WebBy default, a function must be called with the correct number of arguments. Meaning that if your function expects 2 arguments, you have to call the function with 2 arguments, not more, and not less. Example Get your own Python Server. This function expects 2 arguments, and gets 2 arguments: def my_function (fname, lname):

Here are all of the methods of list objects:
WebBrent's method is a combination of the bisection method, the secant method and inverse quadratic interpolation. At every iteration, Brent's method decides which method out of these three is likely to do best, and proceeds by doing a step according to that method. This gives a robust and fast method, which therefore enjoys considerable popularity. http://scipy-lectures.org/advanced/mathematical_optimization/auto_examples/plot_1d_optim.html
