from eval_expr import*
from math import *
from eval_expr import eval_expr
eval_expr("sqrt(90)", True)

Gives error:

"C:\Users\sanje\AppData\Roaming\Texas Instruments\TI-Nspire CX CAS Premium Teacher Software\PyExtract\eval_expr.py", line 38, in  eval_expr
TypeError: Invalid number format

In the last version I get the following:

import ti_st
print(help(ti_st))

object <module 'ti_st'> is of type module
name -- ti_st
readST --
readSTNum --
readSTLst --
writeST --
evalFunc --
writeSTLst --
getKey --
wait --
get_platform --
disp_clr --
getmouse --
get_time_ms --

So there are also readSTNum, readSTLst and writeSTLst. I do not know so much of Python and the TI-NSpire to do anything with that functions. But maybe you? Also I do not know how to list the parameters of the undocumented functions. Is there a way?
By the way: Great work!

I keep getting an "Invalid number format" exception on line 38 when calling either function. I have everything set up correctly, and it works on the Student Software, but not on my Nspire. I'm not sure what's going wrong.

I tested the functions today, but they do not work anymore. ;-(

Checked it with the original TI Student Software and two calculators, a CX II-T and a CX II-T CAS.
I used the simple expression
eval_expr("sqrt(90)",True) - that one from your example. (Tested False or no second param also)
On the CAS I get: line 38, in eval_expr
TypeError: Invalid number format
That is the line: res = readST("tmppy_") # retrieve stored value

On the non-CAS I get: py", line 37, in eval_expr
TypeError: Variable storage failed
And thats the line: writeST("tmppy_", 'strsub(string('+str(expr)+'),"/","$%$")') # eval and store

Calculator-Software: 5.3.0.564 on both calculators.

Any chance to fix the problem, or has evil TI blocked that method?

Still the same issue
Tried on another laptop. I am using 6.0.3.374
Can you kindly send me your file, so I can compare.
