Python程序打印直帕斯卡三角形字母图案

编写一个Python程序，使用for循环打印右帕斯卡三角形字母图案。

rows = int(input("Enter Right Pascal Alphabets Triphants Rows = "))

print("====The Right Pascal Triphabets Pattern====") alphabet = 65

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

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

这个Python例子使用一个while循环来打印字母的直角三角形模式。

rows = int(input("Enter Right Pascal Alphabets Triangle Rows = " ))

print("====The Right Pascal Triphabets Pattern====") alphabet = 65 i = 0

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

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

Enter Right Pascal Alphabets Triangle Rows = 12
====The Right Pascal Triangle Alphabets Pattern====
