问如何检查对象是否为"matplotlib.collections.PolyCollection“类型

对于特定任务( Link )，我希望检查对象是否为：

代码语言：javascript
复制
matplotlib.collections.PolyCollection

或a：

代码语言：javascript
复制
matplotlib.lines.Line2D

对象。

我累得像这样：

代码语言：javascript
复制
 if isinstance(handle, matplotlib.collections.PolyCollection):

但这不起作用。如果想测试两个变量h和句柄是否具有相同的类型，如何检查它们是否都是matplotlib.collections.PolyCollection对象或matplotlib.lines.Line2D对象？

下面是所讨论的代码，它修改了上面链接中的解决方案：

不幸的是，它给了我一个错误：

代码语言：javascript
复制
    Traceback (most recent call last):

        if not is_inlist(hi, lines):

    AttributeError: 'PolyCollection' object has no attribute 'get_color'

建议对每种类型的matplotlib对象进行案例分析。这是我挣扎的地方。我想改变"is_inlist“函数，并在不同的情况下工作。但案例分析本身还不起作用：

初始问题的解决方案是实际导入为比较箱提供类的模块。

您只是缺少import matplotlib.collections。

下一个错误实际上是不言而喻的。它说不可能比较两个数组。

所以我们假设

h的面部颜色是[[ 0., 0.50196078, 0., 0.5]]，而

handle的面部颜色是[[ 1., 0.64705882, 0., 0.5]]，那么

h.get_facecolor() == handle.get_facecolor()导致[[False False True True]]

现在，两次是假的还是两次是对的还是假的？你不可能知道。因此，您需要使用any()或all()来决定是否想知道其中任何元素是True还是所有元素都是True。

在这里，您需要检查相同的颜色，因此使用all：

np.all(h.get_facecolor() == handle.get_facecolor())
