Add tuple to a list of tuples
python
Solution
one-liner using nested list comprehensions and the magic `zip` to interleave the fixed `b` triplet to add to the iterating element of `a`, no numpy needed:
a = [(0, 1, 2), (3, 4, 5), (6, 7, 8)]
b = (10, 20, 30)
c = [tuple([i+j for i,j in zip(e,b)]) for e in a]
print(c)
result:
[(10, 21, 32), (13, 24, 35), (16, 27, 38)]
EDIT: you could drop the `tuple` conversion if not needed:
c = [[i+j for i,j in zip(e,b)] for e in a]
Problem
How can I sum a tuple to a list of tuples such as: ``` >>> a = [(0, 1, 2), (3, 4, 5), (6, 7, 8)] >>> b = (10, 20, 30) ``` the result being: ``` >>> c [(10, 21, 32), (13, 24, 35), (16, 27, 38)] ``` I know this can be easily solved with numpy: ``` >>> import numpy >>> c = numpy.add(a, b).tolist() >>> c [[10, 21, 32], [13, 24, 35], [16, 27, 38]] ``` but I'd rather avoid numpy.
