Print it back out · Printing a name shows whatever value it currently holds.
Stores 0 under the name score · The equals sign stores the right side into the name on the left.
True · Assignment flows right to left: value into name.
player_score · Player score describes the value, while single letters hide meaning.
5 · The second assignment replaces the first, so score holds 5.
name = "Lia" · Text needs quotes, so only the quoted word counts as text. The bare forms are a number and a boolean.
False · Text needs quotes. Without them the code hunts for a variable named GrayFox and errors.
The old 0 is gone, so 5 prints · Reassignment replaces the old value, so the name holds 5 when printed.
