Assignment Operations
An assignment statement evaluates the expression and assigns the result to the target. Augmented assignment is the combination, in a single statement, of an operation and an assignment statement.
a = 3
b = 2
a += b # a = 5
a -= b # a = 3
a *= b # a = 6
a /= b # a = 3.0
a //= b # a = 0.0
a %= b # a = 1.0
a **= b # a = 1.0
