[Tutor] list problem

[W.W.vandenBroek]

Hi all,
Trying to make a little "program" for myself, i am working my way through: 
"Teach yourself python..". Found out that mathematical subject are the topics 
to begin with in simple programming. I am a psychiatrist so i am used to 
associative thinking and pattern recognition instead of logical thinking so 
bare with me please. As a psychiatrist i am doing some research. I wanted to 
program some simple statistics, like finding the median of a list or a mean, 
range and quartiles.
Lists are probably useful in this, so started making a list in a file: 
list.txt: l= [n, n1, n2,.....]
Next tried to make a program with a sorted list as output
#!/usr/local/bin/python 
x = open("list.txt", "rb")
x.read ()
x.sort ()
print x

Tried different options cannot figure out the problem.
Can somebody please enlighten me or point me in a direction,
thanks walter
