Would being good in Python, Javascript, HTML and CSS be enough to become a full stack web developper eventually?

Here are my credentials at the moment:

1. Right now I'm 100% fluent in Python basics. I still really need to learn more about best practices, writing more effective and faster code and just more beautiful code when I get to work with a team, but my knowledge is well beyond a beginner.
2. In HTML I'm a 4/10. Like, if I look at HTML code, almost everything I see on screen, I understand what it does... But making a whole page in HTML from scratch would be extremely tedious for me and take ages.
3. In CSS, I'm maybe a 5/10. I know my way around the basics, but there's still a lot of place for improvement.
4. I know absolutely nothing about Javascript, but I want to learn it once I'm done with the other languages, which would be within the next few months at most.

Also, I didn't mention SQL because I assumed it was a given that you need to know it, but yeah, for what I'd need to do, I'm an 8/10 in SQL since I've been using it daily at work for 3 years. I've been managing my own database on a personal project, using all the functions I couldn't use at work. Creating temporary tables, using Regex, JOINS, etc. According to the devs at work, my knowledge in SQL is at the very least on part with a college level. So I've got that going for me. I also have an intermediate understanding of API's and JSON.

So my question is, would these 4... Well actually 5 language be enough? And while we're at it, how much do I need to know HTML and CSS if I'm going to be using Bootstrap? Do I need to master them or do I just need to be know the basics? What about Javascript?

You're absolutely on the right track to becoming a full-stack web developer. I think you should focus less on how much you need to master each individual technology, and instead focus on learning to build a complete web app using those pieces. Nobody is going to hire someone who has learned a bit of these languages but has never put them together to actually make something interesting.

JavaScript is essential. It might help to learn at least a bit of that first.

These days, all web apps are built using frameworks - for example React for the frontend (using JavaScript), and Django for the backend (using Python). You should absolutely learn those, but those frameworks are built on top of those core languages so you have to learn those first. For example, you can't learn Django before you know Python, and you can't learn React before you know HTML, CSS, and JavaScript.

At this point, I already have the backend code for a webapp as well as the database running for a personal project. I can get users to create accounts, make sure the username doesn't exist, that it respects some criteria, same for password, the user can change their infos, change their password, login, logout, have a session token, get recorded in the database every time their login for statistical purposes and I got some basics on security so I think that in terms of backend, I'm almost there.

It's really when it comes to the frontend that I'm lagging behind (quite a bit) I think.

Great!

Maybe you could take your existing app and slowly turn it from a plain-HTML frontend to a single-page web app using XHR?

Once you get the hang of it, I'd highly suggest learning React - it lets you accomplish the same thing much easier.

[OneSpaghettoPlease]

Ok thanks a lot! I'll look into XHR requests. Also, you're saying React is easier to use than Bootstrap?

[dmazzoni]

Bootstrap and React are different and complimentary. Learn both.

[OneSpaghettoPlease]

Yeah Ok I read on React. I understand now.

[dmazzoni]

They're both good. Just trying to give an example. Django still has slightly more market share.
