• Basic Python Programming Skills
• Basic Reddit Knowledge : Reddit is a network of communities based on people’s interests. Each of these communities is called a subreddit. Users can subscribe to multiple subreddits to post, comment and interact with them.
• A Reddit Account

To install PRAW, we run the following pip script on the terminal / command prompt.

pip install praw

After installing PRAW, we need to import it:

After importing PRAW, we need to instantiate it. There are 2 types of PRAW instances:

• Read-only Instance: With read-only instance we can only retrieve public information from Reddit. Information like top 10 posts from a certain subreddit. We can’t post material from this.
• Authorized Instance: With authorised instance we can do whatever a normal reddit account can do. Actions like comment, post, repost, upvote etc. can be performed.

Creating a read-only instance:

Output:

True

Creating an authorized instance:

Output:

False

To switch back to read-only mode:

Now let us see some of the operations we can acheive using PRAW:

• Access a Subreddit: In reddit there are multiple communities known as subreddits. We can obtain a subreddit instance using the method subreddit.

  This subreddit is for discussion of the GRE (Graduate Record Examination). If you're studying for the GRE, or can help people who are studying for the GRE, you're in the right place!

  #Rules
  
  - You must read and follow the rules!

• Access a Submission: Within a subreddit there are multiple post submissions. We can iterate through the submissions in the submission instance. Reddit provides us multiple ways to sort submissions:
  • rising
  • new
  • hot
  • gilded
  • controversial
  • top

  These methods will return a ListingGenerator, therefore we will need to iterate through it.
