I'm having trouble with the concept of a name in Python.

Is a name the same as anything defined? Such as

a, where a = 5
b, where b = [3,4,5]
c, where c = "Alan"
five(), where  def five(): return 5
sqr, where sqr = lambda x: x*x
square, where def sqr(x): return x*x

Are there other kinds of possibilities?
names of classes?
names of modules?
