【Python】字母表的循环迭代

 字母循环迭代器

    def forward(letter, jump):
        """字母表上的循环迭代器"""
        if letter.islower():
            start_character = ord('a')
        else:
            start_character = ord('A')
        start = ord(letter) - start_character
        offset = ((start + jump) % 26) + start_character
        result = chr(offset)
        return result

执行1：

print(forward("a", 2))
print(forward("A", 5))
print(forward("E", 2))

执行结果

 执行2：

    for i in range(8):
        print(forward("a", i))

执行结果

数字迭代

print("-"*10 + " 分割线 " + "-"*10)
    for i in range(2):
        print(i)

执行结果
