Challanges Of Python Identify Operators

 

What is the result of this code?

x = {1: "a"}
y = x
print(x is y)

Explanation:

1. What the is Operator Does

The is operator checks whether two variables refer to the same memory location, not just if they have the same value.

2. Code Breakdown

• x = {1: "a"}:
  • A dictionary is created with one key-value pair (1: "a").
  • The variable x points to the memory location of this dictionary.
• y = x:
  • The variable y is assigned the same reference as x.
  • Now, both x and y point to the same memory location and represent the same dictionary.

• print(x is y):

  • Since x and y point to the same dictionary object in memory, x is y evaluates to True.

3. Why This Happens

In Python, assigning one variable to another (e.g., y = x) doesn't create a new object. Instead, it creates a new reference to the same object in memory.

The output of this code will be:

True
