I want to be sure that none item of a list is present on a string.
At the moment I do :
presents = False
for item in item_list:
if item in string_control:
presents = True
break;
Is there a way to do it in only one line ? I really often do these types of control.

Yes :
presents = any(x in string_control for x in item_list)

I think string_control
has a value something like this. presents
then becomes a boolean indicating the same as in your code but most likely in most circumstances you don't need the cast to bool. I.e. this probably works fine too: presents = [i for i in item_list if i == string_control]
string_control = None
presents = bool([i for i in item_list if i == string_control])
