Question

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 "<pyshell#0>", line 1, in <module>

    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'

Answer 1

code:

def safe_input():

try:

x = input()

#catching the exception the occured

except KeyboardInterrupt:

#set x value as none when InterruptedError

x = None

return x

x = safe_input()

print(x)

y = safe_input()

print(y)
