python 字典数据的插入

以字典的形式,把控起来还是比较方便的. 举个例：
d = {‘k1’: ‘v1’, ‘k2’: ‘v2’}

insert = 'insert into table (%s) values %s'
l = [(c, v) for c, v in d.items()]
columns = ','.join([t[0] for t in l])
values = tuple([t[1] for t in l])
cursor = conn.cursor()
print cursor.mogrify(insert, ([AsIs(columns)] + [values]))

keys = d.keys()
columns = ','.join(keys)
values = ','.join(['%({})s'.format(k) for k in keys])
insert = 'insert into table ({0}) values ({1})'.format(columns, values)
print cursor.mogrify(insert, d)
