Firstly we explain the variable and the declaration rule for the variable and further separating the valid and invalid variables.
- Whenever a user is given a question, variables are data values that can vary. for example age, CSL, etc.
- It may alter and during the execution of the program.
- It's a storage space for memories.
- It has a name that corresponds to the location.
- Data is stored in the memory location.
The rule for variable declaration:
- The names of your variables should be based on the phrases used in the subject area, and they should reflect the variable's function.
- By removing spaces between the words, you can make variable names. Each word in the name should be capitalized, including prepositions and pronouns that are one letter long.
- An underscore should never be used to start a variable name.
- Single-character variable names should be avoided. For loop counters, only short variable names are permitted.
- After the state that equals the "true" value, name variables that describe binary states ("true" or "false").
The valid variable is:
CSL, Age,CLS,SEE,Stop5for,Give, $shopping, and United.
The invalid variable is:
Mark-sheet, Tel $, Simple Interest, and 545Newton.

Answer:
Analog computers only work with continuous numerical data in analog quantities, digital computers can process both non-numerical and numerical data and a hybrid computer is a combination of both analog and digital. A hybrid computer has the accuracy of a digital computer paired with speed of an analog one.
The function use to get the number of element in a dictionary is len.
<h3>What is a dictionary?</h3>
Dictionaries are used to store data values in key-value pairs. Dictionary are ordered.
Dictionary in python are express as follows:
my_dict = {"name": "Michael", "age": 28, "school": "Oxford"}
Therefore, the length of the element of the dictionary can be gotten using the len() function.
Hence,
print(len(my_dict)) will give you the length of the element.

Answer:
The TAB key
Explanation:
Sam would use the TAB key, located on the left side of the keyboard, to move around his document to add stops and format its information properly.
Pressing the TAB key will introduce a tab code in his document, which is like moving ahead by a certain number of spaces (5,6, 10 spaces for example, depending on the configuration of the document), but without using spaces, using a tab which is a much better option to position, align things up.
