It seems that rpartition creates an extra tuple object, which has a cost, but the cost is apparently less than the cost of doing two explicit slices in Python. This is shown in the following diagram: Similarly, 1:6:2 specifies a slice starting with the second character (index 1) and ending with the last character, and again the stride value 2 causes every other character to be skipped: The illustrative REPL code is shown here: As with any slicing, the first and second indices can be omitted, and default to the first and last characters respectively: You can specify a negative stride value as well, in which case Python steps backward through the string. @AmpiSevere try calling the function like this: How Intuit democratizes AI development across teams through reusability. Here is another way to achieve the same thing: It's easier to write a straight function shifttext(text, shift). Python supports another binary sequence type called the bytearray.
