I use a webservice to pull some data from it everyday & update it on my MySQL database. I'll make around 600 calls to this service. The webservice response is very slow (takes around 30 minutes to complete 600 transactions) & during this time, the MySQL is also giving slow ...

Python - How can I insert data into a MySQL database? Python: A Simple Step-by-Step SQLite Tutorial. SQLite is a self-contained, server-less, config-free transactional SQL database engine.

Python gained the sqlite3 module all the way back in version 2.5 which means that you can create SQLite database with any current Python without downloading any additional dependencies. Mozilla uses SQLite databases for its popular Firefox browser to store bookmarks and other various pieces of information. In this article you will learn the following: How to create a SQLite databaseHow to insert data into a tableHow to edit the dataHow to delete the dataBasic SQL queries This article will be similar in function to the recent SQLAlchemy tutorial that appeared on this site earlier this month.

How to Create a Database and INSERT Some Data Creating a database in SQLite is really easy, but the process requires that you know a little SQL to do it. First we have to import the sqlite3 library and create a connection to the database. Here we use the INSERT INTO SQL command to insert a record into our database. Append one file to another - Software Development. Twisted. Twisted is an event-driven networking engine written in Python and licensed under the open source ​MIT license. Twisted runs on Python 2 and an ever growing subset also works with Python 3. Twisted makes it easy to implement custom network applications.

Reactor pattern - Wikipedia. Structure[edit] Properties[edit] Benefits[edit] The reactor pattern completely separates application specific code from the reactor implementation, which means that application components can be divided into modular, reusable parts.

Also, due to the synchronous calling of request handlers, the reactor pattern allows for simple coarse-grain concurrency while not adding the complexity of multiple threads to the system. Limitations[edit] The reactor pattern can be more difficult to debug[2] than a procedural pattern due to the inverted flow of control. See also[edit] References[edit] External links[edit]

17.6. sched — Event scheduler — Python 3.5.2 documentation. Source code: Lib/sched.py The sched module defines a class which implements a general purpose event scheduler: class sched.scheduler(timefunc=time.monotonic, delayfunc=time.sleep) The scheduler class defines a generic interface to scheduling events.

It may also be used to go back from monitor mode to managed mode. Entering the airmon-ng command without parameters will show the interfaces status. Usage. Python Scripting Tutorial (Shell) Shell Scripting One of the most useful packages for unix shell scripters in python is the subprocess package.

The simplest use of this package is to use the call function to call a shell command: #! /usr/bin/env pythonimport subprocess subprocess.call("ls -l", shell=True) This script will call the unix command "ls -l" and print the output to the console. . #! This script will open the process on unix "tail -500 mylogfile.log", read the output of the command and print it to the console.

The first thing the script does is create a variable "proc", this is the process object returned by the call to subprocess.Popen. Shell - Calling an external command in Python.

Automate the Boring Stuff with Python. Checking and replying to email is a huge time sink.

Of course, you can’t just write a program to handle all your email for you, since each message requires its own response. But you can still automate plenty of email-related tasks once you know how to write programs that can send and receive email. For example, maybe you have a spreadsheet full of customer records and want to send each customer a different form letter depending on their age and location details. Commercial software might not be able to do this for you; fortunately, you can write your own program to send these emails, saving yourself a lot of time copying and pasting form emails. You can also write programs to send emails and SMS texts to notify you of things even while you’re away from your computer. Much like HTTP is the protocol used by computers to send web pages across the Internet, Simple Mail Transfer Protocol (SMTP) is the protocol used for sending email.

Airodump-ng [Aircrack-ng] Description Airodump-ng is used for packet capturing of raw 802.11 frames and is particularly suitable for collecting WEP IVs (Initialization Vector) for the intent of using them with aircrack-ng.

If you have a GPS receiver connected to the computer, airodump-ng is capable of logging the coordinates of the found access points. Additionally, airodump-ng writes out several files containing the details of all access points and clients seen. Usage.
