Python core 43.2 the command "except:" does not work?

Question

My code is below:

coffee = ["Café Latte", "Caffe Americano", "Espresso", "Cappuccino", "Macchiato"]
choice = int(input())
try:
a = len(coffee)
b = a-1
if 0<=choice<=b:
print(coffee[choice])
# your code goes here
except:
print('Invalid number')
# and here
finally:
print('Have a good day')

When entering a number between 0 and 4, everything is fine. But if you enter a different number, it just prints what should be printed after the "finally:"

I went through the task using code that is written below, but I would like to know what my mistake. Thanks.

coffee = ["Café Latte", "Caffe Americano", "Espresso", "Cappuccino", "Macchiato"]
choice = int(input())
a = len(coffee)
b = a-1
if 0<=choice<=b:
print(coffee[choice])
else:
print('Invalid number')
print('Have a good day')

The except function was never called because nothing tripped the try section.

You have an if clause which will produce a result if the choice is within the coffee range.

else -> NOTHING

Answer 2

Let's say I added "else:" to show an empty line on the screen.

coffee = ["Café Latte", "Caffe Americano", "Espresso", "Cappuccino", "Macchiato"]
choice = int(input())
try:
a = len(coffee)
b = a-1
if 0<=choice<=b:
print(coffee[choice])
else: print()
except:
print('Invalid number')
finally:
print('Have a good day')

Nothing happens)

Even in the code below, nothing happens if I understand correctly how it works

a = int(input())
try:
a == 2
except:
print('Invalid number')

Most likely somewhere my mistake, but I do not know where, or I do not understand how it should work

By creating the if statement, the code now looks for an option outside the range of the coffee list, which is usually handled by the else statement.

I have a little code below which will explain, I hope

coffee = ["Café Latte", "Caffe Americano", "Espresso", "Cappuccino", "Macchiato"]
choice = int(input())
try:
print(coffee[choice])
except:
print('Invalid number')
finally:
print('Have a good day')

Answer 4

Totalt new at this but I think you can make it work in a easier way:

coffee = ["Café Latte", "Caffe Americano", "Espresso", "Cappuccino", "Macchiato"]

choice = int(input())

try:

print(coffee[choice])
except:
print("Invalid number")
finally:
print("Have a good day")
