Before that, I'd never learnt anything from this area of knowledgefield of study.

I considered myself more a humanitarianies kind of person rather than a logic,al and analytical one.

Humanitarian -----> someone working in charity organizations (like UNESCO)

Humanities -----> subjects such as foreign languages, literature, and social sciences

I've always loved to read fiction, read books on psychology and economics, listen to music, and play the guitar.

Repeated "read" in the second part of the list; not repeating it makes it sound like you're listing the types of books you read, rather than the things you like.

AtDuring my school years, I had better grades in history, geography, and languages than in math or physics.

To begin withlearning programming, I learned HTML/CSS markup languages.

I liked making the structure of websitedesigning website structures at first, but then I got bored.

I tried to godive deeply and into learning real programming languages like PHP and Javascript, that are also related to web development, but they didn't work out for me.

I got thea book called 'Learn Python The Hard Way' and spent a half year studying it, from May untill November 2018.

"'til" is the shortened version of "until" and is used more often in casual conversations.

It was amazing experience and I'm happy that I found that particular book, which helped me to learn programming.

The hardest thing that I've ever done is learning pYrogramming.

humanitarian is when things like international aid, donating money, philanthrophy, etc. I got the impression you were referring more to the humanities, which is things like literature and philosophy, as opposite to science and math.

Then, after almost half a yearsix months, I started learning Python.

"almost half a year" is not wrong, but it sounds a bit unnatural to me.

or "six months"

I went through it at a slow pace, trying to do everything at 100 percent correctly.

It was an amazing experience and I'm happy that I found that particular book, which helped me to learn programming.

I won't say that the book made me a professional, but it letallowed me to discover the wonderful world of code.

You could also say "let me discover" but not "let me to discover" as you originally had it.
