无法打印已转换为字符串的整数(Can't print an integer that has been converted to a string)

 我正在尝试做一些应该很简单的事情。 我有点沮丧，为什么我的代码无法正常工作，所以任何帮助表示赞赏:)。 
 
 我的程序读入数据，然后创建一个记录特定项目出现次数的字典（我正在使用Twitter数据并计算hashtag出现次数）。 我想输出最热门的推文，并找到了一个很好的简单方法来实现这一点，使用以下内容： 
 
def main():
    tweet_file = open(sys.argv[1])
    tweet_dic = lines(tweet_file) #function that makes my dictionary
    for i in range(0,10):
        big_key = max(tweet_dic, key = lambda i: tweet_dic[i])
        big_value = tweet_dic[big_key]
        sys.stdout = big_key + " " + str(big_value)
        del tweet_dic["big_key"]
    tweet_file.close()
 
 我得到的错误是AttributeError: 'str' object has no attribute 'write' 
 
 现在我已经使用print输出了两个不同的值到终端使用print就好了，它们可以放在两个不同的print语句，没有问题，因为我不必连接或任何东西。 我已经检查了两个变量类型，并且如预期的那样，它们始终是str ＆ int 。 
 
 我对str （整数转换）函数的理解是，你应该能够传递一个整数并获得一个字符串表示！ 转换完成后，我可以在过去没有任何问题的情况下打印出类似的内容。 
 
 需要考虑的事情可能会被抛出 - big_key有时可能是一个string ，它通过.encode('utf-8')从Unicode转换而来。 否则，我的文件输出（单独打印）如下所示： 
 
MTVHottest 60

KCAMexico 38

EXO 26

CD9 24

Unicode 19

Coders 18

AlonsoVillapandoTrendy 17

 有任何想法吗？ 提前致谢！ 

I am trying to do something that should be very simple. I am a bit frustrated for why my code won't work, so any help is appreciated :).
 
My program reads in data, and then makes a dictionary that records the number of times a particular item occurs (I am using Twitter data and counting hashtag occurrences). I want to output the top tweets, and have found a nice easy way to do that using the following:
 
def main():
    tweet_file = open(sys.argv[1])
    tweet_dic = lines(tweet_file) #function that makes my dictionary
    for i in range(0,10):
        big_key = max(tweet_dic, key = lambda i: tweet_dic[i])
        big_value = tweet_dic[big_key]
        sys.stdout = big_key + " " + str(big_value)
        del tweet_dic["big_key"]
    tweet_file.close()
 
The error I get on using this is AttributeError: 'str' object has no attribute 'write'
 
Now I have outputted the two different values into terminal using print just fine, they can be put in two different print statements with no problems since I don't have to concatenate or anything. I have checked the two variables types, and as expected they are always str & int.
 
My understanding of the str(integer to convert) function is that you should be able to pass in an integer and get a string representation back! After it has been converted, I have been able to print out things like this in the past with no issues.
 
Things to consider that may be throwing it out - the big_key can sometimes be a string that was converted from Unicode by .encode('utf-8'). Otherwise the output from my file (printing on separate lines) looks like:
 
MTVHottest 60

KCAMexico 38

EXO 26

CD9 24

Coders 18

Any ideas? Thanks in advance!
