Basics · CodeItRaw

Start from zero: functions, conditions, loops and lists. Every later topic builds on these.

Key ideas

A function takes input and hands back its answer with return; print only writes to the screen.
if picks a path by a question; == asks whether two things are equal, % gives the remainder.
for repeats the same work: range(1, n + 1) counts from 1 to n, for v in values walks a list.
Start a variable before the loop (a counter, a total, a best), update it inside, return it at the end.

count = 0
for v in values:
    if v > 0:
        count += 1
return count

Each lesson explains one idea from zero and ends with a few tasks. Lessons open in order; the explanation can be read at any time.

Boss

Fizz Counter

Function

The boss opens when every lesson of the topic is finished. Solve it too and the topic is complete, and the topics after it open.
