cassandra - 如何使用 pycassa 打印 superCF

Question

以下代码失败（ValueError: too many values to unpack , under pycassaShell）
有什么方法可以漂亮地打印超列吗？

cf = pycassa.ColumnFamily(pool, 'Super1')
res = cf.get_range()
for key, col in res:
    print '\n\n', key, ':'
    for k, c in col:
        print k, '=>', c

Answer 1

像这样

cf = pycassa.ColumnFamily(pool, 'Super1')
res = cf.get_range()
for key, col in res:
    print '\n\n', key, ':'
    for i in col.keys():
        print i, '=>', col[i]
