How to create a two dimensional array in python












-3















How to create a two dimensional array in python. Specifically by initiating it with an existing array for the first index.



I have an array:



x = [1.0, 2.0, 3.0]


and I want to create a new one from it:



y = [[1.0, 2.0, 3.0]]


How can I convert x to y



I am using Python 3.

>>> x = [1.0, 2.0, 3.0]


You want to put x in a list, to get [x]. Hmm...



>>> y = [x]

>>> y

[[1.0, 2.0, 3.0]]


Yay!




In Python, it's best to try the obvious approach first. To quote the Zen of Python:




There should be one-- and preferably only one --obvious way to do it.

Although that way may not be obvious at first unless you're Dutch.

A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México
