00364.txt with 28 words in 0m0.927s
00366.txt with 105 words in 0m2.422s
00367.txt with 168 words in 0m3.292s
00368.txt with 1515 words in 0m27.238

应该打印如下：

00364.txt with   28 words in 0m0.927s
00366.txt with  105 words in 0m2.422s
00367.txt with  168 words in 0m3.292s
00368.txt with 1515 words in 0m27.238

我从一个for循环中逐行打印出来。我会知道一个文件中的单词数量的上限(现在不是这样)。
