Python学习——排序

排序
data = [22,1,4,7,9,32,56,43,2,7,4,9,1]
print (len(data))
count = 0
for j in range(1,len(data)):
····for i in range(len(data)-j):
········if data[i] > data[i+1]:
············ tmp = data[i+1]
············data[i+1] = data[i]
············data[i] = tmp
········count += 1
····print(data)

结果为：
