Types of Variables in Python<\/strong><\/h2>\n\n\n\n

Variable Types <\/strong>in Python are just reserved memory spaces for storing values. This means that when you create a variable, you reserve memory space.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Python is entirely object-oriented and is not “statically typed.” You do not need to declare variables or declare their type before utilizing them.<\/p>\n\n\n\n

<\/p>\n\n\n\n

These are some of the common types of variables in Python.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Variable Type<\/th>Description<\/th>Example<\/th><\/tr><\/thead>
Integer<\/td>Stores whole numbers without decimal points<\/td>age = 30<\/td><\/tr>
Float<\/td>Stores decimal numbers<\/td>pi = 3.14<\/td><\/tr>
String<\/td>Stores sequences of characters<\/td>name = “Mary”<\/td><\/tr>
Boolean<\/td>Stores either True or False<\/td>is_valid = True<\/td><\/tr>
List<\/a><\/td>Stores an ordered collection of items<\/td>numbers = [1, 2, 3, 4]<\/td><\/tr>
Tuple<\/a><\/td>Stores an ordered collection of items (immutable)<\/td>point = (5, 10)<\/td><\/tr>
Dictionary<\/a><\/td>Stores key-value pairs<\/td>person = {“name”: “Mary”, “age”: 30}<\/td><\/tr>
Set<\/a><\/td>Stores an unordered collection of unique items<\/td>unique_numbers = {1, 2, 3, 4}<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Assigning Values to Variables<\/strong><\/h2>\n\n\n\n

Assigning values to variables in Python<\/strong> is a fundamental concept. It allows you to store and manipulate data within your code. <\/p>\n\n\n\n

<\/p>\n\n\n\n

To assign a value to a variable, you can use the assignment operator “=”.<\/p>\n\n\n\n

<\/p>\n\n\n\n

The name of the variable is the operand to the left of the = operator, and the value stored in the variable is the operand to the right of the = operator. <\/p>\n\n\n\n

<\/p>\n\n\n\n

For instance:<\/strong><\/p>\n\n\n\n

#!\/usr\/bin\/python\n\nnumber = 100          # An integer assignment\nscore   = 98.5          # A floating point\nname    = \"Prince\"          # A string\n\nprint counter\nprint miles\nprint name<\/strong><\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
In this case, the values for the counter, miles,<\/em><\/strong> and name<\/em><\/strong> variables are 100, 98.5, and “Prince”<\/em><\/strong>, respectively. <\/p>\n\n\n\n
<\/p>\n\n\n\n
This causes the following to happen:<\/p>\n\n\n\n
100\n98.5\nPrince<\/strong><\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
Multiple Assignment<\/strong><\/h2>\n\n\n\n
In Python, you can assign values to multiple variables in a single line using multiple assignments.<\/p>\n\n\n\n
<\/p>\n\n\n\n
This allows concise assignment to multiple variables simultaneously.<\/p>\n\n\n\n
<\/p>\n\n\n\n
For instance:<\/strong><\/p>\n\n\n\n
# Multiple assignment\nx = y = z = 1<\/strong><\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
In this case, we’re creating an integer object of type 1 and setting all three variables to the same address in memory.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Multi-object assignments to multiple variables are also supported.<\/p>\n\n\n\n
<\/p>\n\n\n\n
For example:<\/strong><\/p>\n\n\n\n
# Multiple assignment to multiple variables\nx,y,z = 1,2,\"prince\"<\/strong><\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
Here, the variables x<\/strong><\/em> and y<\/strong><\/em> are given the values 1<\/strong> and 2<\/strong>, respectively, and the variable z<\/strong><\/em> is given the value “prince<\/em><\/strong>” from a string object.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Different Types of Variables in Python<\/strong><\/strong><\/h2>\n\n\n\n
In Python, there are different types of variables that you can use to store and manipulate data.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Here are some common types of variables:<\/p>\n\n\n\n
1. Python Numbers<\/strong><\/h3>\n\n\n\n
In Python, the Numbers <\/a>variable type or data type holds values that number. You make a number object when you give it a value.<\/p>\n\n\n\n
<\/p>\n\n\n\n
For example:<\/strong><\/p>\n\n\n\n
var1 = 1\nvar2 = 10<\/strong><\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
You can also use the del<\/em><\/strong> statement to remove the reference to a number object.<\/p>\n\n\n\n
The del<\/em><\/strong> statement’s syntax is:<\/p>\n\n\n\n
#del statement\ndel var1[,var2[,var3[....,varN]]]]<\/strong><\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
The del<\/em><\/strong> statement lets you delete a single object or a group of objects.<\/p>\n\n\n\n
For instance:<\/p>\n\n\n\n
del var\ndel var_a, var_b<\/strong><\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
Python can work with four different kinds of numbers.<\/p>\n\n\n\n
