print join(' ', sort {$a <=> $b} @array), "\n"; 打印结果是: 复制代码代码如下: 1 2 4 8 16 32 与之一样的是: 复制代码代码如下: sub numerically { $a <=> $b }; print join(' ', sort numerically @array), "\n"; 这个很容易理解哦,它只是按自然数的顺序进行sort,偶就不细讲...

In Python, sorting data structures like lists, strings, and tuples can be achieved using built-in functions like sort() and sorted(). These functions enable you to arrange the data in ascending or descending order. This section will provide an overview of how to use these functions. ...
def sort_numeric_strings(nums_str): result = sorted(nums_str, key=lambda x: int(x)) return result nums_str = ['4','12','45','7','0','100','200','-12','-500'] print("Original list:") print(nums_str) print("\nSort the said list of strings(numbers) numerically:") print...
48.Write a Python program to sort a given list of strings (numbers) numerically using lambda. Original list: ['4', '12', '45', '7', '0', '100', '200', '-12', '-500'] Sort the said list of strings(numbers) numerically: ...
Arrays are slightly different from lists. They can only contain one type of data structure, and they are much faster to work with numerically. >>> from Numeric import * >>> s = arrayrange(0,2*pi,0.1) #"arange" also >>> print s ...

If you have a list with a number but in string type and wanted to sort in reverse order, first you need to convert it to int type by usingkey=inttosort()orsorted()functions. Note that, here the sorted list will be of string type but the data is numerically sorted by ascending order...
