Here, fname is ‘Lucifer’ and lname is ‘Satan’. You can assign different values to multiple variables in a statement. You can also use foreign characters in variable names. This gives us a Synta圎rror as we cannot assign to a literal. The variable name has the value ‘TechVidvan’, but later, it has the value 8. This is how we assign a variable: name=‘TechVidvan’ Like we said, we do not declare variables, we assign them.

According to PEP8, you should name long variables names like this- long_variable_name with underscores.

The variable ‘name’ is different than the variable ‘Name’.

Python variable names are case-sensitive.

Variable names can be of any length but you should try to not exceed 79 characters.

In this list, all words except True, False, and None are in lowercase.

You cannot use a word from this list as a name for your variable or function. They define the syntax and structure of Python.

Let’s take some examples of valid variable names: You can also not use whitespace or the signs + and – in a name. It cannot be a reserved keyword for Python.Ī variable’s name can be made of letters, digits, and underscores but you cannot begin it with an underscore or a digit.It cannot have whitespace and signs like + and -, !, $, #, %.It cannot begin with an underscore (_) or a digit.Variables can have letters (A-Z and a-z), digits(0-9) and underscores.A variable name is called an identifier and has to follow some rules: One variable can hold different types of objects. We do not declare a variable, we directly assign to it. This is decided by the interpreter at runtime. When assigning to a variable, we do not need to declare the data type of the values it will hold. We do not declare the type of variable – name is ‘TechVidvan’. We can refer to this now with the name ‘name’. Python variables are containers for storing data values.
