hello, I have a question about try block. in this video, why do we put only
try:
amount_of_ticket = int(amount_of_ticket)
this line of code? why not like this?
try:
amount_of_ticket = input("Hello, {}! How many tickets would you like? ".format(user_name))
amount_of_ticket = int(amount_of_ticket)
can somebody let me know more clearly about try block? thank you.

try:
amount_of_ticket = input("Sorry about that {} Thats not a valid number. Please Try again").format(user_name)
amount_of_ticket = int(amount_of_ticket)
