Write the following Python program:

Get a string from the user.

If the string has less than $6$ characters, issue a warning and keep asking until the user gives a proper one.

Chop off the first two and the last two characters, print the remaining ones as a word.

Extract even positioned $,$ etc.$)$ characters from the string and print them as a word.

Remove all $\text{'}$a$\text{'}$s and $\text{'}$e$\text{'}$s from the string; print the rest.

Sample screen output:

Enter string: rome

String must have at least $6$ characters!

Enter string: tokyo

String must have at least $6$ characters!

Enter string: amsterdam
