Let's now breakthrough out more inside information on this subject.
What is the assignment expression syntax in Python?
Python 3.8, released in October 2019, adds assignment expressions to Python via the := syntax. The assignment expression syntax is also sometimes called “the walrus operator” because := vaguely resembles a walrus with tusks. Assignment expressions allow variable assignments to occur inside of larger expressions.
Which is the most efficient assignment expression in Python?
The more efficient rewrite would have been: In most contexts where arbitrary Python expressions can be used, a named expression can appear. This is of the form NAME := expr where expr is any valid Python expression other than an unparenthesized tuple, and NAME is an identifier.
Do you parenthesize the assignment operator in Python?
To preserve backwards compatibility, assignment operator usage inside of f-strings must be parenthesized. As noted above, this usage of the assignment operator is not recommended. An assignment expression does not introduce a new scope. In most cases the scope in which the target will be bound is self-explanatory: it is the current scope.
Which is an example of an assignment expression?
Assignment expressions allow you to assign and return a value in the same expression. For example, if you want to assign to a variable and print its value, then you typically do something like this:
