Python 打印直角三角形字符图案程序

编写一个 Python 程序，使用 for 循环打印直角三角形字符图案。

rows = int(input("Enter Right Triangle Characters Pattern Rows = "))

print("====The Right Triangle of Characters Pattern====")
alphabet = 65

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

此 Python 示例 使用 while 循环打印直角三角形字符图案。

rows = int(input("Enter Right Triangle Characters Pattern Rows = "))

print("====The Right Triangle of Characters Pattern====")
alphabet = 65
i = 1

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

Enter Right Triangle Characters Pattern Rows = 14
