0x16. API advanced

0-subs.py

Write a function that queries the Reddit API and returns the number of subscribers (not active users, total subscribers) for a given subreddit. If an invalid subreddit is given, the function should return 0.

Hint: No authentication is necessary for most features of the Reddit API. If you’re getting errors related to Too Many Requests, ensure you’re setting a custom User-Agent.

Requirements:

• Prototype: def number_of_subscribers(subreddit)
• If not a valid subreddit, return 0.
• NOTE: Invalid subreddits may return a redirect to search results. Ensure that you are not following redirects.

1-top_ten.py

Write a function that queries the Reddit API and prints the titles of the first 10 hot posts listed for a given subreddit.

Requirements:

• Prototype: def top_ten(subreddit)
• If not a valid subreddit, print None.
• NOTE: Invalid subreddits may return a redirect to search results. Ensure that you are not following redirects.

2-recurse.py

Write a recursive function that queries the Reddit API and returns a list containing the titles of all hot articles for a given subreddit. If no results are found for the given subreddit, the function should return None.

Hint: The Reddit API uses pagination for separating pages of responses.

Requirements:

• Prototype: def recurse(subreddit, hot_list=[])
• Note: You may change the prototype, but it must be able to be called with just a subreddit supplied. AKA you can add a counter, but it must work without supplying a starting value in the main.
• If not a valid subreddit, return None.
• NOTE: Invalid subreddits may return a redirect to search results. Ensure that you are not following redirects.

Your code will NOT pass if you are using a loop and not recursively calling the function! This /can/ be done with a loop but the point is to use a recursive function. :)

100-count.py

Write a recursive function that queries the Reddit API, parses the title of all hot articles, and prints a sorted count of given keywords (case-insensitive, delimited by spaces. Javascript should count as javascript, but java should not).

Requirements:

• Prototype: def count_words(subreddit, word_list)
• Note: You may change the prototype, but it must be able to be called with just a subreddit supplied and a list of keywords. AKA you can add a counter or anything else, but the function must work without supplying a starting value in the main.
• If word_list contains the same word (case-insensitive), the final count should be the sum of each duplicate (example below with java)
• Results should be printed in descending order, by the count, and if the count is the same for separate keywords, they should then be sorted alphabetically (ascending, from A to Z). Words with no matches should be skipped and not printed. Words must be printed in lowercase.
• Results are based on the number of times a keyword appears, not titles it appears in. java java java counts as 3 separate occurrences of java.
• To make life easier, java. or java! or java_ should not count as java
• If no posts match or the subreddit is invalid, print nothing.
• NOTE: Invalid subreddits may return a redirect to search results. Ensure that you are NOT following redirects.

Your code will NOT pass if you are using a loop and not recursively calling the function! This /can/ be done with a loop but the point is to use a recursive function. :)
