• Static Methods

    The primary use of a static method in Python classes is to define a function that logically belongs to the class but doesn’t need access to the instance’s data (like self) or the class’s state (like cls). They are essentially regular functions that are grouped within a class namespace. Key Characteristics and Use Cases General…

  • Class Variables Andmethds

    Class Variables Class variables are variables that are shared by all instances of a class. They are defined directly within the class but outside of any method. Unlike instance variables, which are unique to each object, a single copy of a class variable is shared among all objects of that class. They are useful for…

  • Instance Variables,methods

    Instance Variables Instance variables are variables defined within a class but outside of any method. They are unique to each instance (object) of a class. This means that if you create multiple objects from the same class, each object will have its own separate copy of the instance variables. They are used to store the…

This is an effective way to extract the middle value from a semicolon-separated string. Title 1 to 25 chars The regular…

  • Negative lookbehind assertion

    A negative lookbehind assertion in Python’s re module is a zero-width assertion that checks if a pattern is not present immediately before the current position. It is written as (?<!…). It’s the opposite of a positive lookbehind and allows you to exclude matches based on what precedes them. Similar to the positive lookbehind, the pattern…

  • positive lookbehind assertion

    A positive lookbehind assertion in Python’s re module is a zero-width assertion that checks if the pattern that precedes it is present, without including that pattern in the overall match. It’s the opposite of a lookahead. It is written as (?<=…). The key constraint for lookbehind assertions in Python is that the pattern inside the…
