[Python Challenge] - Q2

Q2：PC----ocr recognize the characters. maybe they are in the book, but MAYBE they are in the page source.

提示说，可能在网页源文件中，打开源文件，可以看到一大堆“}@[@%]()%+$&[(_@%+%$*^@$^!+”之类的注释。同时上面还有一行注释说find rare characters in the mess below, 就是要找那一大堆注释中比较稀少的字符。

 

PS：我将注释保存到文件“src”中。

 

代码：

file = open ("src")lines = file.readlines()dict = {}key_index = []for line in lines: for i in line: if dict.has_key(i): tmp = dict[i] dict[i] = tmp + 1 else : dict[i] = 1 key_index.append(i)for key in key_index: if dict[key] < 15: print key

正确答案是“equality”，将网页中的ocr替换即可。
