def iconv(filename,scr_type,obj_type):
    cc = open('{}'.format(filename),'r',encoding='{}'.format(scr_type))
    ccc = cc.read()
    cccc = ccc.encode('{}'.format(scr_type)).decode('gbk')
    cc.close()
    cc = open('{}'.format(filename),'w',encoding='{}'.format(obj_type))
    cc.write(cccc)
    cc.close()

if len(sys.argv) != 4:
    print("Usage:python" + sys.argv[0] + "/data/xx.txt iso8859-1 utf8")

if __name__ == '__main__':
    filename = sys.argv[1]
    scr_type = sys.argv[2]
    obj_type = sys.argv[3]
