Python Program to Print a Simple Number Pattern

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

rows = int(input("Enter Simple Numeber Pattern Rows = "))

print("====Printing Simple Number Pattern====")

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

This example program displays the numbers in the right angled triangle pattern using a while loop.

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

print("=======")

i = 1

while(i <= rows):
    j = 1
    while(j <= i):
        print(j, end = ' ')
        j = j + 1
    print()
    i = i + 1

Enter Rows = 9
