Python Coding Challenge - Question with Answer (ID -190726)

 

Explanation:

Line 1: print(...)

print() is a built-in Python function.

It is used to display the output on the screen.

Whatever is inside the parentheses () is evaluated first, and then the result is printed.

Line 2: {1, 2, 3}

{1, 2, 3} is a set.

A set is an unordered collection of unique elements.

Elements in this set are:

1

2

3

Line 3: {2, 3, 4}

This is another set.

It contains:

2

3

4

Line 4: & (Intersection Operator)

The & operator is called the intersection operator for sets.

It returns only the elements that are common to both sets.

First Set

{1, 2, 3}

Second Set

{2, 3, 4}

Common Elements

2

3

So,

{1, 2, 3} & {2, 3, 4}

becomes

{2, 3}

Line 5: print({2, 3})

The print() function displays the result:

{2, 3}

Output

{2, 3}
