Answer:

A variable in Python is defined using the assignment operator (=). The general syntax for defining a variable in Python is:

variable_name = value

Here's an example of defining a variable in Python:

x = 10

In this example, x is the name of the variable and 10 is the value assigned to it.

It's important to note that in Python, you don't have to declare the type of a variable. Python is a dynamically-typed language, which means that the type of a variable is determined by the value that is assigned to it. For example:

name = "John Doe" # name is a string
age = 30 # age is an integer

Once a variable is defined, you can use its value in your code by referencing its name. You can also reassign a different value to a variable by using the assignment operator again:

x = 20

In this example, the value of x has been changed from 10 to 20.
