Python Sorting Algorithm instance summary, python Sorting Algorithm instance

This example summarizes the python selection sorting algorithm. Share it with you for your reference. The details are as follows:

Code 1:

def ssort(V):#V is the list to be sorted  j = 0 #j is the "current" ordered position, starting with the first one in the list  while j != len(V): #this is the replacing that ends when it reaches the end of the list    for i in range(j, len(V)):   #here it replaces the minor value that it finds with j position      if V[i] < V[j]:     #but it does it for every value minor than position j        V[j],V[i] = V[i],V[j]    j = j+1   #and here's the addiction that limits the verification to only the next values  return V 

Code 2:

def selection_sort(list):   l=list[:]  # create a copy of the list   sorted=[]  # this new list will hold the results   while len(l):  # while there are elements to sort...     lowest=l[0]    # create a variable to identify lowest     for x in l:    # and check every item in the list...       if x<lowest:      # to see if it might be lower.         lowest=x     sorted.append(lowest)    # add the lowest one to the new list     l.remove(lowest)    # and delete it from the old one   return sorted

Code 3

a=input("Enter the length of the list :")# too ask the user length of the list l=[]# take a emty list for g in range (a):# for append the values from user   b=input("Enter the element :")  # to ask the user to give list values   l.append(b)  # to append a values in a empty list l print "The given eliments list is",l for i in range (len(l)):# to repeat the loop take length of l   index=i  # to store the values i in string index   num=l[i]  # to take first value in list and store in num   for j in range(i+1,len(l)):  # to find out the small value in a list read all values     if num>l[j]:    # to compare two values which store in num and list       index=j      # to store the small value of the loop j in index       num=l[j]      # to store small charecter are value in num   tem=l[i]  # to swap the list take the temparary list stor list vlaues   l[i]=l[index]  # to take first value as another   l[index]=tem print "After the swping the list by selection sort is",l
