In Python, variables are used to store data values. These data values can be of various types, such as numbers, strings, lists, or more complex objects. Defining variables in Python is a fundamental aspect of programming, and it follows specific rules and conventions. Here's a comprehensive explanation of how to define variables and the rules for naming them in Python:
Defining Variables:
In Python, you can define a variable by assigning a value to it using the assignment operator `=`. The basic syntax is:
```python
variable_name = value
```
- `variable_name` is the name you choose for the variable.
- `value` is the data you want to store in the variable.
For example:
```python
name = "John"
age = 30
```
In this code, two variables, `name` and `age`, are defined. `name` stores a string value "John," and `age` stores an integer value 30.
