a = [1,2,3]
b = [4,5,6]
I'm not asking about the easy merging of array like c = a+b
(which would yield [1,2,3,4,5,6]
.
What I am looking for is to join the contents of two arrays, so that the end-result would be as the following (given a
and b
written previously).
c = what-do-I-write-here? # [14,25,36]
How do I solve this?
You can zip
together your two lists, forming a new lists that will contain two-element tuples (pairs), where each pair consists of the elements at the corresponding index, from the two lists.
Python 3.5.0 (default, Sep 20 2015, 11:28:25)
[GCC 5.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> a = [1, 2, 3]
>>> b = [4, 5, 6]
>>> list (zip (a,b))
[(1, 4), (2, 5), (3, 6)]
This in turn will make it very easy to iterate over each pair, and create a new list with the desired contents.
In your question you have written that the result should be [14,25,36]
— implying that you are looking to concatenate the elements lexiographically, but then have the result still be ints.
You could solve it in a easy manner using code such as;
a = [1, 2, 3]
b = [4, 5, 6]
c = [ int(''.join (map (str, xs))) for xs in zip (a,b) ]
c is now [14, 25, 36]
