I have a string array, for example:
a = ['123', '456', '789']
I want to split it to form a 2-dimension char array:
b = [['1', '2', '3'], ['4', '5', '6'], ['7', '8', '9']]
I'm using
[[element for element in line] for line in array]
to achieve my goal but found it not easy to read, is there any built-in function or any readable way to do it?
you could do something like:
first_list = ['123', '456', '789']
other_weirder_list = [list(line) for line in first_list]
Your solution isn't that bad, but you might do something like this or the map suggestion by arashajii.
map(list, array) should do it.
You can use map:
>>> a
['123', '456', '789']
>>> map(list, a)
[['1', '2', '3'], ['4', '5', '6'], ['7', '8', '9']]
Although I really don't see why you'd need to do this (unless you plan on editing one specific character in the string?). Strings behave similarly to lists.
First I tried e.split(''), but I get ValueError: empty separator.
Try this:
a = ['123', '456', '789']
b = [list(e) for e in a]
b
[['1', '2', '3'], ['4', '5', '6'], ['7', '8', '9']]
