Python 对序列进行舍入时出错

Python 对序列进行舍入时出错,python,pandas,rounding,Python,Pandas,Rounding,我有一系列的花车。它是数据帧sum()操作的结果。 我需要将其所有元素舍入为整数,但我得到一个错误: [in]: A= mins.sum().iloc[1:]/60 # this line works fine. The .iloc is to get rid of a text column. [in]: print(A) [out]: Min bad 249.5 Min pr-ul 967.57 intra c

AttributeError:“float”对象没有属性“rint”
谁能告诉我这是为什么?我能修好它吗? 我想问题的根源是因为这个系列是“对象”类型的。 但这是什么?它只包含浮点数!!!它是数据帧摘要的结果


提前感谢您按照Mark Dickinson的建议,使用
.astype(float)
将该系列转换为float类型。 在您的情况下,应该使用
A.astype(float).round()


我在数据框中遇到了同样的错误,将列舍入为一个浮点值为我解决了这个问题。多亏了马克·迪金森。

你可以尝试
a.astype(float)
。我已经尝试过了,但也不起作用。…@user3623123:
a.astype(float).round()
应该能起作用。你能展示一下你尝试它时出现了什么错误吗?
