Writing to text file using python node

1

I am trying to export some formatted message from python node to a text file.

But I am not getting the output because of some error. I have pasted the screenshot of the code and the error in node.

Please help.!

While simply writing to a file e.g. ‘text.txt’ is valid for a normal python script, you need to provide the full path for writing in dynamo.

import sys
sys.path.append(r'C:\Program Files (x86)\IronPython 2.7\Lib')
import os

filedir = r'C:\test'
filename = 'text.txt'
filepath = os.path.join(filedir, filename)
message = 'example message’
with open(filepath, 'w') as f:
    f.write(message)

Hi All

I am trying to append text to a .txt file using python, but I can’t seem to get it to work.
This is something I have done several times before outside the Dynamo environment.
I even imported the entire boilerplate to see if I was missing anything, but that did not help.
What could I be missing?
See the code with the full boilerplate below.
Thanks for your help.

I figured it out, thanks.
I needed a file.close() after the file.write()
Thank you.
