Iterate a dictionary and store value in array using Phython : I have a dictionary [{'abc':10,'efg':20,'def':30},{'abc':40,'xya':20,'def':50}] and I would like to create an array abc[] and store corresponding value in that array.so the output should look like 
         abc[10,40]
         def[30,50]
         efg[20] and so on, using python.
