Pick Apart Your User's Input (Solution)

00:00 Here we are. I created a new file called first_letter.py and just took a quick note of the task, which is to return the uppercased first letter entered by the user.

00:11 That means I’m going to have to collect the user input again. I will again assign that to a variable called user_input

00:18 and then just call the input() function with a prompt, "Tell me your password: ".

00:28 Add a space to make it display nicer here.

00:33 That should collect the user input, so whatever the input is going to be saved to the variable user_input. And then I need to get the first letter of that.

00:42 I’ll be explicit and assign the first letter to a new variable that I’ll call here first_letter, and then I will use user_input, which will hold the string that the user input and then use indexing to get the first character by using square brackets and putting in 0.

01:03 So I want the character at position zero. That’ll be the first letter. And then the task is to display that back with a short message. So again, I will use the print()

01:17 function and the string in here that says "The first letter you entered was", put a colon and a space, and then we’ll concatenate this with my variable, the first_letter variable, but it will also uppercase it, .upper().

01:39 So I could also uppercase it here. I could say user_input[0].upper(). That would work as well, but that’s a bit less readable, especially because for now I just called the variable first_letter.

01:53 I could change it to calling it first_letter_uppercase and then add the .upper() right after getting the first letter using the index.

02:06 But anyway, so there are always different types of solutions. If you solved it in a different way, that’s fine as well. I’m going to stick with this, where I uppercase the first letter before printing it out.

02:19 Okay, let’s see whether it works. I’m going to press F5 to run the script. Tell me your password: and I will say No, and The first letter you entered was: N.

02:30 Let’s try it again with a different input. Tell me your password: PaSSworD, and it tells me The first letter you entered was: P.

02:42 Let’s see whether the uppercasing works. I actually haven’t tested it because both of the inputs already had an uppercase. I will run it yet another time.

02:51 Tell me your password: and I’ll start with lowercase pwd, and The first letter you entered was: P, so it uppercased it correctly.

03:00 Great. So this is a working solution, and I’m satisfied with it. Did you get something else? If you did, then post it down in the comments.
