diamond format '*' program in python 

print(" Diamond Format \n")
val = eval(input('Enter the value  '))
k=val//2
j=0
for i in range(1,val,2):
 print(' '*k,end='')
 print('*'*i)print(" Diamond Format \n")
val = eval(input('Enter the value  '))
k=val//2
j=0
for i in range(1,val,2):
 print(' '*k,end='')
 print('*'*i)
 k=k-1
 j=i

j=j-2
k=2
#print(' ',j)
for j in range(j,0,-2):
 print(' '*k,end='')
 print('*'*j)
 k=k+1

 k=k-1
 j=i

j=j-2
k=2
#print(' ',j)
for j in range(j,0,-2):
 print(' '*k,end='')
 print('*'*j)
 k=k+1

Berlekamp–Massey algorithm

The Berlekamp–Massey algorithm is an algorithm that will find the shortest linear feedback shift register for a given binary output sequence. The algorithm will also find the minimal polynomial of a linearly recurrent sequence in an arbitrary field. I have used sage for computing this program. # Berlekamp-Massey Algorithm #from __future__ import print_function s = [GF(2)(0), 0, 1, 0, 0, 0, 0, 0, 1, 1, 0] #input sequence n = len(s) C = [GF(2)(1)] B = [GF(2)(1)] temp = [] T = [] L = 0 N = 0 m = -1 print '----- n',n print '-----------------------------------------------------------------------' while N < n: temp = B d = s[N] for i in range(1,L+1): d = d + C[i]*s[N-i] print '----- d ',d if d == 1: T = C temp = [ 0 for i in range(int(N-m))] + temp if len(C) < len(temp): C = C + [0 for i in range(len(temp)-len(C))] else: temp = temp +...

Simple Automation using Python - Atomac in Mac OS X

Image
The Product Automation in MAC OS X is quite easy if we have enough knowledge in the following languages and tools  Bash Scripts  Apple Scripts  Python especially ATOMac Knowledge in Accessibility. For more understanding of the LDTP: http://download.freedesktop.org/ldtp/doc/ldtp-tutorial.pdf LDTP - Tutorial is written by  Nagappan Alagappan. He has given the clear idea and architecture of the LDTP and its working. I have used the contents from the tutorial for knowledge sharing. Following are the few information and contents from  the LDTP - Tutorial. Few interesting key points, Linux Desktop Testing Project (LDTP) i s aimed at producing high quality test automation framework and cutting-edge tools that can be used to test GNU/Linux Desktop and improve it.  It uses the Accessibility libraries to poke through the application's user interface.  This idea has been extended to Microsoft Windows as Cobra , Mac OS X as ATOMa...
