Answer 1

Answer:

See below.

Explanation:

The code given is,

a = [ int( a ) for a in input( ).strip( ).split( ' ' ) ]

The code takes in an input (  as a String ). This String is then splitted into parts which are separated by spaces( for example "23 34 45" becomes [ 23 , 34 , 45 ] ).

Going in deep,

int( a ) : It ensures that the String block ( the splitted part ) has an integer data type.

input( ).strip( ).split( ' ' ) : Takes an input, removes empty spaces from the beginning and end, and finally splits it by spaces ( ' ' )

All these integers are then stored in a list.

Try this,

>>> a = [ int( a ) for a in input('Input ').strip().split(' ')]

Input 45 67 89

>>> print( a )

[45, 67, 89]
