python简单尝试

python看了好多遍，没怎么coding，这里简单写个

 1 #!/usr/bin/python
 2 def printSide(qsort):
 3     def inner_print(ls,begin,end):
 4         print("(%d,%d)"%(begin,end))
 5         qsort(ls,begin,end)
 6     return inner_print
 7 
 8 @printSide
 9 def qsort(ls,begin,end):
10     if begin>=end:
11         return
12     tmp = ls[begin]
13     pos = begin
14     for mov in range(begin+1, end+1):
15         if ls[mov]<tmp:
16             pos += 1
17             ls[pos],ls[mov] = ls[mov],ls[pos]
18     ls[begin],ls[pos] = ls[pos],ls[begin]
19     if pos - 1 > begin:
20         qsort(ls,begin,pos-1)
21     if pos + 1 < end:
22         qsort(ls,pos+1,end)
23 
24 def myGenerator(num):
25     for i in range(0,num):
26         yield i
27 
28 if __name__ == "__main__":
29     ls = []
30     for i in myGenerator(10):
31         ls.append(int(input("Please input number: ")))
32     print(ls)
33     qsort(ls,0,len(ls)-1)
34     print(ls)
