No. parameters are what you use when you create the function definition. For example def f(x): return 2*x x is the parameter. Now when I call f() I must pass in a value (or variable with a value). The thing I pass in when I call f() is the argument. f(2) 2 becomes the argument for this particular call to f. The parameter x of f takes on the value 2 during this particular invocation. z = 7 f(z) z is now the argument of f for this invocation. The parameter x takes on the value 7, which is the value of the argument, z x is always the parameter of f() but the argument can change each time you call f() HTH, Alan G.
