Writing and reading existing txt. file

Is there an easy way to read and write specific lines from an existing txt file in python grasshopper?
Thanks in advance!

You can use the built-in open() function to open a file object, and then use the read() or write() method to read from or write to the file

# To read from a text file
with open('file.txt', 'r') as file:
    data = file.read()

# To write to a text file
with open('file.txt', 'w') as file:
    file.write('Hello, world!')

Keep in mind that if the data changes while your gh is running, you have to re-read the file.

Thanks! And for example reading a specific line would be?:

with open('file.txt', 'r') as file:
    data = file.readline(1)

You can Write to a .txt file then Read in vanilla GH as well.

Yes, unfortunately I need to read/write within a python loop. I think doing it within python is easier then, right?

To read a specific line from a text file, you can use the readlines() method to get a list of all the lines in the file, and then access the specific line by its index.

with open('file.txt', 'r') as file:
    lines = file.readlines()
    third_line = lines[2] #reads the 3rd line in the doc

I’ve seen the Stream option in the context menu of a panel before but never tried it until now. This is a simple way to output certain results.

Could this be tweaked so streaming would be possible to an Excel file?

CSV offers a bit more structure.
