Sqlite3 naming db file with a variable in python

Question

How can I use the current date to name my db file so when it runs it creates a db file which is named after the current date. This is what I have so far:

import sqlite3
import time


timedbname = time.strftime("%d/%m/%Y")

# Connecting to the database file
conn = sqlite3.connect(???)

with this error its the same with '/' or '-' or '.' in "%d/%m/%Y":

conn = sqlite3.connect(timedbname, '.db')
TypeError: a float is required
27.01.2016

Answer 1

Try using:

time.strftime("%d-%m-%Y")

I guess it doesn't work because of the slashes in the generated date.

Answer 2

You can't have dashes in your table name. Also it can't start with a digit.

import sqlite3
from datetime import date

timedbname = '_' + str(date.today()).replace('-','_')

# Connecting to the database file
conn = sqlite3.connect(':memory:')
cursor = conn.cursor()

cursor.execute('''CREATE TABLE %s (col1 int, col2 int)''' % (timedbname))
cursor.execute('''INSERT INTO %s VALUES (1, 2)''' % (timedbname))
cursor.execute('''SELECT * FROM %s'''%timedbname).fetchall()

Answer 3

This worked:

import sqlite3
import time


timedbname = time.strftime("_" + "%d.%m.%Y")
conn = sqlite3.connect(timedbname + '.db')
