我正在使用2.3 IDLE而且我遇到了问题.

我需要检查一个数字是否介于两个其他数字10000和30000之间:

if number >= 10000 and number >= 30000:
    print ("you have to pay 5% taxes")

它运作得不好.

我们如何在Freemarker中已经创建的SequenceModel实例中添加值？

例如:我有以下创建List(SequenceModel)的方法:

<#assign x = ["red", 16, "blue", "cyan"]>

现在有办法,我可以在上面的列表中添加另一种颜色吗？

当我构建我的 .NET Core (NETStandard v2.0) 项目时，我收到以下警告：

ViewModels：[FodyPackageReference] Fody：PropertyChanged.Fody 的包引用不包含 PrivateAssets='All'

该警告参考了PropertyChanged.Fody NuGet 包。

虽然警告不会停止构建，但我想解决警告。但是，我不明白它试图传达什么。

我有一个模块test.py,它使用键盘导入*从另一个模块keyboard.py导入函数.

在keyboard.py里面有两个功能:

def get_keys(keyList, timeStamped):
    return event.getKeys(keyList=keyList, timeStamped=timeStamped)

def wait_keys(keyList, timeStamped):
    return event.waitKeys(keyList=keyList, timeStamped=timeStamped)

现在,我在test.py中的测试函数如下所示:

@mock.patch('keyboard.wait_keys')
@mock.patch('keyboard.get_keys')
def test_2(self, mock_waitKeys, mock_getKeys):

    mock_waitKeys.return_value = [['wait_keys!', 0.1]]
    mock_getKeys.return_value = [['get_keys!',0.1]]

    run_blocks(trials,noise,win,expInfo, incorrect, tone1, tone2, experiment_details,allPoints,32,60)            

正如您所看到的,我正在尝试将两个模拟返回值放在适当的位置.

然而,他们的影响似乎是倒置的!

当我在交互式控制台中调用它们而在断点处停止时(或在正常调用时检查值),两个模拟函数返回彼此的假返回值!

从控制台:

get_keys()
Out[2]: [['wait_keys!', 0.1]]
wait_keys()
Out[3]: [['get_keys!', 0.1]]

我是否误解了传递给测试函数的模拟参数的顺序？

这可能与修补keyboard.get_keys而不是test.get_keys有关吗？

谢谢!路易丝

我正在开发一个带有 Gradle 版本7.1.1和 Android Gradle 插件版本的Android 应用程序7.0.0。当我升级到 Gradle 版本7.2和 Android Gradle Plugin 版本时7.1.1，出现以下错误。

我一直在Magnolia 代码示例中的 FreeMarker 代码末尾看到感叹号。例如：

${content.header!}

感叹号叫什么，它有什么作用？

我正在使用请求库发出 HTTP GET 请求。例如（截断）：

requests.get("http://123-fake-api.com")

我已经按照请求模拟装饰器模式编写了一个测试。

import requests
import requests_mock


@requests_mock.Mocker()
def test(m):
    m.get("http://123-fake-api.com", text="Hello!")

    response = requests.get("http://123-fake-api.com").text

    assert response.text == "Hello!"

当我使用pytest运行测试时，出现以下错误。

E       fixture 'm' not found

为什么请求模拟装饰器会抛出“找不到夹具‘m’”错误？我该如何解决？

我最近从 bash 切换到 zsh (MacOS)。自从切换以来，我就没有使用过 pipenv。现在，当我运行任何 pipenv 命令时，我收到以下错误：

$ pipenv install
zsh: /usr/local/bin/pipenv: bad interpreter: /usr/local/opt/python/bin/python3.7: no such file or directory

我使用 pyenv 进行 Python 依赖管理：

$ which python
/Users/ryan.payne/.pyenv/shims/python

我的默认 python 版本是 3.7.3：

$ pyenv versions
  system
  2.7.16
  3.6.8
* 3.7.3 (set by /Users/ryan.payne/.pyenv/version)

似乎 pipenv 没有使用我的 pyenv 版本的 Python。我如何让 pipenv 再次工作？
