Python Coding Challenge - Question with Answer (ID -230226)

 

Explanation:

x = 10

Here, a variable named x is created and assigned the value 10.

At this moment, x points to the integer 10 in memory.

s = f"{x}"

This line creates an f-string.

The f before the string means formatted string

{x} is evaluated immediately

Since x is 10 right now, {x} becomes "10"

So:

s = "10"

Important: s stores a string, not a reference to x.

x = 20

Now the variable x is reassigned to a new value: 20.

This does not affect s, because s already contains the string "10".

print(s)

This prints the value stored in s.

Output:

10
