      3  2  1
   4  3  2  1
5  4  3  2  1

Explanation:

• Row 1: No. of cols = 1, spaces = 4, value = 1
• Row 2: No. of cols = 2, spaces = 3, value = Row ... 1 = 2 1
• Row 3: No. of cols = 3, spaces = 2, value = Row ... 1 = 3 2 1
• ...

Solution:

for row in range(1, 6):
    # printing out spaces
    print('   ' * (5 - row), end='')
    # printing out patterns
    for col in range(row, 0, -1):
        print(col, end='  ')
    print()
