Python Program to Print X Pattern of Numbers

In this Python program, you will learn to print the X pattern of numbers using for loop, while loop, and functions. The below example accepts the user-entered rows, and the nested for loops iterates the rows and columns. Next, the if else in this program will print the numbers in an X pattern.

rows = int(input("Enter Rows = "))

for i in range(rows):
    for j in range(rows):
        if i == j or j == rows - 1 - i:
            print(j + 1, end='')
        else:
            print(' ', end='')
    print()
Enter Rows = 11
1         11
 2       10 
  3     9  
   4   8   
    5 7    
     6     
    5 7    
   4   8   
  3     9  
 2       10 
1         11

You may also try the below code and it will print different numbers on each side of the X pattern.

rows = int(input("Enter Rows = "))

for i in range(2 * rows - 1):
    for j in range(2 * rows - 1):
        if i == j or j == 2 * rows - 2 - i:
            print(j + 1, end='')
        else:
            print(' ', end='')
    print()
Enter Rows = 9
1               17
 2             16 
  3           15  
   4         14   
    5       13    
     6     12     
      7   11      
       8 10       
        9        
       8 10       
      7   11      
     6     12     
    5       13    
   4         14   
  3           15  
 2             16 
1               17

Instead of a For loop, this program uses the while loop to iterate the rows and columns and prints the X pattern of numbers at each position. For more Number pattern programs >> Click Here.

rows = int(input("Enter Rows = "))

i = 0
while i < rows:
    j = 0
    while j < rows:
        if i == j or j == rows - 1 - i:
            print(j + 1, end='')
        else:
            print(' ', end='')
        j += 1
    print()
    i += 1
Enter Rows = 15
1             15
 2           14 
  3         13  
   4       12   
    5     11    
     6   10     
      7 9      
       8       
      7 9      
     6   10     
    5     11    
   4       12   
  3         13  
 2           14 
1             15

This Python program allows the user to enter the rows. Next, the XpatternNumber function uses nested for loops and if else prints the numbers on rows and columns of an X pattern.

def XpatternNumber(rows):
    for i in range(rows):
        for j in range(rows):
            if i == j or j == rows - 1 - i:
                print(j + 1, end='')
            else:
                print(' ', end='')
        print()


n = int(input("Enter Rows = "))
XpatternNumber(n)
