Python Program to Print Right Triangle of Mirrored Numbers Pattern

Write a Python program to print right triangle of mirrored numbers pattern using for loop.

rows = int(input("Enter Right Triangle Mirrored Numbers Rows = "))

print("====The Right Triangle of Mirrored Numbers Pattern====")

for i in range(1, rows + 1):
    for j in range(1, i + 1):
        print(j, end = ' ')
    for k in range(i - 1, 0, -1):
        print(k, end = ' ')
    print()

This Python example prints the right angled triangle pattern of mirrored numbers using a while loop.

rows = int(input("Enter Right Triangle Mirrored Numbers Rows = "))

print("====The Right Triangle of Mirrored Numbers Pattern====")
i = 1

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