Python变长参数

感觉Python的变长参数还是蛮好用的，记录下，便于查询。 
def selectsql(self, sqlstr, *condition): 
        arr = sqlstr.split("?") 
        if len(arr) != len(condition) + 1: 
            return 
        rs = "" 
        for i in range(len(arr)-1): 
            rs += arr[i] + str(condition[i]) 
        print(rs) 
def sele(self,sqlstr,**condition): 
        for key in condition: 
            print(key,condition[key])
