Exceptions

In Python all exceptions are sub-classes of Exception class.

Trying to open a file that does not exist:

try:
    file = open('example2.txt', 'r')
    print('file content >>', file.read())
    file.close()
except NameError:
    print('NameError raised!')
except Exception as e:
    print(e)
finally:
    print('this will be printed anyway!')

Output:

[Errno 2] No such file or directory: 'example2.txt'
this will be printed anyway!
