一个非常敏感的搜索 [英] a -very- case sensitive search
问题描述
我对Python很陌生，我想创建一个脚本，搜索
以下选项：
1）由大写字母组成的单词-only-（如YES）
2）由小写字母组成的单词-only-（如yes）
3）和只有第一个字母大写的单词（如是）
*我需要做所有这些考虑到并非所有字母确实都是确实英文字母。
我经历了不同的文档部分，但无法找到合适的
条件，功能或方法。
建议将非常贴切...

你好
*考虑到并非所有字母
都是英文字母，我需要做所有这些。
你的意思是英文字母（来自拉丁文/罗马文
字母表，fyi）？我很抱歉挑剔，但''英文字母''
对我来说听起来有点尴尬。
我经历了不同的文档部分，但是找不到合适的
条件，功能或方法。
建议非常适合...
我自己还在（试图）学习它，但你可以尝试使用正则表达式查看
。它有一个标准模块（重新），详见PyLib参考文件
; http://docs.python.org/lib/module-re。 HTML 。

我不确定你的意思是考虑到不是所有字母都是英文字母的事实;你可能意味着你不在乎关于非英语角色的b $ b，或者你可能意味着你根本不需要任何
非英语字符（所以函数应该在
中返回False（例如）。如果案例是前者，那么每个案例都有一个简单的测试：
> > word =''hi''
word.upper（）== word＃计算结果为True如果单词全部为大写
False
>> word.lower（）== word ＃如果单词全部小写，则计算结果为
True
>> word.title（）== word＃计算结果为True，如果单词是标题格式
False
> >>

我对Python很陌生，我想创建一个脚本来搜索
以下选项：
1）由大写字母组成的单词-only-（如YES）

条件，函数或方法为了它。
在命令提示符下：
>> dir（''''）
＃结果编辑为清晰
[...''isalnum''，''isalpha''，''isdigit''，''islower''，
''isspace''，''istitle ''，''isupper''，......]
然后执行此操作：
< blockquote class =post_quotes>
>> help（''''。islower）
and read它提供的文字。然后在命令行上进行实验：
>>''abcd1234''。islower （）
True
>>''aBcd1234''.lowlower（）
False
如果他们不合适，请回复我们，并告诉我们为什么他们不适合

Hi,
I am pretty new to Python and I want to make a script that will search
for the following options:
1) words made of uppercase characters -only- (like "YES")
2) words made of lowercase character -only- (like "yes")
3) and words with only the first letter capitalized (like "Yes")
* and I need to do all these considering the fact that not all letters
are indeed English letters.
I went through different documention section but couldn''t find a right
condition, function or method for it.
Suggestions will be very much appriciated...

Hi
* and I need to do all these considering the fact that not all letters
are indeed English letters.You mean letters from the English alphabet (derived from the Latin/Roman
alphabet, fyi)? I''m sorry for the nitpicking, but ''English letters''
sounds a bit too ''ackward'' to me.
I went through different documention section but couldn''t find a right
condition, function or method for it.
Suggestions will be very much appriciated...I''m still (trying to) learn(ing) it myself, but you can try looking into
using regular expressions. There''s a standard module for it (re), see
the PyLib Reference for details; http://docs.python.org/lib/module-re.html.

--OlaI''m not sure exactly what you mean by "considering the fact that not
all letters are indeed English letters"; you could mean you don''t care
about the non-english characters, or you could mean you don''t want any
non-english characters at all (so the function should return False in
that case). If the case is the former, there''s a simple test for each:
>>word = ''hi''
word.upper() == word # evaluates to True if the word is all caps
False
>>word.lower() == word # evaluates to True if the word is all lowercase
True
>>word.title() == word # evaluates to True if the word is in a title format
False

I went through different documention section but couldn''t find a right
condition, function or method for it.At the command prompt:
>>dir('''')
# result edited for clarity
[ ... ''isalnum'', ''isalpha'', ''isdigit'', ''islower'',
''isspace'', ''istitle'', ''isupper'', ... ]
Then do this:
>>help(''''.islower)
and read the text it provides. Then experiment on the command line:
>>''abcd1234''.islower()
True
>>''aBcd1234''.islower()
False
Then come back to us if they aren''t suitable, and tell us WHY they aren''t
suitable.
