打印右箭头字母图案的Python程序

编写一个Python程序，使用for循环来打印右箭头字母图案。

rows = int(input("Enter Right Arrow Alphabets Pattern Rows = "))

print("====The Right Arrow Alphabets Pattern====") alphabet = 65

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

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

这个Python例子使用while循环打印字母的右箭头模式。

rows = int(input("Enter Right Arrow Alphabets Pattern Rows = " ))

print("====The Right Arrow Alphabets Pattern====") alphabet = 65 i = 0

while(i < rows): 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

i = rows - 2 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 Right Arrow Alphabets Pattern Rows = 12
====The Right Arrow Alphabets Pattern====
