Python list comprehension, unpacking and multiple operations
Use a nested list comprehension:
result = [a for tup in y for a in tup]Example:
>>> x = range(10)>>> y = [(i,j**2) for i,j in zip(x,x)]>>> [a for tup in y for a in tup][0, 0, 1, 1, 2, 4, 3, 9, 4, 16, 5, 25, 6, 36, 7, 49, 8, 64, 9, 81]This will work fine for your more general case as well, or you could do it all in one step:
y = [a for i in x for a in (i, sqrt(i), i**3, some_operation_on_i, f(i), g(i))]In case the nested list comprehensions look odd, here is how this would look as a normal for loop:
y = []for i in x: for a in (i, sqrt(i), i**3, some_operation_on_i, f(i), g(i)): y.append(a)
>>> import itertools>>> list(itertools.chain.from_iterable(y))[0, 0, 1, 1, 2, 4, 3, 9, 4, 16, 5, 25, 6, 36, 7, 49, 8, 64, 9, 81]
