[Python Challenge] - Q2

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

提示說，可能在網頁源文件中，打開源文件，可以看到一大堆“}@[@%]()%+$&[(_@%+%$*^@$^!+”之類的註釋。同時上面還有一行註釋說find rare characters in the mess below, 就是要找那一大堆註釋中比較稀少的字符。

 

PS：我將註釋保存到文件“src”中。

 

代碼：

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

正確答案是“equality”，將網頁中的ocr替換即可。
