Equivalent of "whos" command in NumPy
try using: type(VAR_NAME) 
this will output the class type for that particular variable, VAR_NAME
I am new to Numpy and trying to search for a function to list out the variables along with their sizes (both the matrix dimensions as well as memory usage). 
I am essentially looking for an equivalent of the "whos" command in MATLAB and Octave. Does there exist any such command in NumPy?
