Steps to reproduce the issue

Hello, it seems .z.pi does not work in pyq. Below is just a dummy example:

ubuntu@host:~$ q
q)cnt:0
q).z.pi:{ cnt::cnt+1 ; show value x;};
q)cnt
1
q)cnt
2
q)1+1
2
q)3+4
7
q)cnt
5
q)\\
ubuntu@host:~$ workon venv
(venv) ubuntu@host:~$ pyq
Python 2.7.12 (default, Dec  4 2017, 14:50:18) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> q()
q)cnt:0
q).z.pi:{ cnt::cnt+1 ; show value x;};
q)cnt
0
q)1+1
2
q)cnt
0
q)\
>>> 

Expected result

I expect variable cnt to increase at each call

Actual result

cnt does not increase at each call

Workaround

N/A If you know workaround, please provide it here.

q) prompt in the PyQ is pseudo-prompt and does not support all features of kdb+ prompt. It was created to simplify debugging.

I will leave it to @abalkin to decide if this feature can be enhanced to support .z.pi.

Thanks for the answer, indeed it's what I expected. The reason I want to override .z.pi is because I have sandbox environments for my user which they can spin up themselves, and I would like to log all queries.

do we support .z.pi nowadays ? it's very useful to custom output, such as add colors, etc.
