🔥 Programming Questions with Answers & Explanations 👨‍💻🧠

Q1. What will be the output?

x = [1, 2, 3]

y = x

y.append(4)

print(x)

✅ Answer:

[1, 2, 3, 4]

💡 Explanation:
"y = x" does not create a new list.

Both "x" and "y" point to the same list in memory.

So when:

y.append(4)

the original list also gets updated.

Q2. What will be the output?

print(2**3**2)

Q3. What will be the output?

a = "5"
b = 2

print(a * b)

Q4. What will be the output?

def func(items=[]):
items.append(1)
return items

print(func())
print(func())

✅ Answer:

[1]
[1, 1]

💡 Explanation:
Default mutable arguments are created only once.

So the same list is reused every time the function is called.

First call:

[1]

Second call:

[1, 1]

Q5. What will be the output?

for i in range(3):
print(i)
else:
print("Done")

✅ Answer:

0
1
2
