Answer 1

This should work:

myFile = open("Books.txt", "r")
myFile = myFile.read()
lines = myFile.split("\n")
for txt in lines:

        print(txt)
        AddPubDate = ":",input("Enter the publication date for book above")
        NewLine = str(txt) + str(AddPubDate)
        with open("books2.txt", "a") as f:
            f.write(NewLine+"\n")
            print(NewLine)
myFile.close()
print("Process complete")
