A constant is a type of variable that holds values that cannot be changed. In reality, we rarely use constants in Python. Constants are usually declared and assigned to a different module/file. Example: Python 1 2 3 4 5 6 # Declare constants in a separate file called constant.py PI...

We want to know if we can read the file, so we use the constant os.R_OK to indicate that we want to know if the file is readable. If we can read the shadow file, we can eventually get the root password. This is what some penetration testers call “winning.” Otherwise, we will...

The type also determines whether the data value contained by the box can be changed (mutable) or is constant (immutable). There are two ways of specifying data values in Python: Literal, Variable Python variable names have some rules: They can contain only these characters: — Lowercase letter...
