I'm just getting into programming and took the common advice of using a free text editor with python. I seem to be running into a problem and everything I've tried so far hasn't worked.
I downloaded Anaconda from this url and whenever I put the location of python.exe into the run bar: C:\Users\Home\Anaconda2\python.exe all I get is the python console to pop up. I've tried adding: "$(FULL_CURRENT_PATH)" to the end as one user had suggested, but that just opens up the console and closes it immediately after. Any idea what I'm doing wrong?
First, I usually create a space for all my projects. Usually C:\projects so it's easy to find. Then I create a folder for specific work. I'd do C:\projects\learningPython.
Now, create a new file and save it to C:\projects\learningPython\hello-world.py
In the file put this line
print('Hello World!')
Then click save.
Now open a command prompt (enter cmd in the run bar)
now enter this in the command prompt:
python C:\projects\learningPython\hello-world.py
Hopefully this will work for you. Let me know if you do not see 'Hello World' appear on the command prompt.
After you followed nlloyd instructions and you are assured that your setup works and you can use Python from the commandline, I would use the nppexec Plugin to integrate Python (and other external tools) with notepad++ . (You can get it from Notepad++ PluginCentral or directly via the Plugins -> PluginManager.)
There I would create a nppexec script: with the following lines (use Plugins -> NppExec -> Execute... ):
npp_save
C:\Tools\Python\Python.exe $(FULL_CURRENT_PATH)
change C:\Tools\Python\Python.exe to whereever you have installed python
save this nppexec script
use the commands Execute... and Direct execute previous from Plugins -> Nppexec menu to select the nppexec script (if you have several) and repeatedly use the same nppexec script

Path must be messed up and I can't fix it.
In the command prompt I am trying to open and run a python program that I made in IDLE. I am running Python 3.8.5. According to Automate the Boring Stuff, I should just be able to do:
py birthdays.py
But when I do that I get:
C:\Users\name\AppData\Local\Programs\Python\Python38-32\python.exe: can't open file 'birtdays.py': [Errno 2] No such file or directory
All of my scripts are located in: C:\Users\henri\AppData\Local\Programs\Python\Python38-32.
The only thing that I could think of is that it is going one step too far and searching in python.exe instead of just Python38-32. But Ii'm not even sure it works like that.
I tried to add the exact path using:
set PATH=%PATH%;C:\Users\name\AppData\Local\Programs\Python\Python38-32
But when I do this and press enter nothing happens.
when I want to use CMD to run python scripts, I just use
cd\
to back the main root of drive C. then use
cd folderAddress
for several time until to reach the exact scrip containing folder. Finally, I type
python scriptName.py
In your command prompt type python.The output should be python 3.** (depending on your python version).
If you see the python version it's working fine. In command prompt navigate to the folder that you have your python file using cmd command. then type
python birtdays.py
Don't forget the space after python.
I have made a Python program that uses output.to_csv('results.csv'). When I run it in Spyder it creates that CSV file. But when I double click on it nothing happens. Cmd appears and closes but nothing on the folder, no results.csv.
What am I missing? What more do I have to do?
Run the program from the command line itself instead of double-clicking the .py file.
I assume you are on Windows since you mention CMD. First, cd into the directory containing your program. Then, run python <program>.py or python3 <program>.py depending on your installation.
This time, you will see any output or error messages that appear in CMD without it immediately closing.
If the .csv file really exists, you should be able to go to your File Explorer and find the file at the top of the "Quick Access" section. Right-click the file and hover over "Open With >". Then select Notepad and a notepad will open up showing your results.
If you do not see the file, then try running your program on the command prompt (for Windows):
Press the windows key and type "cmd" in the search bar.
Choose "Command Prompt"
Go to the dir of your program using the cd command
Type python <program name>.py
If there are no errors, follow the steps in the first paragraph.
Ok i guess windows is not recommended at all for this type of tasks. I mean running something simple as create such file is like trying to kill the Lernaean Hydra.
What i did is i just runned it with anaconda prompt and it worked sweet! Thanks for help. Thanks to all!
PS: I'm seriously considering changing to Linux after this
For anyone having the same problem, but have anaconda installed. 1) Open Anaconda Prompt, 2) use cd (1 space) then adress of the folder which contains your py program (eg. cd C:\Users\Bernie\Desktop\tasos) and hit enter, 3) on the next line that appears type: python program_name.py, 4)Hit enter, 5)success!
I am well aware of the thread How to execute Python code from within Visual Studio Code
But none of them shows how to get the >>> python shell running with the file imported. Cuz I would like to call functions separately.
I understand that I can get the python shell going by simply typling python in the terminal but the functions in the python file have to manually imported everytime.
Is there a way to run files in VSCode like in IDLE?
you can run the file in an interactive mode in VSC code terminal by using the parameter -i :
python -i py_file.py
Install the Python Extension, then press Ctrl+Shift+P (Command+Shift+P) and type Python: Start REPL. Click the command, and you'll get an interactive Python console.
Assuming you have the official Python extension installed, you can search the command list (Ctrl+Shift+P) for "Python interactive" and you'll see several options that allow to do different variations of this:
Not sure if this was figured out or not, but I was having a similar question. How to simply use something like IDLE (the known '>>>' shell prompt) inside VSCodesee w/o chasing down plugins and their settings? I noticed that no answer was marked confirmed and although insightful, not what I was looking for.
I use Mac and while trying different things to address this, I found that by using/copying the path in the Python Launcher settings I got what I was looking for. Then, I validated the equivalent for Windows. Please see below.
Windows:
If you are using Windows, from your Terminal pane/window in VSCode, enter the path to your python.exe, including the executable name. It is located within the "User > AppData" directory.
For example: C:\Users\YOUR_USER_ID\AppData\Local\Programs\Python\Python310\python.exe
Note that AppData is a hidden folder, so may have to change your view settings in Explorer to show Hidden Items.
MAC:
If you are using MAC, from your Terminal pane/window in VSCode, enter the path to your interpreter
For example: /usr/local/bin/python3
Note: You can also do this directly from a CMD, PowerShell or a Terminal(Mac) window without having to launch IDLE, VSCode or any other coding/scripting app.
To build on the answer already provided, you can automatically run in interactive mode by changing your settings:
Go under File>Preferences>Settings. Search for "arguments" in the search bar. Then under "Python › Terminal: Launch Args", click on the link "Edit in settings.json".
Once settings.json is open, add "-i" with the quotation marks. It should look something like that:
{
"workbench.colorTheme": "Default High Contrast",
"terminal.integrated.localEchoEnabled": "off",
"terminal.integrated.shellIntegration.enabled": false,
"python.terminal.launchArgs": [
"-i"
]
}
Now, it will pass the argument -i every time you run.
I installed Blender 2.6 and I'm trying to run a script called drawcar.py (Which uses PyOpenGL)
I looked around the documentation for importing a script and could only access Blender's python console.
How do I run drawcar.py from the Linux terminal with Blender?
You can also execute the following code in the python console to execute an external script without opening it up in the text editor:
filename = "/full/path/to/myscript.py"
exec(compile(open(filename).read(), filename, 'exec'))
The above code comes from the following link:
Blender - Tips and Tricks
Open a Text Editor view in Blender.
Press Alt + O, or go to Text>Open Text Block and open the .py file
Then simply press Run script :D
P.s. Instead of opening a file in step 2, you can also hit the "+ New" button and create a new script instead.
Note : In newer versions the Run Script button label has been replaced with a Play icon :
this answer is too late, but to help anyone with the same problem
via the terminal:
blender yourblendfilenameorpath --python drawcar.py
from the man pages
-P or --python <filename>
Run the given Python script file.
To run a script by another script or from console:
import bpy
script = bpy.data.texts["script_name.py"]
exec(script.as_string())
It is likely that drawcar.py is trying to perform pyOpenGL commands inside Blender, and that won't work without modification. I suspect you are getting some import errors too (if you look at the command console). Blender has it's own internal python wrapper for opengl called bgl, which does include a lot of the opengl standards, but all prefixed by bgl.
If you have a link to drawcar.py I can have a look at it and tell you what's going on.
How do I run a Python file from the Windows Command Line (cmd.exe) so that I won't have to re-enter the code each time?
Wouldn't you simply save your Python code into a file, and then execute that file using Python?
Save your code into a file called Test.py.
And then run it?
$ C:\Python24\Python.exe C:\Temp\Test.py
If you don't want to install an IDE, you can also use IDLE which includes a Python editor and a console to test things out, this is part of the standard installation.
If you installed the python.org version, you will see an IDLE (Python GUI) in your start menu. I would recommend adding it to your Quick Launch or your desktop - whatever you are most familiar with. Then right-click on the shortcut you have created and change the "Start in" directory to your project directory or a place you can mess with, not the installation directory which is the default place and probably a bad idea.
When you double-click the shortcut it will launch IDLE, a console in which you can type in Python command and have history, completion, colours and so on. You can also start an editor to create a program file (like mentioned in the other posts). There is even a debugger.
If you saved your application in "test.py", you can start it from the editor itself. Or from the console with execfile("test.py"), import test (if that is a module), or finally from the debugger.
If you put the Python executable (python.exe) on your path, you can invoke your script using python script.py where script.py is the Python file that you want to execute.
Open a command prompt, by pressing Win+R and writing cmd in that , navigate to the script directory , and write : python script.py
A good tool to have is the IPython shell. Not only can it run your program (%run command), but it offers also many tools for using Python interactively in an efficient manner (automatic completion, syntax coloring, quick access to the documentation, good interaction with Matplotlib,…). After you install it, you'll have access to its shell in the Start menu.
You need to create environment variables. Follow the instructions here: http://www.voidspace.org.uk/python/articles/command_line.shtml#environment-variables
In DOS you can use edit to create/modify text files, then execute them by typing python [yourfile]
