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

Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value:

Example:

def tips_map_values(obj, fn):
  ret = {}
  for key in obj.keys():
    ret[key] = fn(obj[key])
  return ret
users = {
  'Owen': { 'user': 'Owen', 'age': 29 },
  'Eddie': { 'user': 'Eddie', 'age': 15 }
}

print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}

Output:

{'Owen': 29, 'Eddie': 15}
