nitvars2 1.1
new versions of globals,locals,tracer and other functions..
Requires Python: >=3.5

# nitvars
Python variables v2 package
Python version 3 or later


add new version of globals, locals
globals fix
add tracer, scaner frame info
add exec v2 = multiline exec and return result
add multiline  lambda  lambda x,y:e2('x=x+1;print(x);x+y')

for see and test all functions run nitvars_test.py  or "py -m nitvars" or
from nitvars.nitvars_test import * 
main()



Select test ['0=testglobals2', '1=testlocals2', '2=exec2test', '3=lambda2test', '4=testscaner', '5=tracertest', '6=callhelptest', 'all=all tests']:

######## testglobals2
Now get testvar. testvar in globals!
var "testvar" in simple globals()=NOT FOUND!
Not found "testvar" in levels {'nitvars.nitvars', '__main__'}
var "testvar" in globals2()=None
Not found "testvar" in levels {'module'}
var "testvar" in realglobals()=None
testvar in [level:id]: None
Why?  globals() find globals only in this script(in nitvars.py..)

Now set testvar with "global testvar"
var "testvar" in simple globals()=SET OK!
var "testvar" in globals2()=SET OK!
Not found "testvar" in levels {'module'}
var "testvar" in realglobals()=None
testvar in [level:id]: {'nitvars.nitvars': 2538507971952}
Why?  global x set globals only in this script(in nitvars.py..)

Now set testvar2 with "globals()[testvar]"
var "testvar" in simple globals()=SET OK!2
var "testvar" in globals2()=SET OK!2
Not found "testvar" in levels {'module'}
var "testvar" in realglobals()=None
testvar in [level:id]: {'nitvars.nitvars': 2538507972016}
Why?  globals() set globals only in this script(in nitvars.py..)

Now set testvar2 with nitvars "globals2()[testvar]"
var "testvar" in simple globals()=SET OK!3
var "testvar" in globals2()=SET OK!3
var "testvar" in realglobals()=SET OK!3
testvar in [level:id]: {'nitvars.nitvars': 2538507972144, '__main__': 2538507972144}
Why?  globals2() is real globals, globals() is ...
