Looks like the best you can do is save as a .py file. Open that in a text editor and continue working in IDLE. With each save, the text editor will refresh with all updates, including errors. At least TextWrangler will.
Sometimes in things like a linux terminal you can't do a normal copy and paste, try holding Command/Control + Shift + C after highlighting things and seeing if that works, since you're on mac i'm not sure if it would be the Command or Control key so try both
EDIT: There is an apple discussion about the exact same thing. They discuss going into the options menu, then into configuration and navigating to the keys section. Then you use a built in key-set, their suggestion is using IDLE Classic Mac.
I cannot tell from your description exactly what you did and what happened. But I can recommend that you upgrade to 3.4.4 or 3.5.1 (or 2.7.11 for 2.7 users). Among other improvements, they all contain a patch to make right-click for context menu work on Mac Aqua. This was issue 24801 on the CPython bug tracker.
If there is still an actual problem on Mac, I would like to know so it can be fixed.
Every time I open a Python file PyCharm will hide all imports and shows:
import ...
within the editor.
I have to manually unfold it to see the imports. Where do I find the setting to undo auto-hiding of import statements?
As this question may be useful for people who also are not looking for the term "code folding", I'll make my comment an answer.
As extracted from IntelliJ IDE Web Help, but also worked on PyCharm CE 3.4.1:
Open the IDE Settings (File > Settings, or Ctrl+Alt+S).
Under the "Editor" node, click "General" and then "Code Folding". The "Code Folding" page is displayed.
In the "Collapse by default list", select the check boxes to the left of the code constructs you want to be displayed collapsed. So here you can uncheck "Imports".
Apply changes.
The image below shows what it looks like:
Actually in pycharm 2016.1 it's Editor -> General -> Code Folding
I'm just starting out learning python with GEdit plus various plugins as my IDE.
Visual Studio/F# has a feature which permits the highlighting on a piece of text in the code window which then, on a keypress, gets executed in the F# console.
Is there a similar facility/plugin which would enable this sort of behaviour for GEdit/Python? I do have various execution type plugins (Run In Python,Better Python Console) but they don't give me this particular behaviour - or at least I'm not sure how to configure them to give me this. I find it useful because in learning python, I have some test code I want to execute particular individual lines or small segments of code (rather then a complete file) to try and understand what they are doing (and the copy/paste can get a bit tiresome)
... or perhaps there is a better way to do code exploration?
Many thx
Simon
Yes, you use "external tools plugin"
http://live.gnome.org/Gedit/ToolLauncherPlugin
As an example,
Edit > Preferences
Plugins
Tick "External Tools"
Close the Preferences Window
Tools > Manage External Tools
Click the "Add new too" icon in the bottom left
Name it "Execute Highlighted Python Code"
give it a keyboard shortcut
change the input combo box to : "highlighted selection"
change the output to : "Display in Bottom Pane"
In the editor window for the tool, replace everything with :
.
#!/usr/bin/env python
import sys
result = eval(sys.stdin.read())
print expression, "=>", result, type(result)
.
If you wish to see the result of entire .py file, you can put this code in your new created external tool window
#!/usr/bin/env python
import sys
exec(sys.stdin.read())
and change the Input to Current document.
For python, You can use "external tools plugin":
#!/bin/sh
python3 "$GEDIT_CURRENT_DOCUMENT_PATH"
Option of external tool:
Save: Current Document
Input: Current Document
Output: Display in bottom panel
Language: Python or Python3
Don't forget the quotes around $GEDIT_CURRENT_DOCUMENT_PATH....
To answer your second question, and hopefully guide you in a direction you'll be happier with, I think you ought to consider trying some different editors. There are many with more powerful code exploration features than GEdit has. Check out this post:
What IDE to use for Python?
I installed iPython console in gedit and do most of my simple scripting in it, but gedit is a very simple editor, so it'll not have some advance feature like an IDE
But if you want code exploring, or auto completion, I recommend a real IDE like Eclipse.
If you just want a editor, KomodoEdit is fine.
What I do is keep a file called python_temp.py. I have a shortcut to it in my dock. I use it as a scratch pad. Whenever I want to quickly run some code, I copy the code, click the shortcut in the doc, paste in the text and hit f5 to run. Quick, easy, simple, flexible.
I think what you're looking for is http://live.gnome.org/Gedit/Plugins/BetterPythonConsole.
You hit F5 and it runs the code in your file in a IDLE-like console. I don't know if it can only run selected code. (I don't think it can) but you can always copy the needed code in a new window and run it from there.
Have a look through the plugin list for other interesting stuff: http://live.gnome.org/Gedit/Plugins
The closest to a decent IDE...
Install gedit-developer-plugins (through synaptic || apt-get) and don't forget to enable (what you need) from gEdit's plugins (Edit->Preferences [tab] plugins) and happy coding
