Python Coding challenge - Day 238 | What is the output of the following Python Code?

 

In Python, dictionaries are compared based on their keys and corresponding values. When you use the != operator to compare two dictionaries, it checks if there is any difference between them.

Here’s the explanation for the given code:

dict1 = {"a": 1, "b": 2}

dict2 = {"a": 1, "b": 3}

print(dict1 != dict2)

Dictionary Creation:

dict1 is created with keys "a" and "b" having values 1 and 2, respectively.

dict2 is created with keys "a" and "b" having values 1 and 3, respectively.

Comparison:

The comparison dict1 != dict2 checks if dict1 is not equal to dict2.

Python compares each key-value pair in dict1 with the corresponding key-value pair in dict2.

Key-Value Comparison:

Both dictionaries have the same keys: "a" and "b".

For key "a", both dictionaries have the value 1. So, these are equal.

For key "b", dict1 has the value 2 and dict2 has the value 3. These are not equal.

Since there is at least one key-value pair that differs ("b": 2 in dict1 vs. "b": 3 in dict2), the dictionaries are considered not equal.

Result:

The expression dict1 != dict2 evaluates to True.

Therefore, the output of print(dict1 != dict2) will be True, indicating that dict1 is not equal to dict2.
