Data Types in Python

In Python, every value has a data type that determines its nature and the operations that can be performed on it. Python has several built-in data types, including:

• Integer (int): Represents whole numbers, both positive and negative.
• Float (float): Represents real numbers with decimal points.
• String (str): Represents sequences of characters.
• Boolean (bool): Represents either True or False.

Let's take a look at an example that demonstrates the use of the type() function to determine the data types of variables:

1# Python code to demonstrate
2# type() built-in function
3
4# initializing variables
5a = 5
6b = 2.7
7message = 'Hello, world!'
8
9# printing the types
10print(type(a))
11print(type(b))
12print(type(message))

The above code will output:

1<class 'int'>
2<class 'float'>
3<class 'str'>

This shows that a is of type int, b is of type float, and message is of type str.

Understanding the data types in Python is essential as it allows you to perform appropriate operations and manipulate data effectively.

# Python code to demonstrate

# type() built-in function

​

# initializing variables

a = 5

b = 2.7

message = 'Hello, world!'

​

# printing the types

print(type(a))  # <class 'int'>

print(type(b))  # <class 'float'>

print(type(message))  # <class 'str'>
