Solve these subtasks all in the same file (use print() statements to display the results):

Use the following list:

sample = ["a", 90, 8, "X55", "1z", 102, "asdf", 65, 10, "word", "567", 567]

Well:

• Print the sorted list (you might need to return to this later and make it right :P);
• Filter out all non-numbers in the list (note: those values of the int type should remain!)… can you make it using a single line of code? now it's the time to introduce list comprehensions;
• Print the original list (remember the sort? read this answer!);
• Define a function that builds a matrix filled with numbers from 1 to n like the following example:

  m = [[1, 2, 3, 4],
       [4, 1, 2, 3],
       [3, 4, 1, 2],
       [2, 3, 4, 1]]
