Python list comprehension, unpacking and multiple operations
Use a nested list comprehension:
result = [a for tup in y for a in tup]Example:
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]
