6:29 You said each key/value pair is a tuple. Tuples can't be modified. So how can you modify a value in a dictionary?

dave i have a question why in the order print band in 18:52 didn`t print the first band in the program and printed the one we just made it

[lsteved]

band["vocals"] = "Coverdale" Boo! haha
Seriously though, great lessons.. and the Zeppelin examples actually helped!

[hussainalaa]

i put in (morenums) numbers like (98, 71, 51, and others), the sets doesnt set them in order in the (nums), it changes its order.

[johnaweiss]

22:53 You didn't test to see if `0 in nums` will find the False.

[ivanshugaev]

is "print(band["vocals"])" and "print(band.get("guitar"))" interchangeable?
