Python MCQ Part – 2

1) Study the following program:

<br />
print(print(print(“javatpoint”)))<br />

What will be the output of this program?

javatpoint None None
None None javatpoint
None javatpoint None
Javatpoint

Answer: (a) javatpoint None None

Explanation: In this program, the inner print function will run first as compared to the outer print function. Therefore, the correct output of this program is “javatpoint None None”.

2) Study the following program:

<br />
print(True ** False / True)<br />

What will be the output of this program?

True ** False / True
1.0
1 ** 0 / 1
None of the these

Answer: (b) 1.0

Explanation: Binary values

True = 1

False = 0

(1 ** 0 / 1) = (1⁰/ 1) = 1.0

Therefore, option (b) is the correct output of this program.

3) Study the following program:

<br />
int1 = 10<br />
int2 = 6<br />
if int != int2:<br />
int2 = ++int2<br />
print(int1 – int2)<br />

What will be the output of this program?

2
4
6
None

Answer: (b) 4

Explanation: In the Python Programming Language, Increment and Decrement condition is not valid.

(y = ++y) = (y = y)

So, the output of this program is 4.

4) Study the following program:

<br />
int1 = 10<br />
int2 = 6<br />
if int != int2:<br />
int2 = ++int1<br />

What will be the output of this program?

2
4
0
No Output

Answer: (c) 0

Explanation: In the Python Programming Language, Increment and Decrement condition is not valid.

int1 = (10)

int2 = (6)

int2 = ++int1

int2 = 10

print(10 – 10)

So, the output of this program is the 0.

5) Study the following program:

<br />
print(6 + 5 – 4 * 3 / 2 % 1)<br />

What will be the output of this program?

Answer: (d) 11.0

9) Study the following program:

<br />
print(int(6 == 6.0) * 3 + 4 % 5)<br />

What will be the output of this program?

add = i + j<br />
print(add)<br />

What will be the output of this program?

5, 5
5
(2 , 3 , 5)
TypeError

Answer: (d) TypeError

Explanation: In this program, “i” is the integer value, and “j” is the tuple value. The integer and tuple values cannot be added in the python programming language. Therefore, this program will print the “Typeerror”.
