title: How to find total amount of memory used by python process/object in windows
body: <p>I have some script that loads a lot of data to memory.
  I want to know how efficient the data stored in memory. 
  So, I want to be able to know how many memory was used by python before I loaded data, and after I loaded data.
  Also I wondering, if it is some way to check memory usage of complex object.
  Let say i have nested dictionary with different types of data inside. How can i know how many memory used by all data in this dictionary.
  Thanks,
  Alex</p>
