Question

我正在尝试将我创建的数据帧切成垃圾箱：

picture of dataframe in case it's relevant

# create bins and labels
bins = [575, 600, 625, 650]
labels = [
    "$575-$599",
    "$600-$624",
    "$625-$649",
    "$650-$675"
]

schoolSummary["Spending Range"] = pd.cut(schoolSummary["Per Student Budget"], bins, labels = labels)

由于某种原因，我收到此错误：

---------------------------------------------------------------------------

    235 
    236     return _postprocess_for_cut(fac, bins, retbins, x_is_series,

    338 
    339     if include_lowest:

TypeError: '<' not supported between instances of 'int' and 'str'

我很困惑，因为我根本没有在代码中使用“ <”。我也用过

print(type(schoolSummary["Per Student Budget"]))

，它是一个系列对象，所以我不知道它指的是“ int”和“ str”。我的垃圾箱或标签有问题吗？

由于答辩率低，我无法评论您的问题，

您必须尝试以下操作

Dim EmployeeID As Integer = cbxEmployee.SelectedValue

因为bins = [575, 600, 625, 650] labels = [ "$575-$599", "$600-$624", "$625-$649", "$650-$675" ] for bin_ in bins: schoolSummary["Spending Range"] = pd.cut(schoolSummary["Per Student Budget"], bin_, labels = labels)的类型为bin，而不是int。

对系列进行装箱将返回看似无关的TypeError
