A simple python program that shows the ranking of countries based on population growth.

Lab 6

This assignment is based on Textbook P8.17 and P8.18. The input file lab6Input.txt is fromhttps://www.cia.gov/library/publications/resources/the-world-factbook/rankorder/2002rank.html. It shows the ranking of countries based on population growth.

The program has a main function that calls the following 3 functions:

A function to read from the lab6input.txt file, which is a text version of the population growth page above. Each line of the file has 3 fields, separated by colon ( : ).Parse or separate each line of data and store the country name as a key and the growth rate as value in a dictionary. The ranking field is discarded. The input file should only be accessed by this function, so don’t open the file again after this function.
Since some of the country names may be difficult for the user to remember the exact spelling (Herzegovina? Vanuatu?), whenever the user enters a single letter at the search prompt, print all the country names that have the same starting letter. To do this, write a function that creates a dictionary with keys that are first letters of the countries, and the value of each key is a set of country names with the same starting letter. For example, the key ‘Z’ has a value which is the set (Zambia, Zimbabwe).
A function that loops to let the user enters in a full country name or a letter. If the user enters a name, print the corresponding growth rate. If the user enters a letter, print the set of country names that have a matching starting letter. If the name or the letter (both case insensitive) doesn’t exist, print an error message.
