converting an array of arrays of floats to complex numbers

Question

I've got an list of lists each containing the two parts of a complex number, like this:

parts = [[1, 2], [3, 4], [5, 6]]

How do I convert them to a list of complex numbers, like this?

munged = [1+2i, 3+4i, 5+6i]

Answer 1

This should work

parts = [[1, 2], [3, 4], [5, 6]]

complex_list = [complex(*x) for x in parts]

[(1+2j), (3+4j), (5+6j)]

Note: Each complex number will be a complex object (1+2j). If you need it to be a string '1+2j' or '1+2i'; use:

# f"{a}+{b}j" or f"{a}+{b}i"
complex_list = [f"{a}+{b}i" for a, b in parts]

['1+2i', '3+4i', '5+6i']
