Python Coding challenge - Day 451| What is the output of the following Python Code?


 Code Explanation:

1. Defining the Class
class Magic:
What it does: Starts a class definition named Magic.

2. Overriding __bool__

    def __bool__(self): return False
What it does: Overrides the __bool__() special method.

Purpose: This method defines the "truthiness" of an instance when passed to bool() or used in conditions like if m.

Return value: Always returns False, so the object will be treated as False in boolean contexts.

3. Overriding __len__
    def __len__(self): return 1
What it does: Overrides the __len__() special method.

Purpose: Defines what should be returned when len(m) is called.

Return value: Always returns 1.
 
4. Creating an Instance
m = Magic()
What it does: Creates an instance of the Magic class and stores it in the variable m.

5. Printing the Results
print(bool(m), len(m))
bool(m):
Since __bool__ is defined and returns False, this evaluates to False.
len(m):
This calls the __len__() method, which returns 1.


Final Output:

False 1
