How to properly catch this exception

[pyzyx3qwerty]

The way you use except is wrong - The except block lets you handle the error. So for example

try:
  print(x)
except NameError:
  print("Variable x is not defined")
except:
  print("Something else went wrong")

Here, the variable x is not defined, and therefore, a Nameerror will come like

Error:
Variable x not defined

like that
here, even if the input is greater than 1, an error will not come.
You will have to use a while loop like

while Score > 1:
    Score = input('enter number between 0 and 1\n')

Then print your rest of the code. The while loop will work as long as your score is greater than 1. When it becomes less than 1, it will automatically break
