Input is shown below (my_list). This is actually list of hexadecimal numbers. Every pair of elements 0-1, 2-3, 4-5 form 16-bit signed integers, hence I need to merge every pair of elements.
my_list = [['61', '00', '7B', '01', 'F2', '1F'],
['9A', 'FE', '8C', '02', '01', '22'],
['F4', 'FD', '60', '04', '35', '24']]
The output I would like to get is
aX = ['6100', '9AFE', 'F4FD']
aY = ['7B01', '8C02', '6004']
aZ = ['F21F', '0122', '3524']
Right now I am doing it the following way. It works, but the issue is I have to keep adding more lines of code as the row length of my_list increases. Is there a better way?
aX = [ x[0] + x[1] for x in my_list ]
aY = [ x[2] + x[3] for x in my_list ]
aZ = [ x[4] + x[5] for x in my_list ]
Appreciate your inputs!
>Solution :
You can combine map, zip like below:
>>> list(zip(*map(lambda x: [''.join(x[i:i+2]) for i in range(0, len(x), 2)], my_list)))
[('6100', '9AFE', 'F4FD'), ('7B01', '8C02', '6004'), ('F21F', '0122', '3524')]
Or as a nested list:
>>> list(map(list, zip(*map(lambda x: [''.join(x[i:i+2]) for i in range(0, len(x), 2)], my_list))))
[['6100', '9AFE', 'F4FD'], ['7B01', '8C02', '6004'], ['F21F', '0122', '3524']]
