　　Before you implement the progress bar, learn the makefile first.There are countless source files in a project, which are placed in several directories by type, function and module, and makefile defines a series of rules to specify which files need to be compiled first, which files need to be compiled, which files need to be recompiled, and even more complex functional operations. Make is a command tool that is a command tool that interprets instructions in makefile.Beginners can only implement

A class of Python applications is best to use an interactive user interface, which eliminates the overhead or complexity of the graphics environment. Interactive text-mode programs (in Linux/unix), such as ncurses libraries encapsulated in the standard curses modules of Python, are exactly what you need. In this article, Davidmertz discusses the use of curses in Python. He describes the curses environment using the sample source code from the front end to the txt2html program. The Curses Librar

Before learning to compile, always do not know the teacher in the line, always hit a newline character and carriage return , originally they have such a story .... A long time ago, there was a machine called a Telex typewriter (teletype Model ASR) , and there was no such thing as a computer. On this typewriter, there is a part called carriage , it is the type head, the equivalent of the typewriter cursor. Each character is entered, and the cursor adv

The difference between Linux and Windows return line break source of the problem: "Carriage return" (carriage return) VS "line feed"Before the computer appeared, there was a gadget called a telex typewriter (teletype Model 33) that could play 10 characters per second. But it has a problem, that is, when the line is finished, it will take 0.2 seconds to hit two characters. If there are new characters coming in this 0.2 seconds, then this character wil
