python - Creating multiple sql databases of the same structure using Peewee -

-

i looking create 26 separate sql databases, each same structure. (i.e. 1 each letter of alphabet), ideally can access dictionary or similar [i.e. access database corresponding letter a database["a"] ].

i have following code, generates 1 sql database (in case letter a) using peewee. 

from peewee import * database_location_a = "c:\\database\\a.db" data_sql_a= sqlitedatabase(database_location_a, threadlocals=true, pragmas=(("synchronous", "off"),))             class basemodel(model):     class meta:         database = data_sql_a  class main_table(basemodel):     file_name = charfield(primary_key = true)     year = charfield()  data_sql_a.connect()     data_sql_a.create_tables([main_table])

there parts of code can loop on (e.g. can create dictionary of file locations). however, stuck given location coded class basemodel, how loop on [i.e. need 26 separate classes, , if so, can create without needing copy/paste class 26 times]? , similarly, given main_table uses basemodel, need 26 separate instances of class well?

i may going wrong way, want know approach take adapt code create multiple files, without needing copy/paste multiple times?

i able running solution using peewee database proxy object.

from peewee import * database_proxy = proxy()  class basemodel(model):     class meta:         database = database_proxy  # use proxy our db.  class main_table(basemodel):     file_name = charfield(primary_key = true)     year = charfield()  import string db_names = string.ascii_lowercase # print(db_names) # abcdefghijklmnopqrstuvwxyz  ''' loop on characters in string , create databases in current folder of script ''' db_name in db_names:     database = sqlitedatabase('{}.db'.format(db_name), threadlocals=true, pragmas=(("synchronous", "off"),))     database_proxy.initialize(database)     database_proxy.connect()     database_proxy.create_tables([main_table])

according proxy documentation, can use database_proxy variable database object after calling database_proxy.initialize(database). example, connect() , create_tables() being called on database through database_proxy.

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
