How Can I Use An Exception Inside An While Loop? List Index Out Of Range

I have the following function: def findTweetWith100PlusRTs(): global tweet_main while tweet[tweet_main]['retweet_count'] < 100: tweet_main += 1 It loops through

Solution 1:

While you can make this work, you should be using a for loop:

# this is a proper use of while! :-)whileTrue:
    for current_tweet in tweet:
        if current_tweet["retweet_count"] < 100:
            # do something with current_tweetpass

    time.sleep(120)
    refreshTL() # make sure you put a new list in `tweet[tweet_main]`

If, as can be guessed, refreshTL() adds more tweets, you should read on generators and iterators, which are what you want to be using.

A very simple example of an endless tweet generator would be:

deftweets_generator():
    tweets = NonewhileTrue:
        # populate geneartor
        tweets = fetch_tweets()
        for tweet in tweets:
            # give back one tweetyield tweet
        # out of tweets, go back to re-populate generator...

The generator is constantly re-filled with tweets if you implement fetch_tweets. Now you can do something like:

# only take tweets that have less than 100 retweets thanks @Stuart
tg = (tweet for tweet tweet_generator() if tweet['retweet_count'] < 100)
for tweet intg:# do something with tweet

Solution 2:

You could do it like this

deffindTweetWith100PlusRTs():
    global tweet_main
    whileTrue:
        try:
            if tweet[tweet_main]["retweet_count"] >= 100:
                breakexcept IndexError:
            # do something
        tweet_main += 1
