Regular expression: match (aa | bb) (cc)?

Question

My regex should be able to find strings:

• Visual studio 2008
• Visual Studio Express 2008
• Visual basic 2008
• Visual Basic Express 2008
• Visual C ++ 2008
• Visual C ++ Express 2008

and many other similar options that should be replaced with one single line

Visual studio 2005

I tried "Visual (Basic | C ++ | Studio) (Express)? 2008", but it does not work. Any ideas?

Edit : Now I tried "Visual (Basic) | (C ++) | (Studio) (Express)? 2008", but the replaced line becomes "Visual Studio 2005 Express 2008" to enter "Visual Basic Express 2008".

Answer 1

It should be

"Visual (Basic|C\+\+|Studio)( Express)? 2008"

>>> import re
>>> repl = 'Visual Studio 2005'
>>> regexp = re.compile('Visual (Studio|Basic|C\+\+)( Express)? 2008')
>>> test1 = 'Visual Studio 2008'
>>> test2 = 'Visual Studio Express 2008'
>>> test3 = 'Visual C++ Express 2008'
>>> test4 = 'Visual C++ Express 1008'
>>> re.sub(regexp,repl,test1)
'Visual Studio 2005'
>>> re.sub(regexp,repl,test2)
'Visual Studio 2005'
>>> re.sub(regexp,repl,test3)
'Visual Studio 2005'
>>> re.sub(regexp,repl,test4)
'Visual C++ Express 1008'
