python2.7 print 中文乱码

python最开始这行加了

-*- coding: utf-8

并且print("你好"),是可以打印出来的。

chn_tab = ["啊","阿"]

rec = ""
for predict_label in pos:
    if predict_label != blank_label and predict_label != prev_label:
        rec += chn_tab[predict_label]
        prev_label = predict_label
print(rec)
print("rec=", rec)
print('rec={}'.format(rec))

车牌号码
('rec=', '\xe8\xbd\xa6\xe7\x89\x8c\xe5\x8f\xb7\xe7\xa0\x81')
rec=车牌号码

搞不懂为啥我就print("rec=", rec)这样子就是输出乱码了呢？
