python 自帶的ide 不能保存文件

初學python 用shell寫的代碼結果不能保存，經查詢，原因有人說是因為文件里有中文，

import random

secret =random.randint(1,100)
guess=0
tries=0

print "______"

while guess!=secret and tries<6:
    guess=input("what's you guess:")
    if guess<secret:
        print "low"
    elif guess>secret:
        print "too height"
    tries =tries+1
if guess==secret:
    print "you are lucky you right"
else:
    print "no chance,you lose"
    print "right secret:"+secret

 

改寫代碼全部用英文結果成功保存

的代碼中有中文，可能涉及到編碼問題，在代碼開頭加上#coding=utf-8

what's you guess:49
too height
what's you guess:24
low
what's you guess:36
low
what's you guess:42
low
what's you guess:46
low
what's you guess:48
too height
沒機會了你輸了

Traceback (most recent call last):
File "F:/work/py/startWithChild/1-2/GuessNumber.py", line 21, in <module>
print "right secret:"+secret
TypeError: cannot concatenate 'str' and 'int' objects

運行結果報錯，是說str類型不能和int類型直接拼接，解決方法 

最后一行代碼修改，用bytes() 將參數修改。

print "right secret:"+bytes(secret)
