Extra terristrial

Question

x =str(input())
y=x[100::-1]
print(y)
How this code is working?? 🧐🧐

Answer 1

Yashwanth Kiran ,

the line that may confuse us is:

y=x[100::-1]

it is a slice that is applied to the input string stored in x. it is working with positive and negative numbers as slice arguments.

i would recommend you to read more about this topic:

=> btw: the task description for the mentioned exercise requires to reverse a string. this can be done by just using: y=x[::-1]

Answer 2

X is assigned to the input received. Then element in 100th index and all indexes which comes before of string x are taken , and reversed, then assigned to variable y. Finally it's printed.
Extra:- python always takes inputs as strings. You don't need to convert it again to string in line 1.
