Python 编程：打印反向数字三角形

编写一个 Python 程序，使用 for 循环以反向模式打印数字三角形。

rows = int(input("Enter Triangle Reverse Numbers Pattern Rows = "))

print("====The Triangle of Numbers in Reverse Pattern====")

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

此Python示例使用 while 循环以降序或反向顺序打印数字三角形模式。

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

print("====The Triangle of Numbers in Reverse Pattern====")
i = rows

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 Rows = 9
====The Triangle of Numbers in Reverse Pattern====
        9 
       8 9 
      7 8 9 
     6 7 8 9 
    5 6 7 8 9 
   4 5 6 7 8 9 
  3 4 5 6 7 8 9 
 2 3 4 5 6 7 8 9 
1 2 3 4 5 6 7 8 9
