Let's revisit the tweets dataframe containing the Russian tweets. In this exercise, you will compute the number of hashtags and mentions in each tweet by defining two functions count_hashtags() and count_mentions() respectively and applying them to the content feature of tweets.
In case you don't recall, the tweets are contained in the content feature of tweets.

# Function that returns numner of hashtags in a string
def count_hashtags(string):
# Split the string into words
words = string.split()
# Create a list of words that are hashtags

tweets['hashtag_count'] = tweets['content'].apply(count_hashtags)
tweets['hashtag_count'].hist()
