Python Variables and Data Types

Variables are used to store data, and Python supports several data types such as integers, floats, strings, and booleans. Understanding these is essential for any Python programmer.

1. Variables

Variables store data for later use:

name = "Vijay"
age = 20
is_student = True

Here, name is a string, age is an integer, and is_student is a boolean.

2. Common Data Types

• int: Whole numbers. Example: age = 20
• float: Decimal numbers. Example: height = 5.9
• str: Text. Example: name = "Vijay"
• bool: True or False. Example: is_student = True

3. Type Checking

You can check a variable’s type using type():

print(type(age))       # <class 'int'>
print(type(height))    # <class 'float'>
print(type(name))      # <class 'str'>
print(type(is_student))# <class 'bool'>

Conclusion

Understanding variables and data types is the foundation of Python programming. Next, you’ll learn how to make decisions using conditional statements.
