Python: Insert values to a table from user input
Python SQLite Database: Exercise-7 with Solution
Write a Python program to insert values to a table from user input.
Sample Solution:
Python Code :
import sqlite3
conn = sqlite3 . connect ( 'mydatabase.db' )
cursor = conn.cursor ()
#create the salesman table
cursor.execute("CREATE TABLE salesman(salesman_id n(5), name char(30), city char(35), commission decimal(7,2));")
s_id = input('Salesman ID:')
s_name = input('Name:')
s_city = input('City:')
s_commision = input('Commission:')
cursor.execute("""
INSERT INTO salesman(salesman_id, name, city, commission)
VALUES (?,?,?,?)
""", (s_id, s_name, s_city, s_commision))
conn.commit ()
print ( 'Data entered successfully.' )
conn . close ()
if (conn):
conn.close()
print("\nThe SQLite connection is closed.")
Sample Output:
Salesman ID: 5 Name: Jhon Edin City: New York Commission: 5 Data entered successfully. The SQLite connection is closed.

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
