In programming, we work with data. When we write programs, we need an efficient way to store and manage this data — that's where variables come in. Variables are like labeled containers that hold different types of data depending on what we need to do.

There are various types of data such as:

• Integers (whole numbers, e.g., 10, 5)
• Floats (decimal numbers, e.g., 3.14, 99.99)
• Strings (text, e.g., "Hello World")
• Booleans (yes/no or true/false values, e.g., True, False)
• Lists (collections of items, e.g., [1, 2, 3])

Each type of data is used differently and has its own special behaviors. Here's what some of them can do:

• Numerical types (integers and floats) can be used in mathematical operations like addition (+), subtraction (-), multiplication (*), and division (/).
• Strings are used to represent text and can be combined (concatenated) using the + operator.
• Boolean values are used in logic to represent True or False and are often used in conditions or comparisons.
• Floats are ideal for representing values that require precision, such as currency or measurements.
• Lists are used to store multiple items in a single variable, and you can access them using their index.

You can get the data type of any object by using the type() function:

x = 5
print(type(x)) # outputs <class 'int'>
