Class not working

Class not working due to the following reasons:

# the **"self"** key word was not defined in init method
# It does not have **"get_data()"** method but **"get_tweets()"**
# the "data/ethiopia_covid19_23june2020.json" does not exist in the directory but "covid19_23june2020.json"
# A **cvs file** was parsed instead of **json file**
