python dataframe 一列转换list dataframe列转为number类型 下面的例子都以train_df举例,因为常用于观察训练集数据的特征 1、从整个DataFrame中找出数值为数字的列: train_df.select_dtypes(include=np.number) 1. 如果再进一步,只想获取列值为数字的列名: train_df.select_dtypes(include=np.number).columns.values...

找一个数用最快的方式在数列里找到我首先想到的就是二分查找(当然可能还有别的方式)。 所以我想用二分查找的方式找到这个单独的数,但是二分查找基于数列有序的时候,所以首先把数列快速排序(本想写个快排,但是懒,直接用sort了) 对于排序好的数列我想到的是可以找到中间的数,然后看它是不是和左右相等,来判断单独...
