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()
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
