Hi there
I have a list of dummy objects which have the attributes 'location',
'name', 'gender'.
Now I want to rebuild this list in order to avoid redundancies on
objects with the same 'location'.
Example:
#------------------------------------------------------------------
class Dummy:
pass
a = Dummy()
a.location = 'tokio'
a.name = 'john'
a.gender = 'm'
b = Dummy()
b.location = 'tokio'
b.name = 'peter'
b.gender = 'm'
c = Dummy()
c.location = 'madrid'
c.name = 'susan'
c.gender = 'f'
d = Dummy()
d.location = 'london'
d.name = 'alex'
d.gender = 'm'
persons = [a, b, c, d]
print "loc name gender"
print "---------------------"
for obj in persons:
print "%s - %s - %s" % (obj.location, obj.name, obj.gender)
#------------------------------------------------------------------
The output reads like this:
loc name gender
---------------------
tokio john m
tokio peter m
madrid susan f
london alex m
I want to create this list (where name and gender are lists):
loc name gender
-----------------------------
tokio [john, peter] [m]
madrid [susan] [f]
london [alex] [m]
How can I do this?
Thanks in advance.
Nico
