First, exception handlingIn the process of running the program, you will always encounter a variety of errors. Program An error stopped running, then we can not let the program stop running it, this time we need to catch the exception, by catching the exception, we do the corresponding processing.Let's begin by writing a function that implements the division operation. 123456789101112 def Calc(a,b): return a/b Print(

Therefore, the formal parameter is only valid inside the function.Actual parameters:Arguments can be constants, variables, expressions, functions, and so on, regardless of the type of argument, and when a function call is made, they must have a definite value in order to pass these values to the parameter.

Last night, I spent a lot of time studying inside the binary tree application to solve the problem of calculation expressions, has been not understood, mainly feel is not their own fault, and lazy, do not want to knock the code to the computer to see, the result of a lot of wasted time. So still remind everyone, code this kind of thing, what a lot of look, think he was wrong to knock himself to the computer to see! In fact, too much, is missing something, resulting in the original code in the pa

" pointer explicitly. But sometimes this is also very useful. 1 If your constructor or class member function has a parameter and a member variable with the same name, you can use this to avoid ambiguity Class something { private: int ndata; Public: Something (int ndata) { this->ndata = ndata; } ; 2 Sometimes the function returns "*this" can be very useful. "*this" is reference to the object. This feature allows us to string functions together so that the output of o

the program conforms to the Richter scale substitution principle, otherwise it violates the Richter scale substitution principle. Let's take a look at a case where the Richter replacement principle is violated under what circumstances. A simple inheritance structure, in subclasses, overrides the method of the parent class of the Calc method. Parent Class Calc: [Java] view plain copy package cn.desig

result. This is a bit like binary tree traversal, but our data structure (Program) is more complex than binary tree traversal. Pattern Matching and Recursion: A simple calculator Since the calculator is the simplest interpreter, why don't we start with the calculator? The following is a calculator that can calculate four arithmetic expressions. These expressions can be nested at will, for example, '(* (+ 1 2) (+ 3 4 )). I want to explain the pattern matching and Recursion principles in this sim

, why the output is not the same? at the time of definition, the value of the default parameter L is computed, that is, pointing to [],l is also a variable, and if the content of L is changed (pointing) at each invocation, the default parameter naturally changes. So: the default parameter must point to the immutable object! The above code can be modified with none:def Testa (l=None): if is none: L=[] l.append ( ' END ' ) return L(c) Variable parametersVariable parameter refers to

object is not changed, the simultaneous reading of objects in a multitasking environment does not require locking, while reading a little bit of a problem. When we are writing a program, if we can design a constant object, we try to design it as an immutable object.variable Parameters :The number of arguments is not sure, you can put a,b,c ...
