Answer:
None of the statement a to d can be considered accurate because for:
a) Since assignment is Non associative operator in python, addition and subtraction will be evaluated first before assignment.
b) While Exponent operator has right-to-left associativity in Python, assignment do not have associativity. therefore, both of them are not left associative
c) The operator with highest precedence is Parentheses not Exponentiation
d) The statement is false because it is correct to say "Multiplication have higher precedence than addition and subtraction" and therefore evaluated first, not unary multiplication
Explanation:
Precedence in Python
Precedence guides the order in which operation are carried out in python.
for example
in 8 - 4 * 2, multiplication is evaluated first because it has higher precedent than subtraction.
Although, the order can be changed using Parentheses ().
example in (10 -4) * 2
values inside Parentheses will be evaluated first.
Associativity of Python operators
Associativity is the order in which an expression that has multiple operator of the same precedence is evaluated .
for example, multiplication ( * ) and floor division ( // ) have same precedence.
Almost all the operators have left-to-right associativity.
Note: operators precedence can be found online in tabular form in the Python documentation
