What are the rules of operation in Python?

The main rules of operations in Python include the following:

1. Priority: In Python, operators have different priorities, where operators with higher priorities are calculated before those with lower priorities. For example, multiplication and division have higher priority than addition and subtraction.
2. Associativity: When there are multiple operators with the same priority in an expression, Python will determine the order of calculation based on a certain associativity rule. For example, addition and subtraction are left-associative, meaning they are calculated from left to right; whereas the assignment operator is right-associative, meaning it is calculated from right to left.
3. Arithmetic operators: Python supports commonly used arithmetic operators such as addition (+), subtraction (-), multiplication (*), division (/), modulus (%) and so on.
4. Python supports logical operators such as “and”, “or”, and “not”.
5. Comparison operators: Python allows the use of comparison operators such as equal to (==), not equal to (!=), greater than (>), less than (<), and so on.
6. Python supports bitwise operators like bitwise AND (&), bitwise OR (|), bitwise NOT (~), etc.
7. Assignment operators: Python supports assignment operators such as equal (=), plus equal (+=), minus equal (-=), and so on.
8. Operator precedence: In Python, the operator precedence from highest to lowest is as follows: exponentiation (**), unary positive/negative (+, -), multiplication, division, modulus (*, /, %), addition, subtraction (+, -), comparison operators (==, !=, >, <, >=, <=), logical operators (and, or, not).

These are some basic arithmetic rules of Python that can assist us in various mathematical and logical operations.
