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 its created, you cant 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] = 7
Traceback (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 2
3 4

if you are talking about list, you can put anything into it, even different types:


l[0] = (1,2,3)
l.extend((21,22)) #this one adds each element from the tuple

if you mean array, no python arrays dont support tuples.

a = [ (b, i , ff ) for i in range(1,5)]
