Answer:

Written in Python

filenm = input("File name: ")

myfile = open(filenm+".txt")

for i in range(10):

     line = myfile.readline()

     print(line)

print("End of file")

Explanation:

This line prompts user for file name

filenm = input("File name: ")

This line creates an instance of the file

myfile = open(filenm+".txt")

This line iterates through the 10 lines

for i in range(10):

This line reads the line

     line = myfile.readline()

This line prints each line

     print(line)

This line prints a message indicating that all possible lines have been printed

print("End of file")

On the Direct Marketing worksheet, create appropriate range names for Design Fee (cell B8), Cost Per Ad (cell B9), Total Clicks
Inessa [10]

Answer:

See explanation below

Explanation:

Named ranges are a very important tool in Microsoft Excel. It is used in assigning a name to a particular number of cells. It is great for automation and makes formula much easy to understand and use.

One way to create named ranges is theory the Name Box.

To create named ranges in the design marketing sheet we do this;

1) We click on cell B8 and then navigate to the name box at the top right corner of the sheet just above the column A.

•The name box is where the cell address of any cell that is active is displayed.

•You would see that “B8” is displayed on the name box.

• Double click on the name box and type in the appropriate name, in this case - Design_Fee.

• Press enter and you have your named range.

You do the same for the other named ranges.

Note that: Named ranges must contain letters, numbers or underscore.
