When I pass an empty string to a function is a new string object created or does python use some global pre-created object? I know python does this with integer objects under a certain value. For instance, in the following code is a new string object created for each function call?
func(0,'') func(1,'') func(2,'') func(3,'') I tried the following commands in the interactive shell: >> x = '' >> y = '' >> x is y True >> x = 'hello' >> y = 'hello' >> x is y True This leads me to believe that python does reuse existing strings, but once the variables are removed, does the item still exist in the cache? -Farshid -- http://mail.python.org/mailman/listinfo/python-list
