Answer 2

string = input("Enter a string: ")

print("It's alternate characters are: ", string[::2])

The above program is done using string slicing, which the act of extracting a substring from a given string.

A slice function follows a similar syntax:

string_name[start:stop:step]

• start - indicates from which index value it must traverse.
• stop - indicates till which index value it must stop traversing.
• step - indicates by how many characters it must skip when traversing.

We've given the step value here as 2. This means, it will display the characters after every 2 characters, which is displaying the alternate characters.
