2.2 Variables and Data Types
Python, a high-level programming language, is known for its use of variables. Variables allow programmers to store and manipulate data in a program. Every variable in Python is a specific location in the computer's memory that holds a value.
To assign values to variables, Python uses the equals sign (=), which is also known as the assignment operator. It is important to note that variables can hold different types of data, such as strings, integers, and floating-point numbers. By using variables, programmers can effectively write code that is easy to read, understand, and modify.
Example:
In the above example, we created three variables: x, y, and z. They hold an integer, a float, and a string respectively.
Python supports several data types out of the box, including:
2.2.1 Integers
These are whole numbers without a decimal point. They are commonly used in mathematics and computer programming to represent quantities that cannot be expressed in...
