Topic :- Python (Basic To Advance Interview Question)

✅Correct Answer: A) 6

📘Explanation:

range(4) generates [0, 1, 2, 3].

The list comprehension [i for i in range(4)] creates a list of those values.

sum([0, 1, 2, 3]) = 6.

✅Correct Answer: B) False

📘Explanation:

An empty list [] is considered falsy in Python.

bool([]) converts the list to its Boolean value, which is False.

✅Correct Answer: B) a,b,c

📘Explanation:

The join() method concatenates elements of the list using the string before the dot as a separator.

So ",".join(["a", "b", "c"]) joins the list with commas: "a,b,c".

✅Correct Answer: C) <class 'dict'>

📘Explanation:

In Python, {} creates an empty dictionary, not a set.

An empty set must be created using set().

So type({}) returns <class 'dict'>.

✅Correct Answer: B) 4

📘Explanation:

The string "hello" has the characters: h, e, l, l, o.

set("hello") removes duplicates: {'h', 'e', 'l', 'o'}.

len(...) returns the number of unique characters, which is 4.

✅Correct Answer: A) [0, 0, 0].

📘Explanation:

[0]*3 means repeat the list [0] three times.

So it creates a new list with three zeros: [0, 0, 0].

✅Correct Answer: A) True

📘Explanation:

The all() function returns True only if all elements in the iterable are truthy.

True, 1, and "non-empty" are all considered truthy values in Python.

So all([True, 1, "non-empty"]) returns True.

✅Correct Answer: A) HelloHelloHello

📘Explanation:

In Python, multiplying a string by an integer repeats the string that many times. So "Hello" * 3 results in the string 'HelloHelloHello'. There's no space added automatically.
