[Tutor] how to use

[Alan Gauld]

Hi Anil,

Are you reading a tutorial?
Most of the questions you are asking should be covered
in any standard tutorial.

> what does

> x**x) do?

Its equivalent to

pow(x,x)
ie raises x to the power x.

> 2nd) what is the key for the dictionary, i assume x is the value of 
> the dictionary

> dict((x, x**x) for x in range(10))

x is the key and x**x is the value.
