Hello All,
I am trying to measure memory used in a Python
program. Also, I would like to gather some statistics
about object usages. For example, I would like to be
able to see how much time it takes to search for an
item in a dict object, how many times it has to access
the symbol table to retrieve a specific item, and
things like that. Furthermore, I would like to be able
to see how a symbol table is created, how many items
it has, how many times it is accessed during
execution, etc.
Python profiler gives timing information about
functions/methods. For example, it doesn't show how
many times a dictionary object is accessed to retrieve
a key or how much time it takes.
The dis module doesn't provide detailed information
either. For the following code,
dict = { 'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
print dict.has_key('e')
The dis module provides the following:
0 LOAD_GLOBAL 0 (dict)
3 LOAD_ATTR 1 (has_key)
6 LOAD_CONST 1 ('e')
9 CALL_FUNCTION 1
12 PRINT_ITEM
But this doesn't really help to see what's going on
with the symbol table.
Any help is greatly appreaciated. Thanks a lot!
Regards,
Dave
