I am getting this: {{{{{{1, 1}}, {2, 4}}, {3, 9}}, {4, 16}}, {5, 25}}

I want it like this: {{1, 1}, {2, 4}, {3, 9}, {4, 16}, {5, 25}} so that I can use this as coordinate points in ListPlot to make a plot.

I tried using Flatten (it removes all the inner brackets so that it stops being a coordinate) , First etc but nothing worked. Please help

  • $\begingroup$ Thank you. As of now, using cvgmt's method works perfectly fine. I will check the link out, nonetheless. $\endgroup$

    $\begingroup$ A simple method is to Flatten as you suggested but then to Partition into sublists of 2. This should work: Partition[Flatten[list],2] $\endgroup$

$\begingroup$ 
list= {{{{{{1, 1}}, {2, 4}}, {3, 9}}, {4, 16}}, {5, 25}};
Level[list, {-2}]

We can using TreeForm to understand the method.

list= {{{{{{1, 1}}, {2, 4}}, {3, 9}}, {4, 16}}, {5, 25}};
TreeForm[list]

  • $\begingroup$ Just a note that while this code solves this particular problem, it is not a general solution, since it only works for atomic list elements (numbers in this case). $\endgroup$
