Python 打印左箭头字母图案程序

使用 for 循环编写一个 Python 程序来打印左箭头字母图案。

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

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

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

这个 Python 示例 使用 while 循环打印字母图案的左箭头。

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

print("====The Left Arrow Alphabets Pattern====")
alphabet = 65
i = rows - 1

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

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

Enter Left Arrow Alphabets Pattern Rows = 12
