What will be displayed by the following code?

```python
# Start of Code
def f(value, values):
v = 1
values[0] = 44
# End of function

t = 3
v = [1, 2, 3]
f(t, v)
print(t, v[0])
# End of Code
```

A. 1 44

B. 1 1

C. 3 44

D. 3 1

Answer :

The output of the code will be '3 44' because the function modifies the first element of the list to 44, but the integer variable t remains the same. the correct answer is C

The code snippet provided is an example of a function manipulation in Python. When f(t, v) is called, the function f receives t, which is the integer 3, and v, which is the list [1, 2, 3]. Inside the function, the first value of the list values is changed to 44. However, the variable t remains unchanged because integers are immutable in Python and are passed by value.

After the function call, when print(t, v[0]) is executed, t still holds the value 3, and v[0] is now 44 because lists are mutable and are passed by reference, allowing in-place modifications. Thus, the correct output as displayed by the code is:

C) 3 44
