Question

In Python And Use List comprehension to solve this question

Given a file like this:

Blake 4

Bolt 1

De Grasse 3

Gatlin 2

Simbine 5

Youssef Meite 6

Your program when completed should produce output like this:

>>>

In the 2016 100 yard dash the top finishers were:

Blake

Bolt

De Grasse

Gatlin

Simbine

Youssef Meite

The people with a two part name are: ['De Grasse', 'Youssef Meite']

The top three finishers were: ['Bolt', 'De Grasse', 'Gatlin']

Your mission will be to do the following:

1. Develop algorithms to solve all remaining steps in this problem.

2. Use a list comprehension to load the data from a file named “runners.txt”.

3. Use the information read in from the file to print out the names of the top 6 finishers formatted as shown in the example above.

4. Use a list comprehension to create a list of the names that have two parts to them.

5. Use a list comprehension to create a list of the people who finished in the top the positions.
