The operator allows for initializing a variable via a single statement which otherwise might require multiple statements Although python allows multiple assignments as each assignment were an expression, this is simply a special case of the assignment statement built into the language grammar rather than a true expression. Use in variable assignment reduces the probability of a bug from a faulty assignment as the assigned variable is stated only once
Python syntax and semantics a snippet of python code demonstrating binary search the syntax of the python programming language is the set of rules that defines how a python program will be written and interpreted (by both the runtime system and by human readers) A notable example of this is python, where = is not an operator, but rather just a separator in the assignment statement The python language has many similarities to perl, c, and java.
In most imperative programming languages, the assignment statement (or expression) is a fundamental construct. Python 3.8 introduced assignment expressions, but uses the walrus operator := instead of a regular equal sign (=) to avoid bugs which simply confuse == with = A good example is in python, which has several such constructs [5] since assignments are statements, not operations, the assignment operator does not have a value and is not associative
Augmented assignment (or compound assignment) is the name given to certain assignment operators in certain programming languages (especially those derived from c).
