Python Coding Challange - Question with Answer (01031025)

 

Step-by-step explanation

1) Initialization

data is a tuple with two elements:

data[0] → the list [10, 2]

data[1] → the tuple (3, 4)

2) Function call

result = tuple_sum(data) — inside the function t refers to the same tuple ([10, 2], (3, 4)).

3) Indexing details

t[0][0] → go to first element of t which is [10, 2], then its first element → 10.

t[1][1] → go to second element of t which is (3, 4), then its second element → 4.

4) Addition (digit-by-digit)

10 + 4

units: 0 + 4 = 4

tens: 1 + 0 = 1 → combine → 14

5) Return & print

Function returns 14.

print(result) outputs:

14

Key concept

Accessing nested elements uses multiple indices (t[0][0], t[1][1]).

Tuple immutability is not relevant here because we only read values (not modify). Tuples can hold mutable objects (like lists), but this example only accesses values and sums them.
