Python noob here so bear with me..I'm trying to count the occurrences of 'w' in a list using just a for loop and if statement.

Here's my code:

```
items = ["whirring", "calendar", "wry", "glass", "", "llama","tumultuous","owing"]

acc_num = 0

for i in range(len(items)):
  if w in i:
    acc_num = acc_num + 1

print acc_num

```
