newArray.sort(sortBy('number',false)) V8 引擎 sort 函数只给出了两种排序 InsertionSort 和 QuickSort,数量小于10的数组使用 InsertionSort,比10大的数组则使用 QuickSort。

下面的示例显示了sorted()如何将传递给它的字符串进行遍历,并在输出中对每个字符进行排序: >>>string_number_value='34521' >>>string_value='I like to sort' >>>sorted_string_number=sorted(string_number_value) >>>sorted_string=sorted(string_value) >>>sorted_string_number ['1', '2', '3', ...
unique、nunique,也是仅适用于series对象,统计唯一值信息,前者返回唯一值结果列表,后者返回唯一值个数(number of unique) sort_index、sort_values,既适用于series也适用于dataframe,sort_index是对标签列执行排序,如果是dataframe可通过axis参数设置是对行标签还是列标签执行排序;sort_values是按值排序,如果是dataframe对...

This means you can sort str types as well. The example below shows how sorted() iterates through each character in the value passed to it and orders them in the output:Python >>> string_number_value = "34521" >>> sorted(string_number_value) ['1', '2', '3', '4', '5'] >...
