Components of Points

[raman kurdi]

Hi,
I need a command which separate the components of points. For example
let P=(2,4).
I need the first component of this point.
Could you please help me?

sage: P=(2,4)
sage: P[0]
2
sage: P[1]
4

Just to make it clear, you are really taking items from a "Python tuple".  If you are talking about actual "points" in the graphical sense, you'd need to do something else.

sage: P = point((2,3))

sage: p = P[0]

sage: p.xdata

[2.0]
