混合大写单词和符号的最佳正则表达式是什么？
What is the best regex for a mix of capitalised words and symbols?
我正在尝试组织以下列表：
list of gaming genre
我想将连接的单词分开，但它们似乎不会正确使用代表首字母缩略词（例如 PVP、MMORPG、MOBA、DeFi）的大写单词。
目前，我的正则表达式代码如下：
re.sub(r"(\w)([A-Z])", r" ", ele) for ele in genre_list
正如您在下面看到的，它有时有效，有时无效：
['Collectible Open-World Virtual-World', 'Breeding Card PV P', 'Auto-Battler Breeding Strategy', 'Minigame Open-World Virtual-World', 'Action Simulation Sports', 'Adventure MM OStrategy', 'Adventure Casual Puzzle', 'Sports', 'Collectible Sci-Fi Virtual-World', 'Battle-Royalee Sports MO BA', 'Action PV PShooter', 'P VP Sci-Fi Tower-Defense', 'Action Battle-Royale', 'P VP Sci-Fi Shooter', 'Breeding Collectible Mining', 'Collectible De Fie Sports', 'Action Adventure Shooter', 'City-Building Collectible Simulation', 'Action Strategy', 'Adventure Open-World', 'Breeding Racing Sports', 'Open-World Virtual-World', 'Collectible Idle', 'Action Adventure', 'Card Collectible PV P', 'Battle-Royale Fantasy MO BA', 'City-Building', 'Building MM OStrategy', 'Adventure MM OR PG', 'Action Adventure Idle', 'M OB AR PG Strategy', 'M MO RP GStrategy', 'Card Collectible Idle', 'Open-World PV PR PG', 'De Fi MM OSpace', 'Collectible', 'Card Collectible PV P', 'Auto-Battler De Fi RP G', 'Adventure MM OOpen-World', 'Collectible Open-World Virtual-World', 'Collectible Idle RP G', 'Card Collectible PV P', 'Action Adventure PV P', 'Sci-Fi Shooter Survival', 'Action Strategy', 'Arcade Minigame', 'Breeding PV PRacing', 'M OB AP VP', 'Action Sports', 'P VP Space Turn-based', 'M MO Strategy Tower-Defense']
你能帮我看看哪个正则表达式最适合这个吗？或者正则表达式不适用于此列表？谢谢！
根据评论进行编辑：
您只需要在 [A-Z] 之后添加一个“+”，即 r"(\w)([A-Z]+)"。
这将匹配 1 个或多个大写字母。
这很困难，因为您有可能会粘在一起的全大写单词。如果你有这样的列表，它是可以解决的。
您可以使用和增强以下代码以获得更好的输出精度：
import re
l = ['Collectible Open-World Virtual-World', 'Breeding Card PV P', 'Auto-Battler Breeding Strategy', 'Minigame Open-World Virtual-World', 'Action Simulation Sports', 'Adventure MM OStrategy', 'Adventure Casual Puzzle', 'Sports', 'Collectible Sci-Fi Virtual-World', 'Battle-Royalee Sports MO BA', 'Action PV PShooter', 'P VP Sci-Fi Tower-Defense', 'Action Battle-Royale', 'P VP Sci-Fi Shooter', 'Breeding Collectible Mining', 'Collectible De Fie Sports', 'Action Adventure Shooter', 'City-Building Collectible Simulation', 'Action Strategy', 'Adventure Open-World', 'Breeding Racing Sports', 'Open-World Virtual-World', 'Collectible Idle', 'Action Adventure', 'Card Collectible PV P', 'Battle-Royale Fantasy MO BA', 'City-Building', 'Building MM OStrategy', 'Adventure MM OR PG', 'Action Adventure Idle', 'M OB AR PG Strategy', 'M MO RP GStrategy', 'Card Collectible Idle', 'Open-World PV PR PG', 'De Fi MM OSpace', 'Collectible', 'Card Collectible PV P', 'Auto-Battler De Fi RP G', 'Adventure MM OOpen-World', 'Collectible Open-World Virtual-World', 'Collectible Idle RP G', 'Card Collectible PV P', 'Action Adventure PV P', 'Sci-Fi Shooter Survival', 'Action Strategy', 'Arcade Minigame', 'Breeding PV PRacing', 'M OB AP VP', 'Action Sports', 'P VP Space Turn-based', 'M MO Strategy Tower-Defense']
l = [''.join(s.split()) for s in l]
allcaps = ['RPG', 'MOBA', 'PVP', 'MMO']
rx_1 = re.compile(r'[a-z](?=[A-Z])|[A-Z](?=[A-Z][a-z])')
rx_2 = re.compile( fr"\b(?:{r'|'.join(allcaps)})(?=[A-Za-z])" )
rx_3 = re.compile( fr"(?<=[A-Za-z])(?:{r'|'.join(allcaps)})\b" )
for s in l:
print( r'{} => {}'.format(s, rx_3.sub(r" \g<0>", rx_2.sub(r"\g<0> ", rx_1.sub(r"\g<0> ", s)))) )

[a-z](?=[A-Z])|[A-Z](?=[A-Z][a-z]) 正则表达式（参见 its demo）匹配
[a-z](?=[A-Z]) - 紧跟大写字母的小写字母| - 或[A-Z](?=[A-Z][a-z]) - 一个大写字母后跟一个大写字母和一个小写字母。
我们在这些匹配后添加 space。
rx_2 和 rx_3 正则表达式是根据 ALLCAPS 单词列表构建的，并在左侧或右侧添加 space，具体取决于另一个字母出现在哪一侧。
