Split a list into half by even and odd indexes in python?

Split a list into half by even and odd indexes in python?

You can split a list into two separate lists based on even and odd indexes in Python using list slicing. Here's how you can do it:

original_list = [1, 2, 3, 4, 5, 6, 7, 8] # Split the list into even and odd indexed elements even_indexed = original_list[::2] odd_indexed = original_list[1::2] print("Even indexed elements:", even_indexed) print("Odd indexed elements:", odd_indexed)

In this code:

  • even_indexed contains the elements from the original list with even indexes (0, 2, 4, 6).
  • odd_indexed contains the elements from the original list with odd indexes (1, 3, 5, 7).

You can replace original_list with your list of values. This method works for both even and odd-length lists.
