Debian Programming :: How To Find Total Size Of A List Object In Byte

Assuming there are two list objects a1, a2.

a1 = ['
']
a2 =['hi
']

len() built-in function gives total number of elements in the list object.
len(a1) gives 1. len(a2) gives 1 also.

Code: Select all$ python
Python 2.7.3 (default, Sep  9 2012, 17:41:34)
[GCC 4.7.1] on linux2

[Code]......

I thought there exists a built-in function that gives total size of a list object in byte. So using the function produces 1 for a1, 3 for a2. I haven't found such function or module yet.
