Python: Create a SQLite table within the database

Python SQLite Database: Exercise-3 with Solution

Write a Python program to connect a database and create a SQLite table within the database.

Structure of agent_master table:

agent_code char(6),
agent_name char(40),
working_area char(35),
commission decimal(10,2),
phone_no char(15) NULL);

Sample Solution:

Python Code :

import sqlite3
from sqlite3 import Error
def sql_connection():
   try:
     conn = sqlite3.connect('mydatabase.db')
     return conn
   except Error:
     print(Error)
def sql_table(conn):
   cursorObj = conn.cursor()
   cursorObj.execute("CREATE TABLE agent_master(agent_code char(6),agent_name char(40),working_area char(35),commission decimal(10,2),phone_no char(15) NULL);")
   print("\nagent_master file has created.")
   conn.commit()
sqllite_conn = sql_connection()
sql_table(sqllite_conn)
if (sqllite_conn):
 sqllite_conn.close()
 print("\nThe SQLite connection is closed.")

Sample Output:

agent_master file has created.

The SQLite connection is closed.

Alternate solution:

Python Code :

import  sqlite3

# connect to the database.
conn  =  sqlite3 . connect ( 'mydatabase.db' )
# defining a cursor
cursor  =  conn . cursor ()

# creating the table (schema) agent_master
cursor . execute ( """
CREATE TABLE agent_master(agent_code char(6),
agent_name char(40),working_area char(35),
commission decimal(10,2),phone_no char(15) NULL);
""" )
print("\nagent_master file has created.") 
# disconnecting ...
conn . close ()
print("\nThe SQLite connection is closed.")

Sample Output:

agent_master file has created.

The SQLite connection is closed.

How to make a chain of function decorators?

from functools import wraps

def makebold(fn):
    @wraps(fn)
    def wrapped(*args, **kwargs):
        return "<b>" + fn(*args, **kwargs) + "</b>"
    return wrapped

def makeitalic(fn):
    @wraps(fn)
    def wrapped(*args, **kwargs):
        return "<i>" + fn(*args, **kwargs) + "</i>"
    return wrapped

@makebold
@makeitalic
def hello():
    return "hello world"

@makebold
@makeitalic
def log(s):
    return s

print hello()        # returns "<b><i>hello world</i></b>"
print hello.__name__ # with functools.wraps() this returns "hello"
print log('hello')   # returns "<b><i>hello</i></b>"
