I have a newby type question on how global variables work between modules.
I have a module test2.py that defines a global variable as well as two functions to operate on that variable. A script test1.py imports the three names and prints out values of the global between operations, and the results aren't what I expected. Here is the module, test2.py ------------------------------------ glbl = 25 def inc_glbl(): global glbl glbl += 1 def get_glbl(): global glbl return glbl ------------------------------------ and here is the test script, test1.py ------------------------------------- from test2 import glbl, inc_glbl, get_glbl print 'glbl orig ', glbl inc_glbl() print 'glbl postinc ', glbl new = get_glbl() print 'glbl from func ', new -------------------------------------- I would expect the three values to be ( 25, 26, 26 ), but what I get is c:\projects\pitcher_model>test1.py glbl orig 25 glbl postinc 25 glbl from func 26 --------- It seems that the references to 'glbl' are seeing a local copy, rather than the original. This is not what the literature says should be happening. I am looking for a way to share data between modules. Can you advise me on my error? I am using Python 2.3.2 from ActiveState, on Windows XP Pro. Thank you David -- http://mail.python.org/mailman/listinfo/python-list
