Python program to Print Sandglass Number Pattern

Write a Python program to print sandglass number pattern using for loop. 

rows = int(input("Enter Sandglass Number Pattern Rows = "))

print("====Sandglass Number Pattern====")

for i in range(1, rows + 1):
    for j in range(1, i):
        print(end = ' ')
    for k in range(i, rows + 1):
        print(k, end = ' ')                
    print()

for i in range(rows - 1, 0, -1):
    for j in range(1, i):
        print(end = ' ')
    for k in range(i, rows + 1):
        print(k, end = ' ')      
    print()
Python program to Print Sandglass Number Pattern

This Python example prints the numbers in a sandglass pattern using a while loop.

rows = int(input("Enter Sandglass Number Pattern Rows = "))

print("====Sandglass Number Pattern====")
i = 1
while(i <= rows):
    j = 1
    while(j < i):
        print(end = ' ')
        j = j + 1
    k = i
    while(k <= rows):
        print(k, end = ' ')
        k = k + 1
    print()
    i = i + 1

i = rows - 1
while(i >= 1):
    j = 1
    while(j < i):
        print(end = ' ')
        j = j + 1
    k = i
    while(k <= rows):
        print(k, end = ' ')
        k = k + 1   
    print()
    i = i - 1
Enter Sandglass Number Pattern Rows = 10
