为了帮助我学习正则表达式，我试图改进那些写得不好的现有正则表达式。
阅读https://www.loggly.com/blog/five-invaluable-techniques-to-improve-regex-performance：
var formData = ['key' => value], than i get unexpected string
要自动执行查找性能较差的正则表达式的过程，我正在考虑编写一个脚本，该脚本将使用上述规则检查每个正则表达式。例如，搜索score=0
print("Welcome the the general knowledge quiz")
your_name = input("What is your name?: ")
input("Press Enter to Start the Quiz!")
print("1) Who presents Pointless?")
answer = input()
if answer == ["Alexander Armstong", "alexander armstrong", "ALEXANDER
ARMSTRONG"]:
print("Well done", your_name)
score = score+1
else:
print("Sorry, the answer was Alexander Armstrong")
print("Your score is", score)
print("2) Who presents I'm a celeb, get me out of here?")
answer = input()
if answer == ["Ant and Dec", "ant and dec", "ANT AND DEC", "Ant And Dec"]:
print("Well done", your_name)
score = score+1
else:
print("Sorry, the answer was Ant and Dec")
print("Your score is", score)
print("3) What is the capital of England?")
answer = input()
if answer == ["London", "london", "LONDON"]:
print("Well done", your_name)
score = score+1
else:
print("Sorry, the answer was London")
print("Your score is", score)
print("4) Who lives on the White house right now?")
answer = input()
if answer == ["Obama", "obama", "Barack Obama", "barack obama"]:
print("Well done", your_name)
score = score+1
else:
print("Sorry, the answer was Barack Obama")
print("Your score is", score)
以检查每个正则表达式中的字符类。如果正则表达式不包含字符类，那么它可能是性能优化的候选者。
我是否可以使用其他基于规则的方法来检查正则表达式的性能。
或许也许有一个Java / Python库目前正在实现这个功能？
