I have a list like below where the first element is the id and the other is a string:
[(1, u'abc'), (2, u'def')]
I want to create a list of ids only from this list of tuples as below:
[1,2]
I’ll use this list in __in
so it needs to be a list of integer values.

>>> a = [(1, u'abc'), (2, u'def')] >>> [i[0] for i in a] [1, 2]
