Exceptions in Python

Try and except

    try:
        value = int(input('Enter a natural number: '))
        print('The reciprocal of', value, 'is', 1/value)        
    except:
        print('I do not know what to do.')

Two exceptions after one try

    try:
        value = int(input('Enter a natural number: '))
        print('The reciprocal of', value, 'is', 1/value)        
    except ValueError:
        print('I do not know what to do.')    
    except ZeroDivisionError:
        print('Division by zero is not allowed in our Universe.') 

refer q1.py

the default except

    try:
        value = int(input('Enter a natural number: '))
        print('The reciprocal of', value, 'is', 1/value)        
    except ValueError:
        print('I do not know what to do.')    
    except ZeroDivisionError:
        print('Division by zero is not allowed in our Universe.')    
    except:
        print('Something strange has happened here... Sorry!')
