Defining Multiple Objects at Once

[Larry Bates]

I don't know Cantera, but I think this
will help.

Something like the following works well:

rdict={'R1': None, 'R2': None, 'R3': None}
for reac in rdict.keys():
    #
    # Store an instance of Reactor class in
    # the dictionary with key reac
    #
    rdict[reac]=Reactor()

Then you can reference them with:

rdict['R1'].temperature()

You could also put them in a list instead
of a dictionary but then you would have to
reference them with an index:

rlist=[]
#
# Append an instance of Reactor class in
# the list.
#
rlist.append(Reactor())
rlist.append(Reactor())
rlist.append(Reactor())

then you can reference them with:

rlist[0].temperature()
rlist[1].temparature()

All depends on how you need to process them.
