Python 打印三角形字母图案程序

使用 for 循环编写一个 Python 程序来打印三角形字母图案。

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

print("====Print Triangle Alphabets Pattern ====")

for i in range(0, rows):
    alphabet = 65
    for j in range(rows, i, -1):
        print(end = ' ')
    for k in range(0, i + 1):
        print('%c' %(alphabet + k), end = ' ')
    print()

本示例使用 while 循环以三角形图案显示字母。

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

i = 0

while(i < rows):
    alphabet = 65
    j = rows
    while(j > i):
        print(end = ' ')
        j = j - 1
    k = 0
    while(k <= i):
        print('%c' %(alphabet + k), end = ' ')
        k = k + 1
    print()
    i = i + 1

Enter Triangle Alphabets Pattern Rows = 10
