小编Rap*_*tor的帖子

我需要将范围转换为连续数字。范围以整数为单位，结果应该是相同的。这是我到目前为止所拥有的：

import numpy as np

mydata = np.array (
[49123400, 49123499],
[33554333, 33554337])

numbers_list = np.empty((0))
base_dir = "/foo.csv"

for x in mydata:
    numbers = np.arange(x[0], x[1]+1)
    numbers_list = np.append(numbers_list, numbers, axis=0)
np.savetxt(base_dir, numbers_list, delimiter=";")

我希望看到的是这样的列表：

49123400,
49123401,
49123402,...
49123499,
33554333,
33554334,...
33554399

但我得到的是：

4.912340000000000000e+11 and so on...

我哪里错了？当我执行附加操作时，为什么会从 int 变为 float？

我已经在这个类的构造方法中定义了 Request 。

/**
* @var Request
*/
protected $request;

public function __construct(Request $request)
{
    $this->request = $request;
}

现在，当我尝试在这样的函数中检索帖子数据时：

public function postListsAction()
{
    dd($this->request->get("title"));
}

我收到以下错误：

无法自动装配服务“App\Controller\ListController”：方法“__construct()”的参数“$request”引用类“Symfony\Component\HttpFoundation\Request”，但不存在这样的服务。

我该如何解决这个问题？

根据CJK Unicode Ideographs，中文、日文和韩文的 Unicode 范围是：

\n
• 中日韩统一表意文字 (4E00-9FCC)[\\u4E00-\\u9FCC]
\n
• 中日韩统一表意文字扩展 A (3400-4DB5)[\\u3400-\\u4DB5]
\n
• 中日韩统一表意文字扩展 B (20000-2A6D6)[\\ud840-\\ud868][\\udc00-\\udfff]|\\ud869[\\udc00-\\uded6]
\n
• 中日韩统一表意文字扩展 C (2A700-2B734)\\ud869[\\udf00-\\udfff]|[\\ud86a-\\ud86c][\\udc00-\\udfff]|\\ud86d[\\udc00-\\udf34]
\n
• CJK 统一表意文字扩展 D (2B840-2B81D)\\ud86d[\\udf40-\\udfff]|\\ud86e[\\udc00-\\udc1d]
\n
• CJK 兼容表意文字 (F900-FA6D/FA70-FAD9) 中的 12 个字符，但实际上是 CJK 统一表意文字[\\uFA0E\\uFA0F\\uFA11\\uFA13\\uFA14\\uFA1F\\uFA21\\uFA23\\uFA24\\uFA27-\\uFA29]
\n

但我检查了中文标点符号\xef\xbc\x9f ( \\uFF01) 和\xef\xbc\x81 ( \\uFF1F) 不在范围内。我想知道所有汉字（包括标点符号）的Unicode范围是多少？

实际上，我正在研究Python汉字的正则表达式，但我无法获取中文括号内的内容：

import re\nsample3 = "\xe3\x80\x8c\xe5\x9c\xa8\xe7\x9c\x8b\xe6\x98\x9f\xe6\x98\x9f\xe5\x97\x8e\xef\xbc\x9f\xe9\x96\xa3\xe4\xb8\x8b\xef\xbc\x81\xe3\x80\x8d"\n\nresult = re.search(r"\\u300c([\\u4e00-\\u9fff\\u31c0-\\u31ef\\u31f0-\\u31ff\\u3200-\\u32ff\\u3300-\\u33ff\\u3400-\\u4dbf\\u4dc0-\\u4dff\\u4e00-\\u9fff]+)\\u300d", sample3)\nprint(result)\n

没有结果。我想摘录这句话：

\n

\xe5\x9c\xa8\xe7\x9c\x8b\xe6\x98\x9f\xe6\x98\x9f\xe5\x97\x8e\xef\xbc\x9f\xe9\x96\xa3\xe4\xb8\x8b\xef \xbc\x81

\n

仅供参考，上面这句话的意思是：“先生，您在看星星吗？”

谢谢。 …

如何防止我的SWF反编译？

从反编译预防的角度来看, ActionScript 1/2和ActionScript 3之间有什么区别吗？

这是以下问题的相反问题:

我可以在函数内调用xsl函数吗？我只想比较之前的值和当前值.例如:

<xsl:value-of select="//row[(position()-1)]/MONTH_ID" />

但是,下面的代码是可以的:

<xsl:value-of select="number(position())-1" />

在JavaScript我能做到

console.log(variable-name)

工作得很好.

与此问题类似,我有一个CSV货币汇率,精确到小数点后9位.

我应该为列使用哪种数据类型？

我想FLOAT,DOUBLE和DECIMAL(11,11)他们产生以下警告之一:

1. 超出行X列"column_name"的范围值
2. 在行X处为列'column_name'截断的值

当我使用SHOW WARNINGS命令.
