Python 3.7.3

If you type Ctrl-C while the shell is executing the input() function, a KeyboardInterrupt exception will be raised. For example:

>>> x = input()

Traceback (most recent call last):

File "", line 1, in

x = input()

KeyboardInterrupt

>>>

Create a wrapper function safe_input() which works just like the function input() except that it returns nothing when an exception is raised.

>>> x = safe_input() # Typing Ctrl-C

>>> x # x is None

>>> x = safe_input() # Typing 45

45

>>> x # x is 45

'45'
