Python Coding challenge - Day 142 | What is the output of the following Python Code?

 


In Python, the expressions within curly braces {} are evaluated as set literals. However, the expressions 1 and 2 and 1 or 3 are not directly used to create sets. Instead, these expressions are evaluated as boolean logic expressions and the final results are used to create sets.

Let's break down the expressions:

s1 = {1 and 2}

s2 = {1 or 3}

result = s1 ^ s2

print(result)

1 and 2: This expression evaluates to 2 because and returns the last truthy value (2 is the last truthy value in the expression).

1 or 3: This expression evaluates to 1 because or returns the first truthy value (1 is the first truthy value in the expression).

Therefore, your sets become:

s1 = {2}

s2 = {1}

result = s1 ^ s2

print(result)

Output:

{1, 2}

In this example, the ^ (symmetric difference) operator results in a set containing elements that are unique to each set ({1, 2}).
