Example 1: Rearrange 2D List Using Nested List Comprehension In this first example, we are going to usenested list comprehensionto rearrange the 2D list: transposed=[[row[i]forrowinoriginal]foriinrange(len(original[0]))]print(transposed)# [[1, 3, 5], [2, 4, 6]] ...

>>> from heapq import heapify, heappop, heappush >>> data = [1, 3, 5, 7, 9, 2, 4, 6, 8, 0] >>> heapify(data) # rearrange the list into heap order >>> heappush(data, -5) # add a new entry >>> [heappop(data) for i in range(3)] # fetch the three smallest entr...
The output of the above code will be[1, 2, 3, 5, 8], as thesort()method rearranges the numbers in ascending order. If you want to sort the elements in descending order, you can use thereverseparameter of thesort()method: # Sort the list in descending ordernumbers.sort(reverse=True...
This is useful for applications which repeatedly access the smallest element but do not want to run a full list sort:>>> >>> from heapq import heapify, heappop, heappush >>> data = [1, 3, 5, 7, 9, 2, 4, 6, 8, 0] >>> heapify(data) # rearrange the list into heap order...
>>> heapify(data) # rearrange the list into heap order >>> heappush(data, -5) # add a new entry >>> [heappop(data) for i in range(3)] # fetch the three smallest entries [-5, 0, 1] 11.8 十进制浮点计算(金融等行业系统开发中常用到) ...
