in the example, shouldn’t the term be value and not key?
from what i understand, it is like that in a dictionary:

Dictionary= { KEY: VALUE }

or are the two terms interchangeable? Thanks :slight_smile:

this one:

# A simple dictionary
d = {"foo" : "bar"}

for key in d: 
  print d[key]  # prints "bar"


All the terms are fine, we can loop over the dictionary, which gives use the keys, then we can use the key to get the value
