打印金字塔字母图案的Python程序

编写一个Python程序，使用for循环来打印金字塔字母图案。

rows = int(input("Enter Alphabets Pyramid Pattern Rows = " ))

print("====The Pyramid of Alphabets Pattern====") alphabet = 64

for i in range(1, rows + 1): for j in range(1, rows - i + 1): print(end = ' ') for k in range(i, 0, -1): print('%c' %(alphabet + k), end = '') for l in range(2, i + 1): print('%c' %(alphabet + l), end = ' ') print()

这个Python例子使用一个while循环来打印字母的金字塔模式。

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

print("========") alphabet = 64 i = 1

while(i <= rows): j = 1 while(j <= rows - i): print(end = ' ') j = j + 1 k = i while(k > 0): print('%c' %(alphabet + k), end = '') k = k - 1 l = 2 while(l <= i): print('%c' %(alphabet + l), end = '' ) l = l + 1 print() i = i + 1

Enter Rows = 12
