Quiz - 1 (Introduction to Python)

Q1: What will be the output of the following code?

print('Career')
print('Labs')

CareerLabs Career Labs Career Labs(in next line) "Career""Labs"

Answer: Career Labs(in next line)
Explanation: "Career" and "Labs" are printed in separate lines because by default print() ends with a new line.

Q2: What will be the output of the following code?

print('Hello')
print('World')

Hello World HelloWorld Hello (newline) World 'Hello' 'World'

Answer: Hello (newline) World
Explanation: By default, print() adds a new line after each call.

Q3: What will be the output of the code?

a = 10
b = 20
multiple = a * b
print('multiple')

20 200 multiple None

Answer: multiple
Explanation: Anything in quotes is treated as a string, so it prints 'multiple'.

Q4: What will be the output if inputs are "abc" and "def"?

a = int(input())
b = int(input())
c = a + b
print('c')

abcdef abc+def Value Error None

Answer: Value Error
Explanation: int() expects integers. Strings give ValueError.

Q5: What will be the output if inputs are 40 and 57 (typecast int)?

a = int(input())
b = int(input())
c = a + b
print('c')

97 40 + 57 4057 None

Answer: 97
Explanation: Integers are added numerically.

Q6: What will be the output if inputs are 40 and 57 (without typecast)?

a = input()
b = input()
c = a + b
print('c')

97 40 + 57 4057 None

Answer: 4057
Explanation: input() returns strings. Concatenation gives '4057'.

Q7: What is the output of print(17/10)?

1.7 1 2 None

Answer: 1.7
Explanation: '/' performs floating-point division.

Q8: What is the output of print(17//10)?

1.7 1 2 None

Answer: 1
Explanation: '//' is floor division.

Q9: Will id1 and id2 have the same value?

a = 10
id1 = id(a)
b = a + 2 - 2
id2 = id(b)

Yes No Can't say None

Answer: Yes
Explanation: Integers with the same value share the same memory id in Python.

Q10: What is the type of x after execution?

x = 'abcd'
x = 10

str int float complex

Answer: int
Explanation: Variables take the type of the last assigned value.
