  Introduction to PyKX section 3 Exercise 10

  Hi all,

  for the exercise 10:

  Return all close prices and volume from tab_BTC for the last date

  I wonder that the suggested solution may be incorrect.

  <pre class=”hljs language-q”>tab_BTC.get([‘volume’, ‘close’, ‘date’], tab_BTC[‘date’] == kx.q.max(tab_BTC[‘date’]))

  it returns all rows without filtering the date with last date.

  see attached.

  seems that this should work like this (returns 180 row):

  <pre class=”hljs language-q”>tab_BTC[tab_BTC[‘date’] == kx.q.max(tab_BTC[‘date’])].get([‘volume’, ‘close’])
