Answer 11

What programming language do you want to use? You tagged a lot of them so do you mean you don’t care? And will this be connected to your email? Or will it be used for login like an app?

Answer 12

Is python alright though? I’m a bit of a novice in JavaScript. And I don’t know where in this app I’m supposed to write code either. I use my computer mostly. So I need to know where I write it first.

Answer 13

Will this email address be the only one? Or you be able to create a new one? Like if you don’t have an email another question will pop up saying please enter email address? I’m not sure if I can do that very well.

Answer 14

Yes.

It’ll be a little bit. I have to finish it up. And I might have to post it here because my email is not working right. LOL even though I am in a coding app right now

Answer 17

Does it matter what the numbers and letters are? Or can they just be random?

Answer 18

Try this,

email = input(‘Would you please-
-enter your email address: ‘)

if email == -
-‘[e-mail]’:

print(‘Welcome back!’)

else:

print(‘Sorry but that is incorrect’)

Answer 19

The dashes can be deleted, I just ran out of room and couldn’t fit them on the line. The spaces between each line can be deleted as well as I just put them there so you could tell the difference between the lines.
