Answer:

In Python:

entry = input("Sentence: ")

while True:

if entry.count(",") == 0:

print("Error: No comma in string")

entry = input("Sentence: ")

elif entry.count(",") > 1:

print("Error: Too many comma in input")

entry = input("Sentence: ")

else:

ind = entry.index(',')+1

if entry[ind].isnumeric() == False:

print("Comma not followed by an integer")

entry = input("Sentence: ")

else:

break

print("Valid Input")

Explanation:

This prompts the user for a sentence

entry = input("Sentence: ")

The following loop is repeated until the user enters a valid entry

while True:

This is executed if the number of commas is 0

if entry.count(",") == 0:

print("Error: No comma in string")

entry = input("Sentence: ")

This is executed if the number of commas is more than 1

elif entry.count(",") > 1:

print("Error: Too many comma in input")

entry = input("Sentence: ")

This is executed if the number of commas is 1

else:

This calculates the next index after the comma

ind = entry.index(',')+1

This checks if the character after the comma is a number

if entry[ind].isnumeric() == False:

If it is not a number, the print statement is executed

print("Comma not followed by an integer")

entry = input("Sentence: ")

If otherwise, the loop is exited

else:

break

This prints valid input, when the user enters a valid string

print("Valid Input")

Note that: entry = input("Sentence: ") is used to get input

Julli [10]

A PDF must be put into an external program after being exported to be edited, you can't make direct changes to it. This eliminates answer choice A.

You can print documents with other extensions besides .pdf, such as those of Word documents and such, it doesn't have to be a .pdf. This eliminates answer choice B.

Since you can't directly edit a PDF, C is a possible answer.

Files don't have to be saved as a .pdf, especially just for the first time. Whenever you save a file, first time or not, you can save it as anything, and there's no reason to have to save it as a .pdf. This eliminates answer choice D.

So the answer is C. it contains material you don't want changed.

Hope this helps!
