What are legal variable names?
Variable names are identifiers that are used to refer to specific memory locations in a computer program. They are used to store data and to manipulate it. Variable names can be any combination of letters, numbers, and underscores, but they cannot start with a number. The first letter must be a letter.
Some languages, such as C++, allow you to use keywords as variable names. These are the words that are used to define the language itself. For example, in C++, the keyword int is used to declare a variable that will store an integer value. You cannot use this keyword as a variable name in your program.
Variable names are not case-sensitive, so you can use uppercase or lowercase letters. However, it is a good practice to use uppercase letters for variable names because they are easier to read.
The following are some examples of valid variable names:
age
total_bill
number_of_guests
last_name
The following are not valid variable names:
1age
2total_bill
3number_of_guests
4last_name

Python is a widely used high-level interpreted language. It has a design philosophy entitled “There’s only one way to do it, and that’s why it works.” It can be read and written by people of all levels of programming experience. The language has gained in popularity due to its clear syntax and code readability.

What are the 4 variable types in Python?
Python has 4 main variable types:
1. Numbers
2. Strings
3. Lists
4. Dictionaries
Numbers can be either integers (e.g. 1, 2, 3) or floats (e.g. 1.5, -3.14).
Strings are sequences of characters (e.g. “Hello, world!”).
Lists are sequences of other objects, where each object is identified by an index (e.g. [1, 2, 3, “apple”]).
Dictionaries are also sequences of objects, but the objects are identified by their key rather than their index (e.g. {1: “one”, 2: “two”, 3: “three”}).
What are 3 types of variables?
There are three main types of variables: scalar, vector, and matrix.
A scalar variable is a single value, such as the number 5.
A vector variable is a list of values, such as the list of numbers [1, 2, 3, 4].
A matrix variable is a grid of values, such as the grid of numbers [[1, 2, 3], [4, 5, 6]].
