I downloaded mini conda. I'm very new to programming. How do I access the download to actually begin to write code? I've read to do it in the command prompt, but is there a seperate place to write the code, sort of how the r programming environment opens up a window for me to write in?
Mini Conda is a package manager so it's just there to help you install/manage packages and setup your python environment. You can write your code in whatever editor you want such as vim, atom, or even text edit.

This seems like a basic question, but I can't seem to find a setting/process for it.
In VSCode's Python extension, there is an option to right-click (or keyboard shortcut) in the editor and Run Current File in Python Interactive Window. This works great.
Is there a way to Run Main File in Python Interactive Window so to speak? If you are building a package/module and are making changing in a non-main file, you currently need to switch back to that main file editor tab before running it as described above.
It would be nice to link module/package files to run the main file from anywhere in the package and not have to switch files in the editor. This would make building/debugging a separate module file much faster using the Python Interactive Window. Thanks
Create a launch option that names the main python file instead of the current file and choose it in the debug/run sidebar.
You might need to set the cwd property to the correct value.
Now when you press F5 the main python file is run.
So Im very new to programming and computers in general... Over the last couple months i have learned everything i know on my phone using Dcoder with android. I have been searching for a program that is similar but on a laptop that can compile my .py files. So i downloaded Atom and have installed atom-python-run and other packages to run my code through the terminal (even though I would rather it compile like on Dcoder) but it says that python is not a file... so i changed the path in the control panel to the right folder but now it says no pyvenv.cfg file... in cmd it doesnt work when i type in python but it works when i type in py... idk
honestly if anyone knows how i can get a program like dcoder on my laptop i would greatly appreciate it... i am way more familiar with phones than i am with laptops... but im trying to learn.
I have tried everything. This is my last hope before giving up
error message one on atom: windows cannot find python make sure you have spelled it right
is there anyway to just get it to search for py????
If you want to run python using the Atom editor you must first load python into Atom. This is simple. Go to this site and install the extension 'laungage python'. Then search for and install the package 'Script'. Script will successfully run your python files. Run Atom and enter your python file. Then go to the packages menu and click on Script. I haven't been able to get Python Runner or Code runner to run my python files, only Script.
Dcoder has a web app also at https://code.dcoder.tech, Dcoder uses cloud storage, makes it easier to switch between phone and laptop to code when needed.
I just started learning Python last week to automate some stuff I do (thanks to automatetheboringstuff.com). Assume I know nothing about programming. The only thing I know is HTML and CSS.
I created a simple automation workflow already and I want to improve not the code (maybe in the future because it's not yet finished) but how I can maintain my setup/program on two laptops -- Both Mac OS running on High Sierra.
I have a .py file that contains my automated workflow. I don't know where to place it. It currently resides in my Dropbox so i can use it on laptop1 and laptop2.
I also created a virtualenv for each machine and did the requirements.txt thing as well (just to prep for the future). The directory is on both username/python/project_name.
I read in some posts that these files and other resources can exist anywhere whether inside each virtualenv or not. And that it's just a preference. I also read that the virtualenv itself isn't recommended to be placed inside apps like Dropbox (that's why i separated it on each laptop).
I switch between both laptops frequently. The environment which contains the packages doesn't really concern me that much when switching. It's the other files that is bothering me. For example, there's an image I need, this has to be available on both laptops so my solution to this is to have a Resources folder inside Dropbox as well. It currently looks like this:
Dropbox
Projects
Project 1 files (images, etc.)
Project 2 files (images, etc.)
Workflows (this would contain my completed .py files)
I read some stuff about the virtualenvwrapper, but haven't looked at it yet. Maybe in the future when i do have more projects to manage. Because right now, it's just this one.
Lastly, I noticed that every time i open up Terminal and activate my virtualenv, the file directory is in Users/username
How can i set it to default to Dropbox/Projects/project_name? I always have to set it using the chdir(). That way, when i do have multiple projects (and virtualenv) i don't have to worry about where the files load/ save.
Finally, how do I run the .py script? If i open the IDLE, open the .py file there, and use f5, it runs properly. But as far as I know, that doesn't look into the virtualenv i setup. Is that correct?
I tried right-clicking, then Open With > Python Launcher the .py file. and i'm getting an error saying there are no modules found. It seems it's not loading the right virtualenv. So there must be something wrong with the file i made.
Then I read about the #! you place at the beginning of the .py files but i don't understand it. Can someone explain that further? Is that why my file isn't loading properly?
Thanks for helping out!
You can run .py scripts from the command line using:
python test.py
That tells terminal to run test.py in the python interpreter and send the output to your terminal, just like when you run it in the IDLE. If your .py script is not in your current directory and you don't want to change directories, you can access it using it's absolute path:
python /Users/username/Dropbox/Workflows/test.py
As long as you have already activated your virtualenv, it should run your script using only the libraries you have added to your virtualenv. Also, once your virtualenv is activated, you can move around directories using "cd" and it will bring your virtualenv with you.
I have a number of python files with .py extensions that I was working on, closed, and tried to come back to later. When I tried to open them by right clicking and selecting “Edit with IDLE,” instead of opening a pycache folder was created.
I have a work around in which I go to edit the file with Notepad++, copy the text into a new python editor, delete the old file, and resave the new file with the same name. My research has turned up questions related to pycache and IDLE, but none specifically addressing the issue. Has anyone encountered a similar problem/know how to solve it? I’m running Python 3.5.2 on Windows 7.
What did you name the .py file as? If you named it something like "string.py", Python might interpret the file as one of those in the "Lib" folder. Why you can resave it with the same name and have it working afterwards is anyone's guess. I suggest just renaming the python file to something else.
I developed the bad habit of writing/editing python files with IDLE from watching intro videos when I was still relatively new to programming. I have since learned that file editors like Sublime or IDE's like PyCharm are a significantly better way to go and would highly recommend anyone reading this.
I had a similar issue. When I clicked "Edit with IDLE 3.6", it would create a "pycache" folder and not open the python file on IDLE.
I found a Reddit thread that gives an explanation here.
The reason the pycache folder is created is as follows:
When you import a module, Python stores the compiled bytecode in that
directory so that future imports can use it directly, rather than
having to parse and compile the source again. It does not do that for
merely running a script, only when a file is imported.
No such folder is created for the standard library, as the standard
library is pre-cached when you install Python
I was importing Python's "random" library, in another python file (placed in the same directory). So the issue was solved once I deleted that file.
Sorry if my questions are extremely stupid, but I'm quite at a loss while trying to use Python from Ubuntu Linux. My friend installed the Pycharm for me. I can go without using any commands, to files-->Pycharm projects---> click on one project and see the files, which I can open.
But I'm lost as of how to compile and run the files and see the output at this step? The .py files saved before (written with hello world and some really simple ones) are opening, but how can I see the output?
Also, when I go to the programs by files-->Pycharm projects---> file1.py, file 2.py...etc., do we code and run them from the terminal, using the Linux features? If not, how can I do all of the coding and running from the terminal?
Many thanks!!!
I'm not sure what you mean but "how can I do all of the coding and running from the terminal?" you can use nano to edit to code and run the code on the terminal too
