Introduction to PyKX section 3 Exercise 10

Posted by ziong on September 27, 2024 at 4:11 pm
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.
```
tab_BTC.get(['volume', 'close', 'date'], tab_BTC['date'] == kx.q.max(tab_BTC))
```
it returns all rows without filtering the date with last date.

see attached.

seems that this should work like this (returns 180 row):
```
tab_BTC[tab_BTC['date'] == kx.q.max(tab_BTC['date']), ['volume', 'close']]
```
