string - changing data in a struct in python -

-

i pretty new in python, , have problem don't know how solve.

for example, have struct members such administrator, berit, etc:

default_data = { 'administrator': {     'name': 'admin',     'pw': 'secret',     'is_author': false,     'is_admin': true } 'berit': {      'name': 'berit',     'pw': 'apa',     'is_author': false,     'is_admin': false  }

this data accessible via method method:

def defaultdata(): """provides default data gruyere."""  return copy.deepcopy(default_data)

i want md5 hash on passwords not in plaintext, have no idea how access fields such 'pw' , reassign new value in python.

here's guess might be:

stored_data = data.defaultdata() member in stored_data:    field in member:        if field=='pw':            'pw' = md5.new(salt+pw).hexdigest()    // how access value?

the values in stored_data dictionaries. iterate on values , apply algorithm:

stored_data = data.defaultdata() data in stored_data.values():     data['pw'] = md5(salt + data['pw']).hexdigest()  pprint import pprint pprint(stored_data)

output

{'administrator': {'is_admin': true,                    'is_author': false,                    'name': 'admin',                    'pw': '33e7cb694fb6fb2f848af6774d9ff138'},  'berit': {'is_admin': false,            'is_author': false,            'name': 'berit',            'pw': '00c10978330d65eb0cb739a629b6ed15'}}

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
