Python pattern from from incresing and descresing sequnce of numbers

This post will explain the logic, code and Syntax for pattern program in Python Programming. In this post you will understand how to right the code of a pattern which have the sequence in  descreasing and incresinng sequence.

 Pattern Code-

def python_pattern(n):
    for i in range(0, n):
        if n/2 >= i:
            for j in range(1, i+1):
                print(j, end=" ")
            print("\r")
        else:
            for j in range(1, n - i + 1):
                print(j, end=" ")
            print("\r")
n=10python_pattern(n)

Output:

1 2

1 2 3

1 2 3 4

1 2 3 4 5

1 2 3 4

Pyhtan * Pattern Program with Space

As all of us knows that as we used to print the pattern program in C, C++, JAVA,Net, etc. to make comfortable to the new user as we started learning that programming language.

In the same way to make confidence and learn syntax and logic writting style in Python. We can practice as many prgram for this i am showing to all of you more than 20 pattern program code in Python.
You can copy and paste these code and even test at your own system. Users can modify these Codes too.

Python pattern program with space and Star(*) 

Program Code-

def python_pattern(n):
    # outer loop will handle number of rows    

    # n in this case    

    for i in range(0, n):
        # inner loop will handle number 

          of columns for space printing        

       for k in range(0, n-i):
            # printing stars            

            print("  ", end="")
        # inner loop will handle number of columns 

        for star printing        

       for j in range(0, i + 1):
            # printing stars

            print("* ", end="")
            # ending line after each row

        print("\r")
    # Driver Code

n = 6python_pattern(n)

Output-

Palindrome JAVA Code 2 Programming Logic and Code with Syntax

This is individual description list of program which is mentionmed in first page of JAVA, part of programming tutorial i will try to explanin more than 50 java * pattern program, Which are asked in interview and online exams and unveristy exam with diferrent logic for the same type of pattern

 Top 100+ Sql Server Interview Questions

A palindromic number is a number  that is the same when written forwards or backwards
 always be same, i.e., of the form . The first few palindromic numbersare therefore  are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121. 

class PalindromeExample
{  

 public static void main(String args[])
{  

  int r,sum=0,temp;    

  int n=555;//It is the number variable to be checked for palindrome  

  

  temp=n;    

  while(n>0)
{    

   r=n%10;  //getting remainder  

   sum=(sum*10)+r;    

   n=n/10;    

  }    

  if(temp==sum)    

   System.out.println("palindrome number ");    

  else    

   System.out.println("not palindrome");    

}  

}
