Answer 3

the value of any letter is called by SCRABBLE_LETTER_VALUES [l] where "l" is the letter.

Answer 4

Ok. Dictionary is a structure that maps keys to values. Each key can have only one value associated with it (that value can be a list or some other structure though).

In Python, if 'd' is a dictionary, then expression 'd[k]' yields a value associated with key 'k' if that key is present in 'd' - otherwise an exception is thrown.

Symmetrically, an expression 'd[k] = v' assigns value 'v' to the key 'k'.

In that exercise you're given a pre-populated dictionary that has all the letters as keys, and each of them is associated with a score.

Is it clear now?
