编写一个Python程序，使用for循环打印字母右三角的反向模式。
rows = int(input("Enter Right Triangle of Rev Alphabets Rows = " ))
print("==== Reverse Pattern中字母的右三角====") alphabet = 65
for i in range(rows - 1, -1, -1): for j in range(rows - 1, i - 1, -1): print('%c' %(alphabet + j), end = ' ' ) print()
这个Python模式的例子使用一个while循环，以反向或降序的方式打印字母的直角三角形。
rows = int(input("Enter Right Triangle of Rev Alphabets Rows = ")
print("==== Reverse Pattern====") alphabet = 65 i = rows - 1
while(i >= 0): j = rows - 1 while(j >= i): print('%c' %(alphabet + j), end = ' ' ) j = j - 1 print() i = i - 1
Enter Right Triangle of Rev Alphabets Rows = 13
