Add comments (text) via Python API

[rashmi_banthia]

Hello, 

I am trying to upload a string as a comment for one student, one submission using Python API. (I have Python 3) I am able to upload the file but not the string. 

Here's the code I have so far and it works for uploading file. I tried submission.edit() but couldn't get it to work. 

API_URL = 'https://canvas api url' ## Canvas API URL
API_KEY = "canvas api key" ## Canvas API key
COURSE_ID = 1234 #COURSEID 
ASSIGNMENT_ID = 123456 #Assignment ID 

canvas = Canvas(API_URL, API_KEY)
course = canvas.get_course(COURSE_ID)
assignment = course.get_assignment(ASSIGNMENT_ID)

submissionuser_234581 = assignment.get_submission(user = 12345)
submissionuser_234581.upload_comment(file='sample.txt')

Any help much appreciated. (If I have posted in wrong forum please let me know - first time post here)

Took me a long time as well, but this should work! This can't be combined with the file comment, so that will create two seperate comments.

submission.edit(submission={comment={'text_comment':'Write your comment here'})

Thank you so much for your solution! I have been looking everywhere to find a working example of how to set the comments in student's submission.

I do not know if the canvasapi changed but I had to adapt your row to the following statement to work:

submission.edit(comment={'text_comment':'Write your comment here'})

It worked. Thank you both. Could you also advise how to upload comments using an Excel spreadsheet or Txt file?

I've been thinking about writing something like this to return student work and came across your question.  How did you get an API?  Do you have to go through canvas or your school?
