How can I turn a list into an array in python?
How can I turn a list such as:
data_list = [0,1,2,3,4,5,6,7,8] into a list of lists such as:
new_list = [ [0,1,2] , [3,4,5] , [6,7,8] ] ie I want to group ordered elements in a list and keep them in an ordered list. How can I do this?
Thanks

We can also use the python module names abstract syntax trees or called ast. It has a function named literal_eval which will keep the elements of the given list together and convert it to a new list.
Thus, converting the whole list into a list of lists. Use another list 'res' and a for a loop. Using split() method of Python we extract each element from the list in the form of the list itself and append it to 'res'. Finally, return 'res'.
Correct: <ul> as child of <li> The proper way to make HTML nested list is with the nested <ul> as a child of the <li> to which it belongs. The nested list should be inside of the <li> element of the list in which it is nested.
This groups each 3 elements in the order they appear:
new_list = [data_list[i:i+3] for i in range(0, len(data_list), 3)] Give us a better example if it is not what you want.

This assumes that data_list has a length that is a multiple of three
i=0 new_list=[] while i<len(data_list): new_list.append(data_list[i:i+3]) i+=3 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
