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))
Thetruediv 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.
