Augmented assignment (or compound assignment) is the name given to certain assignment operators in certain programming languages (especially those derived from C).An augmented assignment is generally used to replace a statement where an operator takes a variable as one of its arguments and then assigns the result back to the same variable.
The boolean values True and False were added to the language in Python 2.2.1 as constants (subclassed from 1 and 0) and were changed to be full blown keywords in Python 3. The binary comparison operators such as == and > return either True or False.

The second most commonly used notation is [1] x := expr (originally ALGOL 1958, popularised by Pascal). [2] Many other notations are also in use. In some languages, the symbol used is regarded as an operator (meaning that the assignment statement as a whole returns a value). Other languages define assignment as a statement (meaning that it ...
The basic arithmetic operators are normally all left-associative, [1] which means that 1-2-3 = (1-2)-3 ≠ 1-(2-3), for instance. This does not hold true for higher operators. For example, exponentiation is normally right-associative in mathematics, [1] but is implemented as left-associative in some computer applications like Excel. In ...
For Q3, Volkswagen reported operating profit that slid 42% to 2.86 billion euros ($3.1 billion), though revenue only fell 0.5%. More worrisome was the operating margin falling to 3.6%, down from 6 ...
Calling f with a regular function argument first applies this function to the value 2, then returns 3. However, when f is passed to call/cc (as in the last line of the example), applying the parameter (the continuation) to 2 forces execution of the program to jump to the point where call/cc was called, and causes call/cc to return the value 2.
