6. Expressions — Python 3.13.3 documentation
Thus, in an unparenthesized sequence of power and unary operators, the operators are evaluated from right to left (this does not constrain the evaluation order for the operands): -1**2 results in -1.

Python Booleans: Use Truth Values in Your Code – Real Python
Since Python Boolean values have only two possible options, True or False, it’s possible to specify the operators completely in terms of the results they assign to every possible input combination. These specifications are called truth tables since they’re displayed in a table.

What is the order of operations for logical operators? - Python FAQ ...
If you’re referring to the order of operations performed by @patrickd314, then only output is gained after evaluating through the input expressions.So for example, print (not False or True) Not False is evaluated first to become “not False” aka True. After that the or operator takes two True values to output a single outcome of True.
