A clear description and example of closures, which can be very confusing at first when you're a beginner.

Closures are easier in VBA. It's called a static variable. No need for child functions. It's just a normal function-scoped variable who's value persists between calls.

4:17 If you know there's exactly one coin, you don't have to say
str(coins)
you can just say
one

I like this kind of games example where we keep refactoring the code as we learn more and more.
16:23 Unless it's intended I think there is no need for "\n" in lines 62 and 63 (Trying to save some spaces😁)
Thanks Dave,

How is this useful? It would seem to be similar to a class but only one method is allowed to be used. The function variable is initialized with 3 coins. Is it simply to set initial values, then make changes to the values as the closure function is called? To count something up? or down? Such as the amount of coins.

I made small changes and I think closure is more like OOP classes but In FP way :D

"""
def new_amusement_arcade(name='anonymous', coins=0):
def play_game():
nonlocal coins
coins -= 1

print(f'\n{name} has {coins} {"coin" if coins == 1 else "coins"} left.' if coins >= 1 else f'\n{name} is out of coins.')

return play_game


tommy_play_game = new_amusement_arcade(name="Tommy", coins=3)
jenny_play_game = new_amusement_arcade(name="Jenny", coins=5)

tommy_play_game()
tommy_play_game()

jenny_play_game()

tommy_play_game()
"""

Hi! Can you make a video on calculation a cube volume, plotting it and rotating horizontally 360 degree? That will be helpful...

thank you mr dave i learned a lot from you

Using an f-string would have been much simpler in the print statement.
