I found a solution for the simulation of access modifier "static final "
in python:
class Mytest:
LOGE_10=(2.302585092994046,)
#Klassenkonstante (static final) use a tuple
#def __init__(self):
def log10(self,x):
return(log(x)/LOGE_10[0])
testmath=Mytest()
print "LOGE_10=%10.8f"%Mytest.LOGE_10[0]," and
log10=%f10.8"%testmath.log10(3)
Mytest.LOGE_10[0]=1
#print "LOGE_10=%10.8f"%Mytest.LOGE_10[0]," and
log10=%f10.8"%testmath.log10(3)
#output:
#LOGE_10=2.30258509 and log10=0.47712110.8
#Traceback (most recent call last):
# File
"C:\Python22\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py",
line 301, in RunScript
# exec codeObject in __main__.__dict__
# File "C:\PyProgs\Static.py", line 13, in ?
# #Mytest.LOGE_10=1
#TypeError: object doesn't support item assignment
#
I think the result is selfexplaining. Unawaited there is another
argument for tuples! One may use it for the definition of global
"Constants" as well.
Hopefully that contribution will be of interest and profit for other
python users. Thanks for your contributions.

PS: Has everyone tried to use classes as elements of tuples? please give
me a hint.
