Day 6: Olympic Medals – have fun(?) with dictionaries

This program sorts the number of Olympic Medals won by each nation in descending order.

Countries and numbers of Medals are stored in a dictionary

This is what the output looks like (the screenshot shows only half of the list, but you get the picture):

 

 

Considered that this program basically only needed four lines of code it took me a long while to figure it out.

 

I wanted to sort the dictionary by its value: The number of medails. In the beginning the numbers in the

dictionary (that I got from Wikipedia) were stored as strings like this:

 

medails = {
     "Country A" = "1",
     "Country B" = "8",
     "Country C" = "11
}

 

It turned out that it would sort “1, “11” and than “8” – well because it is a string and not a number.

So I tried to store one medail number as an Integer, just to try it out but that throwed me an error. It turned out I had to turn all strings

into Integers first and then it would sort properly – even though the Python-Docs say you can mix any sort of values in a dictionary.

 

The program itself looks like this:

from medails_dictionary import medails # thats where I stored the dictionary

# sort the dictionary by its number values in decending order
c = sorted(medails.items(),key=lambda x: x[1], reverse=True)

# go through every key and print the key-value-pair
for x in c:
    print (x)

 

The dictionary looks like this:
