  • Looking for a bit of coding advice!
    I'm a new coder too. What helps me is finding a good place to learn the most basic principles and having 2-5 things I want to do. I started with codedex.io , learning Python and HTML and then took their courses and moved on looking for projects with tutorials. Little steps one by one. The rest is practice breaking things down into tiny steps. Source: over 3 years ago
  • self learning towards a web dev career
    I think you should focus on HTML, CSS, and JS, starting with HTML. I just started HTML on a website called codedex.io. Pretty cool so far but I feel like I'm getting into a brand new thing haha. Source: over 3 years ago
  • A beginner in python
    I've been learning Python on a website called codedex.io for about 6 months. It's been great for me so far. I just started on Classes and Objects. Give them a try, you might like them. Source: over 3 years ago
  • Question
    Python is a great language to start as a beginner! I don't know how new you are but a good place to learn some basics is codedex.io (also where I started from zero, 6 months ago haha). Source: over 3 years ago
  • Is it possible to learn Programming and coding? not a tech graduate.
    You should start from the basics with a platform like codedex.io they do Python! It was straightforward to use for me (I'm 32). Give them a try. I am still a beginner, but I was starting from zero. Source: over 3 years ago
