“＃hash”对IDLE有什么意义吗？ [英] Does '#hash' mean anything in IDLE?
问题描述
问候，
我目前正试图通过优秀的学习Python来学习Python。学习Python书。我写了我的第一个非平凡的程序，
从几个注释行开始。其中一条注释行以
''＃hash''开头。 IDLE并没有将它作为注释行着色，而是用紫色代替'b b'这个单词''hash''，就好像它是一个关键词。奇怪的。行为
似乎很容易触发：只需在IDLE中打开一个新窗口并输入
这两行：
＃这是一个测试
#hash应该仍然是一个评论行
然后，保存后，第二行没有着色为评论行
虽然第一个是。
这是一个错误，还是以#hash开头的注释行有一些
的特殊含义？
我的程序运行正常，所以似乎解释器本身是
忽略了这条线。

这不仅仅是#hash，还有像#dict，＃n，＃在
评论开头的评论这条线击败了IDLE的着色算法。
有趣的是，＃while或#for之类的行为符合预期，所以它好像b $ b似乎是内置的而不是关键词是问题。要回答我自己的问题 - 这显然是一个（无害的）错误。

我也是！

到目前为止你觉得Python怎么样？我最喜欢字典对象所以
远。我是从VBScript来到Python的，所以我已经知道了这些东西的价值，但在Python中它们得到了更好的支持。
这是我正在谈论的程序，*真的*显示了功能

#Python程序用大多数单字字谜发现单词
＃以下哈希函数有属性

def letter_hash（word）：
代码= 26 * [0]

return_string =''''
for i in range（26）：
j = codes [i]
如果j> 0：

返回return_string

" yawl"代表又一个单词列表。这是一些文本列表，其中包括一些英语单词，包括各种古老和技术性的b $ b短语。 Google foryawl word list如果你想追查一份副本。
输出是
[''apers''，''apres''，''asper'' ，''削减''，''解析''，''梨''，''prase''，
''presa''，''强奸''，''收获'' ，''spaer''，''spare''，''spear'']
这13个单词是彼此的字谜。它们包含一些漂亮的
晦涩难懂的单词：asper是一个17世纪的土耳其硬币，而spaer是一个古老的苏格兰方言单词，供先知使用（你可以看到发言者）。

Greetings,
I am currently trying to learn Python through the excellent
"Learning Python" book. I wrote my first non-trivial program, which
began with several comment lines. One of the comment lines began with
''#hash''. IDLE doesn''t colorize it as a comment line but instead colors
the word ''hash'' in purple as if it were a key word. Wierd. The behavior
seems easy to trigger: Just open up a new window in IDLE and enter
these two lines:
#This is a test
#hash should still be a comment line
Then, after saving, the second line is not colored as a comment line
though the first is.
Is this a bug, or do comment lines which begin with #hash have some
special meaning?
My program ran fine, so it seems that the interpreter itself is
ignoring the line.

It isn''t just #hash, but also things like #dict, #int, #len at the
start of a comment line which defeats IDLE''s colorization algorithm.
Interestingly, things like #while or #for behave as expected so it
seems to be built-ins rather than keywords which are the problem. To
answer my own question - this is pretty clearly a (harmless) bug.

How do you like Python so far? I like dictionary objects the best so
far. I''m coming to Python from VBScript, so I already knew the value of
such things, but in Python they are better supported.
Here is the program I was talking about, which *really* shows the power
of dictionaries:
************************************************** ***************************************
#Python program to discover word with most 1-word anagrams
#The following hash function has the property
#that words which are anagrams of each other
#hash to the same string. It assumes that input
#is lower case in range ''a'' to ''z''
def letter_hash(word):
codes = 26 * [0]
for c in word:
codes[ord(c)-97] +=1
return_string = ''''
for i in range(26):
j = codes[i]
if j > 0:
return_string += (str(j)+chr(i+97))
return return_string
#main program:
hashes = {}
#first load dictionary of hashes
for line in open(''C:\\yawl.txt'').readlines():
word = line.strip().lower() #to be safe
my_hash = letter_hash(word)
hashes.setdefault(my_hash,[]).append(word)
#now find word with most anagrams
max_len = 0
max_words = []
for word_list in hashes.itervalues():
if len(word_list) > max_len:
max_len = len(word_list)
max_words = word_list
print max_words
************************************************** ********
"yawl" stands for "Yet Another Word List". It is a text-list of some
240,000 English words, including all sorts of archaic and technical
phrases. Google for "yawl word list" if you want to track down a copy.
The output is
[''apers'', ''apres'', ''asper'', ''pares'', ''parse'', ''pears'', ''prase'',
''presa'', ''rapes'', ''reaps'', ''spaer'', ''spare'', ''spear'']
These 13 words are anagrams of each other. They contain some pretty
obscure words: asper is a 17th century Turkish coin and spaer is an
archaic Scottish-dialect word word for prophet (you can see "speaker"
if you squint).
