Some Very Basic Python

Hello readers,

Rather than trying to wow you with some mega complicated code snippets; which you might not understand, and I probably couldn’t really explain, I figured maybe on occasion I’d throw out some very basic programming to encourage some interest.

Python is a scripting language, and with a simple interpreter it can do some really useful stuff.

To grab an interpreter and install python you should visit or if you are on Linux you can check to see which version of python you have installed via command line by typing: python –version .

For the purpose of this tutorial I was using Geany on Linux Mint 18 and python 2.7 as well as Ninja IDE (after I found it and discovered that I liked it.)

First things first, remember to save whatever python code you start scripting with the .py extension. All languages have specific extensions that denote which type of document they are and python is no exception.

Some Basics

i = 1000
while i >=1:
i = i – 1
print (“counting”)

The above script counts forward to 1000 and says counting between each number. In this case we are telling the compiler that i should equal 1000, and that while i is less than or equal to 1, it should count forward while printing the value as well as the word counting. The syntax here is simple enough, an equals sign means equals by itself, a > means less than, while a < means greater than. The semicolon declares the while statement but could also declare an if statement, or an else statement.

That all seems confusing but you’ll get a better understanding of it as we go.

def countdown():
while i > 0:
yield i
i -= 1

for i in countdown():

In this case we are counting down instead of up. We’ve removed the word counting from our code and now it’s only counting down from 5. The yield command is important here as without it the countdown would continue forever. (Unless we stop it by pressing control c.)

Indentation is important but the editor will chide you into correcting it.

The python standard libraries are available online, by version. There is a drop down box on this page that displays all of the different versions.

If you found this article compelling enough go check out and before you know it you’ll have dozen or even hundreds of example scripts to tinker with. This was just after a few days of playing with what they teach.

I not only am not stopping anytime soon, I’m just getting started. Maybe you are too?

*Collected from around internet a neat code snippet (I didn’t write it but it worked in python 2.7)

Port Scanner

#!/usr/bin/env python
import socket
import subprocess
import sys
from datetime import datetime

# Clear the screen‘clear’, shell=True)

# Ask for input
remoteServer    = raw_input(“Enter a remote host to scan: “)
remoteServerIP  = socket.gethostbyname(remoteServer)

# Print a nice banner with information on which host we are about to scan
print “-” * 60
print “Please wait, scanning remote host”, remoteServerIP
print “-” * 60

# Check what time the scan started
t1 =

# Using the range function to specify ports (here it will scans all ports between 1 and 1024)

# We also put in some error handling for catching errors

for port in range(1,1025):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = sock.connect_ex((remoteServerIP, port))
if result == 0:
print “Port {}:      Open”.format(port)

except KeyboardInterrupt:
print “You pressed Ctrl+C”

except socket.gaierror:
print ‘Hostname could not be resolved. Exiting’

except socket.error:
print “Couldn’t connect to server”

# Checking the time again
t2 =

# Calculates the difference of time, to see how long it took to run the script
total =  t2 – t1

# Printing the information to screen
print ‘Scanning Completed in: ‘, total
