10a: in-class assignment 4

• Prep: 09:00-09:40 (40 mins)
• Break: 09:40-09:55 (15 mins)
• Regular time: 09:55 - 10:35 (40 mins)
• Extra time: 09:55 - 10:45 (50 mins)

Take a look at this dictionary:

populations = {"France" : 68000000,
        "Netherlands": 18000000,
        "Belgium" : 11700000,
        "Germany" : 83000000}

Use Python to create a .txt file with on every line one key-value pair, like this:

France,68000000
Netherlands,18000000
Belgium,11700000
Germany,83000000

Then write a function that takes the path to this .txt file as input, and outputs a list that contains four sublists, with each sublist consisting of the country and its population. Like this:

[["France",68000000],["Netherlands",18000000],["Belgium",11700000],["Germany",83000000]]
