Answer:

Explanation:

The following program is written in Python. It asks the user for the file name (which needs to be in the same directory as the program) and reads the file. It then splits it by lines and saves it into an array. Then it loops through the array, printing each line with its corresponding line number.

file_name = input("File Name: ")

f = open(file_name, 'r')

lines = f.read().split('\n')

for line in lines:

   print(str(lines.index(line) + 1) + ': ' + line)

An electronic resume can carry so much data about the person, and it includes images also. Then the statement is true.

<h3>What is an electronic resume?</h3>

An electronic resume is termed as a resume that is read by a computer program that summarizes the information of each person.

The electronic resume has the data such as their parent name, education, skills, job experience, hobbies, languages, and so on.

Thus, the photo of the document about the project or internship that has been done in the past can be given on the electronic resume by uploading the certificate on the computer system along with the resume.

For example, in companies like Linkedin, and so on there are many companies that ask about the person before creating an account.

1. Separate valid and invalid variables:
DedPeter [7]

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.
