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

1 2

1 2 3

1 2 3 4

1 2 3 4 5

1 2 3 4

1 2 3

1 2

Palindrome number program in Pythan

In this post i will explain the palindome number program in python and also to expalin the same i also created a youtube video so you can check also complete step by step and also output in IDE. 

Palindrome number program in Pythan

Palindrome No Program in Python-

num = int(input("enter a number: "))
temp = num
rev = 0while temp:
    rev = (rev * 10) + (temp % 10)
    temp = temp // 10if num == rev:
    print("No is palindrome")
else:
    print("No is not palindrome")

Output-

When entered Item is- 747

   No is Palindrome.

when entered Item is- 67

   No is notb Palindrome.

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-

                 * 

              * * 

           * * * 

        * * * * 

     * * * * * 

  * * * * * *
