16 paź 2012 · The slice of s from i to j with step k is defined as the sequence of items with index x = i + n*k such that 0 <= n < (j-i)/k. In other words, the indices are i, i+k, i+2*k, i+3*k and so on, stopping when j is reached (but never including j). If i or j is greater than len (s), use len (s).
String Slicing in Python can be done using the slice operator [:] or the slice() function. Let's see how to use them with multiple examples.
