Python : Sqlite Insert Libraries of varying size into table


My answer accepted in stackoverflow.

Below is the code that I have written to create an insert statement for python which accepts the table name and dictionary. This will allow the varying size dictionaries to directly map into an Insert statement. Similar logical can be used for UPDATE statement as well.


import sqlite3
def create_insert_string(table_name,input_dictionary,conn_db):
#validate connection
c = conn_db.cursor()
#Check if the table is existing in the database if not throw error
table_exist=c.execute('SELECT COUNT(*) FROM sqlite_master WHERE type=\'table\' AND name=\''+table_name+'\'');
if table_exist.fetchone()[0]==0:
return 'Error'
insert_str = 'INSERT INTO '+table_name+' ( '
count=0;
for keys in input_dictionary.keys():
if count == 0:
insert_str=insert_str+ ' '+keys
else:
insert_str=insert_str+ ', '+keys
count=count+1
count=0;
insert_str=insert_str+' ) VALUES ( '
for keys in input_dictionary.keys():
if count == 0:
insert_str=insert_str+ ' :'+keys
else:
insert_str=insert_str+ ', :'+keys
count=count+1
insert_str=insert_str+' )'
return insert_str
# Main Program
conn = sqlite3.connect('C:\\PYTHON_SCRIPTS\\test.db')
dict={'column1':'value1','column2':'value2'}
insert_string=create_insert_string('test',dict,conn)
print(insert_string)
c = conn.cursor()
c.execute(insert_string,dict)
conn.commit()
c.close()

Python Scripting : Get max Last Modified Date using os.walk


Below is the code that i have written to get the max Lsat Modified Date of the files in all folders that i can delete all the folders that are not not being used by me for a long time.

#-*-coding:utf8;-*-
#qpy:2
#qpy:console
import os
import datetime
print “This is console module”
def comparefiletime(in_file,in_date) :
lastdate =datetime.datetime.fromtimestamp(os.path.getmtime(in_file))
if lastdate > in_date:
return lastdate
else:
return in_date

def getmaxdatefolders(in_root_fldr):
for foldern, sfoldern, filen in os.walk(in_root_fldr):
maxdate = datetime.datetime(1900, 1, 1,00,00)
for fileo in filen:
maxdate = comparefiletime(os.path.join(foldern,fileo),maxdate);
printmax date for the folder %s is %s’ %(foldern, maxdate)

getmaxdatefolders(‘storage/emulated/0/’);
