[New-bugs-announce] [issue23506] Data Structure of Dict not changing its value as expected

[Stan]

New submission from Stan:

Expected the following code to change the value of the variable, it is not, comment are appreciated at this point.



GUMMIE_BEARS = ''

arr2 = { 'GUMMIE_BEARS' : GUMMIE_BEARS }

arr2['GUMMIE_BEARS'] = 'hello world'

print arr2['GUMMIE_BEARS']


print 'and this too' + GUMMIE_BEARS + '<---should be' # point #1


Expected output at point #1 should have 'hello world' contained within the string, it does not however.

# I note this description:
# Mutable variables – such as dictionaries and lists – are passed by reference, 
# and so if your function accepts mutable argument, it may modify the contents of that mutable variable 
# outside the scope of the function.

Thank You.
