python实现插入排序

代码如下@.·.@

# *-*   coding: utf-   *-*

if __name__ == '__main__':
    def insert_sort(l):
        for i in xrange(,len(l)):
            tmp = l[i]
            key = i-
            while (key >=  and tmp < l[key]):
                l[key+] = l[key]
                key-=

            if ((key+) != i):
    #            l.insert(key,tmp)
    #        else:
    #        m.insert(key+,tmp)
                l[key+] = tmp
        return l

    print insert_sort([,,,,,,,,])
