I'm a python newbie, currently in the process of moving
parts of my work from Matlab to python + Numeric.
When using python interactively, I often need something
like the Matlab "whos" command.
In Matlab "whos" returns a list of all variables:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
>> a = 4;
>> b = [1 2 3; 4 5 6];
>> whos
Name Size Bytes Class
a 1x1 8 double array
b 2x3 48 double array
Grand total is 7 elements using 56 bytes
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
is there any way of doing something similar in python?
A recent post by Michael Chermside, in the thread
"How to get the 'name' of an int" suggests the following for
the slightly different task of listing names and values:
for name, value in locals().iteritems():
print "%s = %s" % (name, value)
any suggestions of how I could change this to name, type?
On a related note, the Matlab commands "clear all; pack"
clears all variables in the current namespace and starts
garbage collection. Is there a corresponding python idiom?
