Python

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

---------------------------------------------------------------------------------

Program 1-

Source Code- Pycharm IDE

def python_pattern(n):  

    for i in range(0, n):      

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

            print("* ", end="")      

        print("\r")
    n = 6

    python_pattern(n)

F:\web\venv\Scripts\python.exe F:/web/pattern.py

Program 2

Python pattern program with space and Star(*) 

Program Code-

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

    # n in this case    for i in range(0, n):
        # inner loop to handle number 

        #of columns for space printing        

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

            print("  ", end="")
        # inner loop to 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 = 6

python_pattern(n)

Output-

Program 3- Palindrome No Program in Python

In this 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.

Program 4:- Pattern Program Number Sequence

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