Python 打印字母倒三角形的程序

编写一个 Python 程序，使用 for 循环以倒序打印字母三角形。

rows = int(input("Enter Triangle of Reverse Alphabets Rows = "))

print("====The Triangle of Alphabets in Reverse Pattern====")
alphabet = 65

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

这个 示例 使用 while 循环以降序或倒序打印字母三角形。

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

print("====The Triangle of Alphabets in Reverse Pattern====")
alphabet = 65
i = rows - 1

while(i >= 0):
    j = 0
    while(j < i):
        print(end = ' ')
        j = j + 1
    k = i
    while(k < rows):
        print('%c' %(alphabet + k), end = ' ')
        k = k + 1
    print()
    i = i - 1

Enter Rows = 12
