python - Creating array out of list -

my code this:

for register in registerlist1:      parentlist1.append(register._getparent().getname())     classlist1.append(register.getaddress())     classlist1.append(register.getdirection())      classlist1.append(parentlist1)     classlist1.append(classlist1)     print classlist1      parentlist1=[]     classlist1=[]     classlist1=[] 

output:

[['b'], [1000, 'in']] [['c'], [1001, 'out']] 

i want store each output in array this:

classlist1[0] =[['b'], [1000, 'in']] classlist1[1] =[['c'], [1001, 'out']] 

note: registerlist1 contains instance gives me address , direction.

can me here??

you should simplify code , build lists directly, , build outer list appending:

class_list  = [] register in registerlist1:     class_list.append([         [register._getparent().getname()],         [register.getaddress()), register.getdirection()     ])  print class_list 

the above code builds nested lists in 1 go.
