Sometimes, while working with the Jupyter notebook you need to create a file, like a .py file. Today we will show how to create files within Jupyter using the magic cells.
Write files from Jupyter
We can simply type %%writefile myfile within a Jupyter cell and then start writing the file. For example:
%%writefile myfile.py
def my_function():
print("Hello from a function")
will create a new file called myfile.py
If we want to see the content of the file we can type !cat myfile.py and we get:
Append files from Jupyter
Now, let’s say that we want to add something to our file. We can use the parameter -a which comes from the append.
For example, if we want to add the my_function() to our file:
%%writefile -a myfile.py my_function()
As we can see, we added the my_function() to the myfile.py
Run the Script from Jupyter
We can simply use the command !python myfile.py or alternatively to type %run -i myfile.py
