accessing the components of a vector

Is there a command in Sage that allows me to access the individual components of a vector? For example, suppose I've defined a vector like a=vector([1,2,3]). I want a command like "a.1" that returns the first component of the vector, so in this case I would want a.1 to return 1. Is there a command like this in Sage? Thanks!

You can use Python sequence indexing syntax, for which the index numbers start at zero: a=vector([1,2,3]);a[0] returns 1.
