I don't understand this code

[Artinflamepurity]

class SpecialString: def init(self, cont): self.cont = cont

def __truediv__(self, other):
	line = "=" * len(other.cont)
	return "\n".join([self.cont, line, other.cont])

spam = SpecialString("spam") hello = SpecialString("Hello world!") print(spam / hello)

Fix: #42

In Python, truediv is used to overload the division operator (/), so when you use / between two SpecialString objects, this method is called instead of performing regular division.

What does it do?: 1. self.cont: The string inside the first object (on the left of /). 2. other.cont: The string inside the second object (on the right of /). 3. line = "=" * len(other.cont) creates a line of equal signs (=) that has the same length as other.cont (the string in the second object). 4. "\n".join([self.cont, line, other.cont]): This joins three strings: -> self.cont (the first string), -> line (a line of equal signs), -> other.cont (the second string), and puts a newline (\n) between them.

You create two objects: -> spam = SpecialString("spam"): This stores the string "spam" in the cont attribute of the spam object. -> hello = SpecialString("Hello world!"): This stores the string "Hello world!" in the cont attribute of the hello object.

When you use spam / hello, this calls the truediv method and does the following: -> It takes spam.cont, which is "spam". -> It calculates the length of hello.cont, which is "Hello world!", and creates a line of equal signs with that length. Since "Hello world!" is 12 characters long, line becomes "============". -> It joins spam.cont ("spam"), the line of equal signs ("============"), and hello.cont ("Hello world!"), separating them with newlines.

print(spam/Hello) is basically print(spam.truediv(hello))

Final Output: spam

Hello world!

The truediv method is a magic method (also known as a dunder method, short for "double underscore"). Magic methods in Python are special methods that allow you to define the behavior of built-in operators (like +, -, *, /, etc.) for instances of your custom classes.

print(spam / hello) so here when we writing above code we are overriding the usual behavior of '/' and calling this magic method.

This method is triggered when you use the / operator with instances of the SpecialString class. When spam / hello is executed, the truediv method gets called with self being spam and other being hello. It creates a line of = characters whose length is equal to the length of other.cont (which is the string in the hello object). Then, it returns a string with the following structure:

Spam ======== Hello World

Basically in one shot you are passing two object one by self and other by parameter and then doing some concatenation and returning the result.
