Variables and Types

To create a variable in Python, you simply need to choose a name and assign it a value using the = operator. For example, to create a variable called x and assign it the value 5, you would write:


Python has several different data types, including:

Integers: whole numbers, like 1, 2, and 3
Floating-point numbers: decimal numbers, like 3.14 and 2.71828
Booleans: True or False values that represent truth or falsehood
Strings: sequences of characters, like "hello" and "world"

When you assign a value to a variable, Python will automatically determine the appropriate data type based on the value you provide. For example, if you assign the value 5 to a variable, Python will create an integer variable. If you assign the value 3.14 to a variable, Python will create a floating-point variable.

You can check the type of a variable using the type() function. For example, to check the type of the x variable we created earlier, you would write:


This would output <class 'int'>, indicating that x is an integer variable.
