It would be really handy to have a button to copy raw code from a Jupyter notebook to the clipboard so it can be dumped into a text file, .py/.R script, or straight into the terminal (a button like github has to copy to clipboard)
Does a button (or even a chrome add on) exist?
Obviously you could copy/paste sections manually into a txt file, but that's laborious for long notebooks/markdowns
Yes,there is a button:
File > Download as > Python (.py)
There is a more handy way for Mac OS users.
By installing an Automator script converting the ipynb file to py first, then automatically copy the content to the clipboard with one right-click and select the script in the Quick Action part.

You can use the magic command %%writefile to save as py file
%%writefile "directory/to/file/filename.py"
However, you should place this command at the top of the cell, otherwise it will throw an error.

I want to view the jupyter notebook in without having to execute, I mean no to open it and iteratively execute commands, just to see it as if it were a pdf or something like that.
I ask this because every time a want to see some code in the notebook I have to go to the specific directory and run the comand jupyter notebook and wait until it starts to be able to open the proper file.
If you are using Macos, give this a shot
Found in this thread:
A way to quick preview .ipynb files
You can view it nicely in PyCharm as well.
You can convert your notebook to html (or other formats) via
File -> Download as -> html
You can see them dropping the file on VSCode too.
I cloned a github repo using !git clone https://github.com/llSourcell/Pokemon_GAN.git. I wanted to modify a .py file inside Colab. So i used %load filename.py as suggested here (How to load/edit/run/save text files (.py) into an IPython notebook cell?). But whenever i run this command, i get disconnected after some time. I was wondering if there is some other way to edit .py file without undergoing the hassle of downloading it to pc,editing and then re uploading it.
In the early days of Colab you could have used Ipython magic commands. Use below command
%pycat code.py
A pop up will appear displaying the code. You can copy it and edit it locally.
Remove the file using below command
!rm code.py
Copy the edited code to a cell in notebook and add below command at the top of the cell
%%writefile code.py
Run the cell. A file will be created with the contents present in the cell.
Updates:
Now there are lot more easy and convenient options.
In the files section, there is an option to upload files or you can double click on the file, make changes and ctrl+s to save those changes.
You can also use https://github.com/abhishekkrthakur/colabcode to edit using visual studio code server.
Colab includes a text editor you can use to create, open, and delete .py files directly.
All is done in the Files view (see below).
To create or delete a file, right click and choose "New file" or "Delete file".
To edit a file, double click on it. It appears on the right portion of your screen. Make any changes you wish. Changes are saved automatically.
Unfortunately, it seems, colab do not support %load line magic (yet), and yet, you can see the file content using !cat your_file.py and then manually, copy the output contents, write them to a new cell and write %%writefile your_new_file_name.py at the top of the new cell to save this back to the instance. Note that, this will not be saved to your google drive yet.
Example:
!ls
output: colabData/
%%writefile something.py
print("everything's fine.")
!ls
output: colabData/ something.py
%run something.py
output: everything's fine.
you can edit it like this:
click on the triple bar (≡ on the left side of your windows)
click on files (the folder icon on the left)
click on Mount Drive and mount your drive
find your .py file and double click on it
edit it
press ctrl+s to save
edit:
these steps were after cloning your code into your drive
you should first mount your drive and clone your repo into your drive
Not a perfect solution but can be useful for someone.
You can use
!cat file_name.py to access file_name.py contents, copy the contents in the next cell and now you can run it or edit it.
I found it easier to edit the file locally.
You can download it from the left panel.
Right click on any file and download it.
Next, edit the file.
Next, upload the file.
use mv to move the file to the right location.
Solution:
p = """
Yadda yadda
whatever you want just don't use triple quotes.
"""
c = """text_file = open("text.text", "w+");text_file.write(p);text_file.close()"""
exec(c)
Easiest solution
just double click on the file you want to edit.The file opens and edit the file,save it and that's that.You are done
There is an app called Python Compiler Editor that you can connect to your Google Drive account, edit files and save them back.
The easiest way is:
1- Go to where you want the file to be with:
%cd WhereYouWantItToBe
2- Then write using:
%%writefile NameOfFile.txt
Hey there here is the start of the text
and also here
here is the end
3- Now run this cell and the file is going to be saved where you decided in step one.
While I don't have a way of editing in the notebook, I will share my pipeline.
Quite obvious really:
fork the repo or create a new one(for a new project)
create a branch just for uploading
make changes and push
evaluate
make changes
Hope that helps.
With the addition of the terminal (the icon is in the lower left corner), now we can edit files through vim.
You can open the file using the file explorer programatically, like this:
from google.colab import files
files.view('your_file.py')
It will open your file in a separate panel and you can then edit and save it there directly.
I'm using ipython notebook by connecting to a server
I don't know how to download a thing (data frame, .csv file,... for example) programatically to my local computer. Because I can't specific declare the path like C://user//... It will be downloaded to their machine not mine
Run this in separate cell in one of the notebooks:
!tar cvfz zipname.tar.gz *
To cover more folders up the tree, write ../ before the * for every step up the directory.
tar cvfz zipname.tar.gz ../../*
The file zipname.tar.gz will be saved in the same folder as your notebook.
Also if files size is too large execute the following in same notebook block
!split -b 200m allfiles.tar.gz allfiles.tar.gz.part
Alternatively you can use this extension https://github.com/data-8/nbzip
If you are using Jupyter notebook, you can go to the "File" tab on the top left part of the notebook and click "Open". It shows you the content of the current directory. You can select your data file with different format (CSV, text, etc) and then you can download it in your local computer.
Open tab in Jupyter notebook
Download your desired file
Based on another answer,
the following function will export a pandas data frame to a csv file and it will provide you with a link to download the csv file in your browser:
def csv_download_link(df, csv_file_name, delete_prompt=True):
"""Display a download link to load a data frame as csv from within a Jupyter notebook"""
df.to_csv(csv_file_name, index=False)
from IPython.display import FileLink
display(FileLink(csv_file_name))
if delete_prompt:
a = input('Press enter to delete the file after you have downloaded it.')
import os
os.remove(csv_file_name)
To get a link to a csv file, enter or import the above function and use the code below in a jupyter notebook cell :
csv_download_link(df, 'df.csv')
By default the argument delete_prompt=True makes sure that once you have downloaded the csv file, it gets deleted so the file doesn't pollute the git repository where you naturally archive your notebooks (converted in markdown format with jupytext for meaningful diffs).
The download option did not appear for me.
The solution was to open the file (which could not be correctly read as it was a binary file), and to download it from the notebook's notepad.
You can also download the files directly from the Jupyter dashboard. To open it, either click on the Jupyter icon in the top left corner, or alternatively select Open... from the File menu:
After the dashboard has opened, select the file you want to download by checking the check box to the left of it. A Download button will appear in the actions bar above:
I am using Enthought canopy for data analysis. I didn't find any option to create a .py file to write my code and save it for later use. I tried File> New >IPython Notebook, wrote my code and saved it. But the next time I opened it within Canopy editor, it wasn't editable. I need something like a Python shell where you just open a 'New Window', write all your code and press F5 to execute it. It could be saved for later use as well. Although pandas and numpy work in canopy editor, they are not recognized by Python shell (whenever I write import pandas as pd, it says no module named pandas). Please help.
Umair, ctrl + n or File > Python File will do what you want.
Best,
Jonathan
Let me add that if you need to open the file, even if it's a text file but you want to be able to run it as a Python file (or whatever language format) just look at the bottom of the Canopy window and select the language you want to use. In some cases it may default to just text. Click it and select the language you want. Once you've done that, you'll see that the run button will be active and the command appear in their respective color.
I am trying to write the Python BPY -code inside Blender and noticed some editor -mode (source) and, instead of reinventing the wheel, I want to use my Vim -syntax-highlighting-etc inside Blender -text-editor. So how can I use Vim inside Blender?
You can write scripts either in an external text editor, or in
Blender's built in text editor. Move to a panel you wish to change to
be the text editor, click the editor select button and choose "text
editor" (shortcut) SHIFT+F11. Click the + New button at the bottom.
If you want, you can enable line numbers and syntax coloring with the
buttons at the bottom. Create a new script with File → New, paste the
code below into it, and save it. Or alternatively, paste the code
below into a file, and open that file with File → Open in Blender. As
name choose something with the extension .py, for example
wikibooks.py. Put it into Blender's user scripts path.
From the source you provided it looks to me that it doesn't matter what text editor you use as long as you save the python scripts to the file locations provided in that documentation (e.g. ~/.blender/scripts and other OS paths). Not very familiar with blender since I'm answering via the vim tag. Looks like there's potentially a plugin to use an external editor: http://www.blendernation.com/2011/08/02/edit-blender-text-files-using-external-text-editor-plug-in/. Also if you're on Mac then look into QuickCursor: http://www.hogbaysoftware.com/products/quickcursor/.
