Python: Find in list

Question

I have come across this:

item = someSortOfSelection() 

if item in myList: 

doMySpecialFunction(item)

but sometimes it does not work with all my items, as if they weren't recognized in the list (when it's a list of string).

Is this the most 'pythonic' way of finding an item in a list: if x in l:?

Answer 1

To find one element or None use default in next, it will not raise StopIteration if the item was not found in the list:

first_or_default = next((x for x in lst if ...), None)
