Creating acronyms in Python
提问by user225312
In Python, how do I make an acronym of a given string?
在 Python 中，如何制作给定字符串的首字母缩略词？
Like, input string:
比如，输入字符串：
'First Second Third'
Output:
输出：
'FST'
I am trying something like:
我正在尝试类似的东西：
>>> for e in x:
print e[0]
But it is not working... Any suggestions on how this can be done? I am sure there is a proper way of doing this but I can't seem to figure it out. Do I have to use re?
但它不起作用......关于如何做到这一点的任何建议？我确信有一种正确的方法可以做到这一点，但我似乎无法弄清楚。我必须使用re吗？

Try
尝试
print "".join(e[0] for e in x.split())
Your loop actually loops over all characters in the string x. If you would like to loop over the words, you can use x.split().
您的循环实际上会遍历 string 中的所有字符x。如果您想遍历单词，可以使用x.split().

Without re:
没有re：
>>> names = 'Vincent Vega Jules Winnfield'
>>> ''.join(x[0] for x in names.split())
'VVJW'

s = 'First Second Third'
x = s.split(' ')
for e in x:
print e[0]
should do the trick.
应该做的伎俩。

Also you could use
你也可以使用
re.split('\W')
re.split('\W')
to split the line/text on non-word characters. This might be a little bit more robust.
在非单词字符上拆分行/文本。这可能会更健壮一点。

If you want to use capitals only
如果您只想使用大写字母
>>>line = ' What AboutMe '
>>>filter(str.isupper, line)
'WAM'
What about words that may not be Leading Caps.
那些可能不是大写字母的单词呢？
>>>line = ' What is Up '
>>>''.join(w[0].upper() for w in line.split())
'WIU'
What about only the Caps words.
只有 Caps 字样怎么办。
>>>line = ' GNU is Not Unix '
>>>''.join(w[0] for w in line.split() if w[0].isupper())
'GNU'
回答by Rafe Kettler
If you want to do things the way that is grammatically correct (regardless of locale), use title(), then filter():
如果您想以语法正确的方式（无论语言环境如何）做事，请使用title()，然后filter()：
acronym = filter(str.isupper, my_string.title())
title()is pretty awesome; it makes a string titlecased and is correct according to locale.
title()非常棒；它使字符串标题化并且根据语言环境是正确的。

Here's how to do acronym with regular expression, leaving numbers as is:
以下是如何使用正则表达式进行首字母缩略词，保留数字原样：
import re
words = "internet explorer 10"
print re.sub(r"([a-zA-Z])[a-z,A-Z]+\s*",r"",words).upper()
IE10
IE10
