Python to Implement Bubble, insert, select simple sort instance, python bubble
The Python implementation in this article bubble, insert, and simple sorting examples are suitable for beginners of Python to learn data structures and algorithms from the basics. The example is simple and easy to understand. The specific code is as follows:
#-*-Coding: cp936-*-# insert sort def insertSort (a): for I in range (len (a)-1): # print, I for j in range (I + 1, len (a): if a [I]> a [j]: temp = a [I] a [I] = a [j] a [j] = temp return a # Python's Bubble Sorting def bubbleSort (alist ): for passnum in range (len (alist)-1, 0,-1): # print alist, passnum for I in range (passnum ): if alist [I]> alist [I + 1]: temp = alist [I] alist [I] = alist [I + 1] alist [I + 1] = temp return alist # select and sort def selectionSort (alist) in Python ): for I in range (len (alist)-1, 0,-1): maxone = 0 for j in range (1, I + 1 ): if alist [j]> alist [maxone]: maxone = j temp = alist [I] alist [I] = alist [maxone] alist [maxone] = temp return alistalist = [54,26, 93,17, 77,31, 44,55, 20] # print bubbleSort (alist) alist = [54,26, 93,17, 77,31, 44,55, 20] print selectionSort (alist)
If you are interested, you can test the examples in this article. I believe there will be new gains.
Select sorting, fast sorting, Bubble sorting, heap sorting, insert sorting, and the running speed of the basic sorting program.
It depends on time complexity.
O (n ^ 2), O (n ^ 2), O (n ^ 2), O (nlog 2 n), O (nlog 2 n ), O (nlog 2 n ),

I know this and hope to help you!
