In Reddit, we can post a comment to any submission, we can also comment on a comment to create a thread of comments. We can either upvote or downvote a comment. Here we will see how to downvote a comment using PRAW. We will be using the downvote() method of the Comment class to downvote a comment.

downvote()

Syntax : downvote()
Parameters : None
Returns : Nothing

Example 1 : Consider the following comment :

The ID of the comment is : fvib7aw

# importing the module
import praw

# initialize with appropriate values
client_id = ""
client_secret = ""
username = ""
password = ""
user_agent = ""

# creating an authorized reddit instance
reddit = praw.Reddit(client_id = client_id,
                     client_secret = client_secret,
                     username = username,
                     password = password,
                     user_agent = user_agent)

# the ID of the comment
comment_id = "fvib7aw"

# instantiating the Comment class
comment = reddit.comment(comment_id)

print("Score before downvoting : " + str(comment.score))

# downvoting the comment
comment.downvote()

print("Score after downvoting : " + str(comment.score))

Output :

Score before downvoting: 25
Score after downvoting: 24

Example 2 : Consider the following comment:

The ID of the comment is : fv9qvgo

# importing the module
import praw

# initialize with appropriate values

reddit = praw.Reddit(client_id = client_id,
                     client_secret = client_secret,
                     username = username,
                     password = password,
                     user_agent = user_agent)

# the ID of the comment

print("Score before downvoting : " + str(comment.score))
