Data Types in Python – Part 1

Data types tell Python what kind of data a variable contains. Python has different data types for storing different kinds of values.

In this part, we will learn about Numbers, Strings, and Boolean.

1. Integer (int)

An integer is used to store whole numbers.

age = 21
print(age)

Output:

21

2. Float (float)

A float is used to store numbers with decimal values.

price = 99.50
print(price)

Output:

99.5

3. Complex (complex)

Complex numbers contain a real part and an imaginary part.

number = 2 + 3j
print(number)

Output:

(2+3j)

4. String (str)

A string is used to store text.

name = "Vishnu"
print(name)

Output:

Vishnu

Strings can be written using single or double quotes.

5. Boolean (bool)

Boolean is used when a value can be True or False.

is_logged_in = True

print(is_logged_in)

Output:

True

Checking the Data Type

We can use the type() function to check the type of a value.

age = 21
name = "Vishnu"

print(type(age))
print(type(name))

Output:

<class 'int'>
<class 'str'>
