Reading gcode variable from python?

are there any solution that help me read gcode variable from python?
Linuxcnc has commands such as: debug,print. These command can display gcode variables when program reach this command but i'd like to read variables via python to show these value on GUI.

hi
you read the lines in as a TXT and as you got the linenumber running fom hal you know where the Gcode is

Tks for the answer but could you please explain more detail? , i want these variable values keep update without using DEBUG or PRINT command when linuxcnc is running in auto mode.

what is in this variables you want to read
and how does a word line looks you use
so there may be a better way to taken them

It's a named variable.
example: #<_variable>.
i would like to create a part of GUI that show variable values.

It is not possible to access gcode variables with python interface. The only way to interface gcode with some outer signal is via M62 - M68 mcodes.
