Big Data Analytics is the process of collecting, organizing and analyzing large sets of data to discover patterns and other useful information. Big data analysts / scientists can help organizations to better understand the information contained within the data and will also help identify the data that is most important to the business and future business decisions. For data analysis, most of work is being done using either of two languages: R or Python. This blog is created to learn both over a period of time, in explanatory manner, step by step, so that we could use both languages for any data related analysis / mining / statistical computations.

Python sample program tutorial
Here is a beginner learning / basic Python program to create a small desktop app / widget for fun:
This was my first desktop applictaion built in Python. Took less than 5 minutes.

This is another test program using tkinter package:
import tkinter as tk
counter = 0
def counter_label(label):
def count():
global counter
counter += 1
label.config(text=str(counter))
label.after(1000, count)
count()
root = tk.Tk()
root.title("Counting Seconds")
label = tk.Label(root, fg="green")
label.pack()
counter_label(label)
button = tk.Button(root, text='Stop', width=25, command=root.destroy)
button.pack()
root.mainloop()
