Variable In Python #python смотреть онлайн

In Python, a variable is a name that represents a value. It is a container that can hold a data value and can be used throughout the code. Variables can store different types of values, such as numbers, strings, lists, and objects.


To create a variable in Python, you simply need to assign a value to a name using the assignment operator (=). For example:


```
age = 25
name = "John"
```


In this example, `age` is a variable that holds the value `25`, and `name` is a variable that holds the string `"John"`. Python automatically detects the type of the value assigned to the variable and assigns the appropriate data type to the variable.


You can also change the value of a variable by reassigning it to a new value. For example:


```
age = 25
age = 30
```


In this example, the variable `age` is first assigned the value `25`, and then it is reassigned the value `30`.


It is important to note that Python is a dynamically-typed language, which means that you do not need to declare the data type of a variable before using it. The data type is automatically assigned based on the value assigned to the variable.
