If I have a list of tuples a = [(1,2), (3,4), (5,6)], and I want to return a new list of each individual element in these tuples, I can do it with a nested for loop but when I try to do it using the list comprehension b = [j for j in i for i in a], my output is b = [5,5,5,6,6,6] instead of the correct b = [1,2,3,4,5,6]. What am I doing wrong? -- http://mail.python.org/mailman/listinfo/python-list
>>> a = [(1,2), (3,4), (5,6)] >>> [i for t in a for i in t] [1, 2, 3, 4, 5, 6] Or, with different spacing to make the nesting clearer: >>> [i ... for t in a ... for i in t] [1, 2, 3, 4, 5, 6] >>> Michael -- http://mail.python.org/mailman/listinfo/python-list
