[Tutor] correlation matrix

[Beanan O Loughlin]

hi all,

I am new to python, and indeed to programming, but i have a question 
regarding correlation matrices.

If i have a column vector

x=[1;2;3;4;5]

and its transpose row vector

xt=[1,2,3,4,5]

is there a simple way in python to create a 5x5 correlation matrix, 
obviously symmetric and having 1's on the diagonal?

Thank you very much in advance,

B.
