How to resolve a symlink to its real path in Python with pathlib

Use Path.resolve() to turn a symlink path into its absolute target path, handling relative symlinks and eliminating symbolic links.

pathlib symlink filesystem
Python 
from pathlib import Path

def resolve_symlink(path):
    p = Path(path)
    return str(p.resolve())

if __name__ == "__main__":
    # Create a symlink to demonstrate the resolution
    target = Path("/tmp/real_target.txt")
    target.write_text("hello")
    link = Path("/tmp/my_link.txt")
    try:
        link.symlink…

How to Call a Parent Class __init__ with super() in Python

Shows how to chain __init__ calls through a class hierarchy using super(), so each class sets its own attributes while reusing the parent's initialization logic.

oop inheritance super
Python 
class Animal:
    def __init__(self, name, species):
        self.name = name
        self.species = species
        print(f"Animal init: {self.name}, {self.species}")

class Mammal(Animal):
    def __init__(self, name, species, fur_color):
        super().__init__(name, species)
        self.fur_color = fur_color

Understanding Multiple Inheritance Method Resolution Order in Python

This code demonstrates how Python's MRO determines which greet method is called in a diamond inheritance scenario, and prints the full MRO for class D.

multiple inheritance mro inheritance
Python 
class A:
    def greet(self):
        return "Hello from A"

class B(A):
    def greet(self):
        return "Hello from B"

class C(A):
    def greet(self):
        return "Hello from C"

class D(B, C):
    pass


if __name__ == "__main__":
    d = D()
    print(d.greet())
    print(D.__mro__)
