Well Macy, I don't doubt that you know this and your just testing us but I think you should use all of these.
May I see the email? I can't help you until I know what it says
Yes but if the hard drive stops working you will lose your files so it's better to backup your files to a cloud like iCloud by Apple.
Go to settings, personalization, then background. Select the photo file you want to use. Should look like this.
f = int(input("Enter a number: "))
if(f%7==0):
print("It's divisible by 7.")
else:
if(f<7):
print("7")
else:
print(str(f-(f%7))+", "+str(f+(7-(f%7))))
