Variables in Python

In Python, a variable is a named location in memory that stores a value. When you create a variable, you give it a name and specify the value you want it to store. You can then use the variable in your program to represent the value stored in it. For example:

>>> x = 10
>>> y = "hello"
>>> z = 3.14

Here, x is a variable that stores the integer value 10, y is a variable that stores the string value, and z is a variable that stores the float value 3.14. You can use variables in your program to make it easier to read and write. For example, instead of writing 10 every time you want to refer to the number 10, you can use the variable x to represent it. This can make your code more readable and easier to understand.

It’s important to choose descriptive and meaningful names for your variables. This makes it easier for others (and yourself) to understand what the variables represent in your code. It’s also a good idea to follow the naming conventions in Python, which means using lowercase letters and underscores for variable names, and avoiding using reserved keywords.
