The "lambda functions" was an unclear part of the tutorial I read.
Should I use them? Are they pythonic?
As far I see they are good

You mean without _explicitely_ calling a function.
May I inquire why you need to write f instead of f(x)?
an automatic way that depends on changing the value of x. as each time
x=something used t

Thanx.
It just popped in my mind.
in 3d programming there are transformation matrices like
a=[[cos(x),sin(x),0],[-sin(x),cos(x),0],[0,0,1]]
it is a 3x3 matrix. never changes during program.
it can be defined like
>>> def transmat(x):
... dummy=[[0,0,0],[0,0,0],[0,0,0]]
... d

You had a list of lambda functions in your first post and in the
subject line still. How is that not what you wanted?
