[RFE] Across: Add method description to all methods inside the cli-weather build

[vatsa287]

Request For Enhancement:

This feature would be useful for all hovers on methods on Text Editors. Give a good description of what the method does in brief.
First time contributors will be able to make this a Git practice.

Example:

from:

def get_basic_temparature(main_data, degree):
    data = main_data['data']
    city = data[0]['city_name']
    print("Current temparature in {} is {} {}" .format(city.capitalize(), data[0]['temp'], degree))

to:

def get_basic_temparature(main_data, degree):
    """ Display the current temperature with corresponding city name """
    data = main_data['data']
    city = data[0]['city_name']
    print("Current temparature in {} is {} {}" .format(city.capitalize(), data[0]['temp'], degree))
