I said I would never deal with code, and here I am running beginner Python exercises on Codedex. Music plays in the background while I think out loud. I type lines wrong and catch the same mistake again later. Modulo confuses me before it clicks. The BMI exercise took a turn. Put it on and work alongside me.
The Codedex route
Codedex is the platform I'm learning Python on. It costs money, and I think it's worth the money.
Vibe coding is the plan, and the goal is an attempt at Python. The background music comes from StreamBeats. The session stays mostly quiet, with a few thoughts out loud while I figure things out.
- Hello World
- Patterns
- Initials in ASCII
- A letter to my future self
- Variables and data types
- Fahrenheit to Celsius
- BMI and Python operators
Variables and data types
I write one variable for each type. The integer is XP set to 30, then I do the float, a name for the string, and the boolean.
- Integer is a whole number
- Float is a decimal number
- String is text
- Boolean is true or false
Modulo and the BMI result
Modulo confuses me for a while. The first example uses six and two and returns zero, and I can't explain it at first. The sign gives back what is left over, not the split itself. Then it clicks.
For the BMI exercise I declare the values first, then plug in my own numbers. The answer comes out at 26.6, which lands in the overweight range. Next up is the BMI of an athlete.
- Nine with the modulo sign and two: count how many twos fit in nine, and whatever does not fit is the answer
- Eight with the modulo sign and two gives zero
