如何使python代码更简单

Question

i have following python code. Can i optimise it to one line:

url = request.session.get('my_value', '/')
    if url == '/None/':
        url = '/'

Any help will be appericiated

Answer 1

url = re.sub("^/None/$","/",request.session.get('my_value', '/'))

Answer 2

I think this should work:

url = [request.session.get('my_value', '/'), '/']['/None/' in request.session.get('my_value', '/')]

But honestly, it makes the code much more horrible to read...

Answer 3

url = '/' if url == '/None/': else url = request.session.get ('my_value', '/')
