Make a simple local database (not networked):

import nosqlite db = nosqlite.Client(DATA+'localdb').db db

Database 'db'

Database 'db'

Insert a document in a table.

db.table.delete()

db.table.insert({'a':10, 'b':20})

db.table.find_one()

{u'a': 10, u'b': 20}

{u'a': 10, u'b': 20}

db.table.insert(a=3, b=17)

list(db.table.find(b=17))

[{u'a': 3, u'b': 17}]

[{u'a': 3, u'b': 17}]

Do something more complicated that uses pickle.

x = var('x') K.<a> = NumberField(x^2 - x -1) E = EllipticCurve([a,1,1-a,a,1])

db.curves.insert({'ainvs':E.a_invariants(), 'cond':E.conductor(), 'T':E.torsion_order()})

db.curves.find_one()

{u'ainvs': (a, 1, -a + 1, a, 1), u'cond': Fractional ideal (30*a + 703),
u'T': 1}

{u'ainvs': (a, 1, -a + 1, a, 1), u'cond': Fractional ideal (30*a + 703), u'T': 1}
