Exercise:
Loop through the numbers 0 to 7 (7 included) and concatenate a string
with the numbers comma-separated. You should have a comma at the end of the string.

What I have tried:

for num in range(8):
num = str(num) + ","

I may not understand the question right since it's not my main language but what is wrong?

Not even sure what you try to do. Your code have no output and second line look wrong.
Use the debugger to see what your code is doing, and experiment to what works as expected and wjat don't.

There is a tool that allow you to see what your code is doing, its name is debugger. It is also a great learning tool because it show you reality and you can see which expectation match reality.
When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

Debugging techniques for PHP programmers[^]
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
