Question

Write the output of the following :

>>> x = 8

>>> x = 5

>>> print (x + x)​

Answer 1

Given co‎de:

>>> x = 8

>>> x = 5

>>> print(x + x)

Output:

10

Explanation:

>>> x = 8

The value 8 is being stored to the variable 'x'.

>>> x = 5

'x' is later on being re-written with 5. So x's current value is 5 and not 8, and 'x' cannot hold two values [8 and 5].

>>> print(x + x)

Since x = 5, x + x = 5 + 5 = 10. Hence, 10 would be the result.

When the same variable is given a new value, the old value will be re-written/updated with the new one and will proceed onto the further steps with the new value.

Answer 2

$\: \: \: \red{ \boxed{\bold{Given \: Snippet : \orange{\begin{cases} \sf x=8 \\ \sf x=5 \\ \sf print(x+x) \end{cases}}}}}$

To find:

• Output

Step by step solution with Explaination:-

1. Intially x= 8
2. In line 2, x=5 so value of x is changed to 5
3. print(x+x)
4. This statement will print the sum of x
5. So current value of x is 5
6. x+x=5+5=10

Correct Output :

• 10
