python - Is there any way to return value in list comprehension? -

i wonder if can return value in list comprehension like

[return role_ role_ in self.roles if role.name==parameter]

of course doesn't work. @ moment had use classic loop

for role_ in self.roles:     if role_.name == parameter:         return role_

use next() function generator expression:

return next((role_ role_ in self.roles if role_.name == parameter), none)

this return first matching role_ value, or none if there no such value.

you can't use list comprehension, no, because not producing list.
