How to remove WindowsPath and parantheses from a string [duplicate]

Closed 4 days ago.

I need to remove WindowsPath( and some of the closing parentheses ) from a directory string.

x= (WindowsPath('D:/test/1_birds_bp.png'),WindowsPath('D:/test/1_eagle_mp.png'))

What I need to have is

x= ('D:/test/1_birds_bp.png', 'D:/test/1_eagle_mp.png')

I don't know how to do multiple strings at once.

by following @MonkeyZeus I tried;

y = [re.sub("(?<=WindowsPath\(').*?(?='\))",'',a) for  a in x]

TypeError: expected string or bytes-like object

回答1:

You can easily target the paths with:

(?<=WindowsPath\(').*?(?='\))

• (?<=WindowsPath\(') - left side needs to literally be WindowsPath('
• .*? - lazily capture everything until we hit the positive lookahead
• (?='\)) - positive lookahead for literally ')

回答2:

x= "(WindowsPath('D:/test/1_birds_bp.png'),WindowsPath('D:/test/1_eagle_mp.png'))"

x.replace('WindowsPath(','').replace('(','').replace(')','')

output:

'D:/test/1_birds_bp.png','D:/test/1_eagle_mp.png'
