Can I put a tuple into an array in python?
One thing to keep in mind is that a tuple is immutable. This means that once it's created, you can't modify it in-place. A list, on the other hand, is mutable -- meaning you can add elements, remove elements, and change elements in-place. A list has extra overhead, so only use a list if you need to modify the values.
You can create a list of tuples:
>>> list_of_tuples = [(1,2),(3,4)]>>> list_of_tuples[(1, 2), (3, 4)]
or a list of lists:
>>> list_of_lists = [[1, 2], [3, 4]]>>> list_of_lists[[1, 2], [3, 4]]
The difference is that you can modify the elements in the list of lists:
>>> list_of_lists[0][0] = 7>>> list_of_lists[[7, 2], [3, 4]]
but not with the list of tuples:
>>> list_of_tuples[0][0] = 7Traceback (most recent call last): File "<stdin>", line 1, in <module>TypeError: 'tuple' object does not support item assignment
To iterate over a list of tuples:
>>> for (x,y) in list_of_tuples:... print x,y... 1 23 4
