# Python Data Types MCQ

Diving into the world of Python programming is an exciting journey, and understanding the basic data types is a important step. Python offers a diverse range of built-in data types, from simple integers and floats to complex lists and dictionaries.

In this blog post, we've prepared a set of 15 Multiple Choice Questions (MCQs) specifically designed for beginners to evaluate their understanding of Python's data types. Accompanying each question is a detailed explanation to enhance your learning experience. Let's get started!

## 1. What is the data type of: 5?

a) Float
b) String
c) Integer
d) Complex

c) Integer

### Explanation:

The value 5 without a decimal point is an integer.

## 2. Which of the following is a mutable data type?

a) Tuple
b) String
c) List
d) Int

c) List

### Explanation:

Lists in Python can be altered after their creation, hence they are mutable. Other options are immutable.

## 3. Which data type is ordered and changeable, and allows duplicate members?

a) Set
b) Tuple
c) Dictionary
d) List

d) List

### Explanation:

A list is ordered, can be altered, and can have duplicate members.

## 4. What does the following code produce: type(5.0)?

a) int
b) float
c) str
d) complex

b) float

### Explanation:

5.0 is a floating-point number, so the type function will return float.

## 5. Which of the following can't be a dictionary key?

a) Integer
b) Tuple
c) List
d) String

c) List

### Explanation:

Dictionary keys must be immutable, and since lists are mutable, they can't be used as dictionary keys.

## 6. Which data type is unordered and unindexed?

a) Set
b) List
c) Tuple
d) Dictionary

a) Set

### Explanation:

Sets in Python are both unordered and unindexed.

## 7. Which of these is used to represent a sequences of characters?

a) List
b) Tuple
c) String
d) Set

c) String

### Explanation:

Strings are sequences of characters in Python.

## 8. Which data type cannot contain duplicate values?

a) List
b) Tuple
c) Set
d) Dictionary

c) Set

### Explanation:

Sets are unindexed collections of unique elements. They don't allow duplicates.

## 9. What is the output of type((1,2))?

a) List
b) Set
c) Tuple
d) Dictionary

c) Tuple

### Explanation:

The values 1 and 2 enclosed in parentheses form a tuple.

## 10. Which of the following data types does not allow slicing?

a) String
b) List
c) Set
d) Tuple

c) Set

### Explanation:

Sets are unordered and unindexed, so slicing operations are not supported.

## 11. Which data type is immutable?

a) List
b) Dictionary
c) String
d) Set

c) String

### Explanation:

Strings in Python are immutable, meaning their values can't be altered after they're created.

## 12. How can you represent complex numbers in Python?

a) a+b
b) a_b
c) a+bj
d) a.b

c) a+bj

### Explanation:

In Python, complex numbers are represented as a+bj, where a and b are floats.

## 13. Which of the following is not a Python data type?

a) List
b) Class
c) Tuple
d) Dictionary

b) Class

### Explanation:

While classes are used to define new types in Python, they themselves aren't a data type.

## 14. Which data type is mutable but ordered?

a) Tuple
b) Set
c) List
d) String

c) List

### Explanation:

Lists are ordered collections of elements and they can be modified after their creation.

a) List
b) Tuple
c) Set
d) Dictionary
