选择排序法（SelectionSorting）python

def selection_sort(num=[]) :
	for i in range(len(num)) :
		mini = i 
		for j in range(i+1, len(num), 1) :
			if num[j] < num[mini] :
				mini = j
		if mini != i :
			num[i], num[mini] = num[mini], num[i]
	return num

num = ['1', '2', '4', '3', '6', '8', '7', '9', '5']
selection_sort(num)
print(num)

'''
['1', '2', '3', '4', '5', '6', '7', '8', '9']
