python- how to display size of all variables

I want to print the memory size of all variables in my scope simultaneously.

Something similar to:

for obj in locals().values():
    print sys.getsizeof(obj)

But with variable names before each value so I can see which variables I need to delete or split into batches.

Ideas?

Solution

  • You can iterate over both the key and value of a dictionary using .items()

    from __future__ import print_function  # for Python2
import sys

local_vars = list(locals().items())
for var, obj in local_vars:
    print(var, sys.getsizeof(obj))
