The increment operator is represented by two plus signs in a row. Examples: counter = counter + 1; counter += 1; counter++; ++counter; As statements, the four examples all do the same thing. They add 1 to the value of whatever is stored in counter. The decrement operator is represented by two minus signs in a row.4. Python 3.8+ has the walrus operator, which allows you to assign to a variable within an expression. The expression var := expr assigns the value of expr to var, and results in that same value. This means the pre-increment operator ++var can be simulated in Python by var := var + 1. This increments var and the result is the new, …The new “walrus operator” in Python 3.8, written as :=, has been much discussed.
