Python: For every 2 items in list? [duplicate]

Question

The default for loop only iterates through each item at a time. How can I make it so I can iterate through every 2 items?

Answer 1

You can use the slice notation:

for item in items[::2]:
   print(item)

If you want to iterate pairwise every 2 items, you can do this:

for item1, item2 in zip(items[::2], items[1::2]):
   print(item1, item2)

Answer 2

you can use:

for item in items[::2]:
   <your_code>
