Scraping Reddit using Python

  • Difficulty Level : Hard

In this article, we are going to see how to scrape Reddit using Python, here we will be using python’s PRAW (Python Reddit API Wrapper) module to scrape the data. Praw is an acronym Python Reddit API wrapper, it allows Reddit API through Python scripts.


To install PRAW, run the following commands on the command prompt:

pip install praw

Creating a Reddit App

Step 1: To extract data from Reddit, we need to create a Reddit app. You can create a new Reddit app(

Reddit – Create an App

Step 2: Click on “are you a developer? create an app…”.

Step 3: A form like this will show up on your screen. Enter the name and description of your choice. In the redirect uri box, enter http://localhost:8080

App Form

Step 4: After entering the details, click on “create app”.

Developed Application

The Reddit app has been created. Now, we can use python and praw to scrape data from Reddit. Note down the client_id, secret, and user_agent values. These values will be used to connect to Reddit using python.

Creating a PRAW Instance

In order to connect to Reddit, we need to create a praw instance. There are 2 types of praw instances:  

  • Read-only Instance: Using read-only instances, we can only scrape publicly available information on Reddit. For example, retrieving the top 5 posts from a particular subreddit.
  • Authorized Instance: Using an authorized instance, you can do everything you do with your Reddit account. Actions like upvote, post, comment, etc., can be performed.


# Read-only instance
reddit_read_only = praw.Reddit(client_id="",         # your client id
                               client_secret="",      # your client secret
                               user_agent="")        # your user agent
# Authorized instance
reddit_authorized = praw.Reddit(client_id="",         # your client id
                                client_secret="",      # your client secret
                                user_agent="",        # your user agent
                                username="",        # your reddit username
                                password="")        # your reddit password

Now that we have created an instance, we can use Reddit’s API to extract data. In this tutorial, we will be only using the read-only instance.

Scraping Reddit Subreddits

There are different ways of extracting data from a subreddit. The posts in a subreddit are sorted as hot, new, top, controversial, etc. You can use any sorting method of your choice.

Let’s extract some information from the redditdev subreddit.


import praw
import pandas as pd
reddit_read_only = praw.Reddit(client_id="",         # your client id
                               client_secret="",      # your client secret
                               user_agent="")        # your user agent
subreddit = reddit_read_only.subreddit("redditdev")
# Display the name of the Subreddit
print("Display Name:", subreddit.display_name)
# Display the title of the Subreddit
print("Title:", subreddit.title)
# Display the description of the Subreddit
print("Description:", subreddit.description)


Name, Title, and Description

Now let’s extract 5 hot posts from the Python subreddit:


subreddit = reddit_read_only.subreddit("Python")
for post in


Top 5 hot posts

We will now save the top posts of the python subreddit in a pandas data frame:


posts ="month")
# Scraping the top posts of the current month
posts_dict = {"Title": [], "Post Text": [],
              "ID": [], "Score": [],
              "Total Comments": [], "Post URL": []
for post in posts:
    # Title of each post
    # Text inside a post
    posts_dict["Post Text"].append(post.selftext)
    # Unique ID of each post
    # The score of a post
    # Total number of comments inside the post
    posts_dict["Total Comments"].append(post.num_comments)
    # URL of each post
    posts_dict["Post URL"].append(post.url)
# Saving the data in a pandas dataframe
top_posts = pd.DataFrame(posts_dict)


top posts of the python subreddit

Exporting Data to a CSV File:


import pandas as pd
top_posts.to_csv("Top Posts.csv", index=True)


CSV File of Top Posts

Scraping Reddit Posts:

To extract data from Reddit posts, we need the URL of the post. Once we have the URL, we need to create a submission object.


import praw
import pandas as pd
reddit_read_only = praw.Reddit(client_id="",         # your client id
                               client_secret="",      # your client secret
                               user_agent="")        # your user agent
# URL of the post
url = "\
# Creating a submission object
submission = reddit_read_only.submission(url=url)

We will extract the best comments from the post we have selected. We will need the MoreComments object from the praw module. To extract the comments, we will use a for-loop on the submission object. All the comments will be added to the post_comments list. We will also add an if-statement in the for-loop to check whether any comment has the object type of more comments. If it does, it means that our post has more comments available. So we will add these comments to our list as well. Finally, we will convert the list into a pandas data frame.


from praw.models import MoreComments
post_comments = []
for comment in submission.comments:
    if type(comment) == MoreComments:
# creating a dataframe
comments_df = pd.DataFrame(post_comments, columns=['comment'])


list into a pandas dataframe
