  • The slice() function returns a slice object that can use used to slice strings, lists, tuple etc. The slice object is used to slice a given sequence ( string , bytes , tuple , list or range ) or any object which supports sequence protocol (implements __getitem__() and __len__() method). Divide one mutable string slice into two at an index. The argument, mid, should be a byte offset from the start of the string. It must also be on the boundary of a UTF-8 code point. The two slices returned go from the start of the string slice to mid, and from mid to the end of the string slice.

Sep 28, 2016 · Specifying Stride while Slicing Strings. String slicing can accept a third parameter in addition to two index numbers. The third parameter specifies the stride, which refers to how many characters to move forward after the first character is retrieved from the string. So far, we have omitted the stride parameter, and Python defaults to the stride of 1, so that every character between two index numbers is retrieved.

Divide one mutable string slice into two at an index. The argument, mid, should be a byte offset from the start of the string. It must also be on the boundary of a UTF-8 code point. The two slices returned go from the start of the string slice to mid, and from mid to the end of the string slice.

In Swift 3.0, slicing a String produces a new String that is a view into a subrange of the original String's storage.

Operating on substrings is fast and efficient because a substring shares its storage with the original string. The Substring type presents the same interface as String, so you can avoid or defer any copying of the string’s contents.
