Thank I get the methods. 
Python 2.6.2

I just leaning python , before using gawk/ksh.

#!/usr/bin/env python

a= dict()
a["PrintA"]= ["batch1","batch2","batch3"]
a["PrintB"] = ["batch4","batch5"]

a["PrintA"].append("batch6")

print a
for k in sorted(a.keys()):
    for j in sorted(a[k]):
     print k , j

Output 
{'PrintA': ['batch1', 'batch2', 'batch3', 'batch6'], 'PrintB': ['batch4', 'batch5']}
PrintA batch1
PrintA batch2
PrintA batch3
PrintA batch6
PrintB batch4
PrintB batch5
