Operator Precedence in Python
In this article, we will learn about precedence and different other concerning concepts. So, let’s not wait and begin. Before talking about operator precedence, first, let us know about expressions. In Python, expression can be defined as a valid combination of variables, constants, operators, and function calls.

Priority (precedence) of the logical operators (order of operations ...
First, try 0 and 0 or 1 in python console. If or binds first, then we would expect 0 as output. In my console, 1 is the output. It means and either binds first or equal to or (maybe expressions are evaluated from left to right). Then try 1 or 0 and 0.

Precedence and Associativity of Operators in Python
In Python, operators have different levels of precedence, which determine the order in which they are evaluated. When multiple operators are present in an expression, the ones with higher precedence are evaluated first. In the case of operators with the same precedence, their associativity comes into play, determining the order of evaluation.

Python Booleans: Use Truth Values in Your Code – Real Python
Because True is equal to 1 and False is equal to 0, adding Booleans together is a quick way to count the number of True values. This can come in handy when you need to count the number of items that satisfy a condition.

Mastering Python Order of Operations
In mathematics, we often represent the order of operations by the acronym PEMDAS. The order of operations is similar in Python, but with a few differences: Let’s take a look at some examples to see how this works in practice. The first step in evaluating an expression in Python is to evaluate any expressions inside parentheses. For example:

What is the order of what Python sees here? Another is: returns 1. From what I gathered from the first example, I thought Python would evaluate from left to right, so '1 or False' would return 1, then '1 and 2' would return 2, then '2 or 2' would return the first 2, then '2 and 0' would return 0, then '0 or 0' would return the second 0.

However, to clarify operation order or when mixing different types of operators, using parentheses can be helpful. See the official documentation below for a summary of operator precedence in Python. 6. Expressions - Operator precedence — Python 3.12.1 documentation.

Precedence and Associativity of Operators in Python - Programiz
To evaluate these types of expressions there is a rule of precedence in Python. It guides the order in which these operations are carried out. For example, multiplication has higher precedence than subtraction. But we can change this order using parentheses () as it has higher precedence than multiplication.

8.5. Precedence of Operators — Foundations of Python Programming
Arithmetic operators take precedence over logical operators. Python will always evaluate the arithmetic operators first (** is highest, then multiplication/division, then addition/subtraction). Next comes the relational operators. Finally, the logical operators are done last.
