How to edit and save text files (.py) in Google Colab?

问题

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. Thanks in advance.

回答1:

You can use 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.

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.

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.

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)

I found it easier to edit the file locally.

1. You can download it from the left panel.
2. Right click on any file and download it.
3. Next, edit the file.
4. Next, upload the file.
5. use mv to move the file to the right location.

回答6:

Colab includes a text editor you can use to create, open, and delete .py files directly.

For example:

There is an app called Python Compiler Editor that you can connect to your Google Drive account, edit files and save them back.

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.
