Explain the concept of variables in Python and provide examples of different variable types.

In Python, variables are used to store and manipulate data. They act as containers that hold a value, which can be of different types such as numbers, strings, lists, or objects. Variables play a crucial role in programming as they allow data to be stored, retrieved, and modified during the execution of a program. Here is an in-depth explanation of the concept of variables in Python along with examples of different variable types: 1. Numeric Variables: Numeric variables are used to store numerical values such as integers, floating-point numbers, or complex numbers. Examples include: ``` python`age = 25 pi = 3.14159 complex_num = 2 + 3j` ``` 2. String Variables: String variables are used to store sequences of characters. They are enclosed in either single quotes ('') or double quotes (""). Examples include: ....
