Question

I’m looking for the best way to Pythonize the: for (int i = 0; i < itemsCount; i++)

Any thoughts?

Thanks in advance

If you are iterating over the items in some container, just iterate over that container; don’t use the index unless you need to.

Right:

slots = [1, 2, 3, 7]
for slot in slots:
    print cards[slot]

Wrong (or at least “writing C/C++/Java/C#/whatever in Python”):

slots = [1, 2, 3, 7]
for i in range(len(slots)):
    print cards[slots[i]]

If you need an index for some other purpose (e.g. you’re going to modify the container), the Python way is enumerate():

for i, slot in enumerate(slots):
    print cards[slot]
    slots[i] += 1
