Python Challenge Solution

Difficult challenge :/ I can usually get most of it but struggled. Still have questions after watching Ken's approach

I think the part I'm most confused on is:

player_number = 1
for player in players:
    print("Player {}: {}".format(player_number, player))
    player_number += 1

I somewhat remember "+=" to add to the number. I thought we did this in the Ticket Project but looking through my notes and code I'm not finding it.

Would someone be able to explain why Ken used this?

You're exactly correct. The += operator is known as the addition assignment operator and causes the value on the right to be added to (and stored back into) the value on the left.

In essence, variable += value is a shorthand for variable = variable + value.

As used here, it is incrementing the player number to display with each player in the list.
