Python Program to Print Inverted Triangle Numbers Pattern

Write a Python program to print an inverted triangle numbers pattern using nested for loop range with an example.

rows = int(input("Enter Inverted Triangle Number Pattern Rows = "))

print("====The Inverted Triangle Numbers Pattern====")

for i in range(1, rows + 1):
    for j in range(1, i):
        print(end = ' ')
    for k in range(1, rows - i + 2):
        print(k, end = ' ')
    print()
Python Program to Print Inverted Triangle Numbers Pattern

This Python example displays the inverted triangle pattern of numbers using a while loop.

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

print("========")
i = 1

while(i <= rows):
    j = 1
    while(j < i):
        print(end = ' ')
        j = j + 1
    k = 1
    while(k <= rows - i + 1):
        print(k, end = ' ')
        k = k + 1
    print()
    i = i + 1
Enter Rows = 13
