Python supports a wide variety of string operations. Strings in Python are immutable, so a string operation such as a substitution of characters, that in other programming languages might alter the string in place, returns a new string in Python. Performance considerations sometimes push for using special techniques in programs that modify ...
Nim provides string interpolation via the strutils module. Formatted string literals inspired by Python F-string are provided via the strformat module, the strformat macro verifies that the format string is well-formed and well-typed, and then are expanded into Nim source code at compile-time.

String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
Python uses the + operator for string concatenation. Python uses the * operator for duplicating a string a specified number of times. The @ infix operator is intended to be used by libraries such as NumPy for matrix multiplication. [104] [105] The syntax :=, called the "walrus operator", was introduced in Python 3.8. It assigns values to ...

The term string also does not always refer to a sequence of Unicode characters, instead referring to a sequence of bytes. For example, x86-64 has string instructions to move, set, search, or compare a sequence of items, where an item could be 1, 2, 4, or 8 bytes long. [26]
The Americans, who were unbeaten during last year's gold-medal run, have brought back 10 players and coach David Carle this year. The tournament features the world's best under-20 players ...
