Python删除指定下标的字符串

删除指定下标：正负均可

def str_del_index(str,index):
    """
    Args:
    	str:进行操作的字符串
    	index:要删除的位置
    Returns:
    	_str:删除完成后的字符串
    """
    _str = ''
    if index < 0:
        str = str[::-1] # 字符串反转
        index = 0 - index - 1
        for i in range(len(str)):
            if i == index:
                continue
            _str += str[i]
        _str = _str[::-1]
    else:
        for i in range(len(str)):
            if i == index:
                continue
            _str += str[i]
    return _str

示例：

>>> str = "2022-11-09"
>>>print(str_del_index(str,-2))
>2022-11-9
