Symmetric Matrix

A matrix is symmetric if the first row is the same as the first column, the second row is the same as the second column etc… Write a function to determine whether a matrix is symmetric.

Example input and output:

print symmetric([[1, 2, 3],
                [2, 3, 4],
                [3, 4, 1]])
>>> True

print symmetric([["cat", "dog", "fish"],
               ["dog", "dog", "fish"],
               ["fish", "fish", "cat"]])
>>> True
