Introduction to pycharm
PyCharm is a Python IDE that comes with a full set of tools that can help users improve their efficiency when developing with the Python language, such as debugging, syntax highlighting, Project management, code jumping, smart hints, autocompletion, unit testing, and version control. In addition, the IDE provides some advanced features for supporting professional web development under the Django framework.

(2) In the software installation path setting interface, set a reasonable installation path. It is strongly recommended not to install the software to the path of the operating system, otherwise there will be a crash of the operating system and other special circumstances, you must redo the operating system, PyCharm program path under the program will be destroyed.PyCharm default installation path for the operating system path, it is recommended that we change the installation path, and installation of the path is recommended not to use Chinese characters. I chose the installation path for "D:\PyCharm", as shown in Figure 6. Click the "Next" button to create a shortcut to the interface.

(3) Set a shortcut to the PyCharm program in the Create Desktop Shortcut screen. If the computer operating system is 32-bit, select "32-bit launcher", otherwise select "64-bit launcher". Here the computer operating system is a 64-bit system, so choose "64-bit launcher"; Next, set the associated files (Create Associations), check the checkbox to the left of the .py, so that in the future and then open the .py (.py file is a python script) Py (.py file is a python script file, the next we write a lot of programs are .py) file, it will be the default call PyCharm open, as shown in Figure 7.

4 Creating a Project Catalog
In order to store your PyCharm project files conveniently, you have to set the location of the project directory in the Pycharm welcome screen. The method is as follows:
(1) Enter the PyCharm welcome page, click "Create New Project" to create a new project file, as shown in Figure 15.
Figure 15 Pycharm Welcome Screen
(2) PyCharm will automatically set a storage path for the new project file. In order to better manage the project, it is best to set an easy-to-manage storage path, you can directly enter the storage path where the project file will be placed in the Storage Path input box, or you can click the Storage Path Selection button on the right side to open the Path Selection dialog box for selection (the storage path can not be the python storage path that has already been set), as shown in Figure 16.

(3) If you set the installation path through the Path Selection dialog box, you can select an existing folder as the storage path, as shown in Figure 17. You can also click the "new fold" button to create a new folder to store the project files, as shown in Figure 18. Do not set the storage path to the disk where the operating system is located, and try to store the storage path to a path that is easy to find. After the storage path is set, click the Create button to create the project file.

(4) When the creation of the project is completed, you will enter the project list as shown in Figure 19.

(5) When the program is first started, it displays a daily post that provides one tip at a time on the application of Pycharm features. If you want to turn off the Tip of the Day feature, you can check off the Show Tip of the Day checkbox and click the Close button to close the Tip of the Day, as shown in Figure 20. If you want to display the Tip of the Day again at a later time after closing it, you can start the Tip of the Day by clicking the Help→tip of the day menu item in the PyCharm development environment menu.

The previous steps have started the PyCharm development environment, which is next used to write the hello world program in the following steps:
(1) right-click on the just-built dream project, in the pop-up menu, select New--> PythonFile menu item (be sure to select the PythonFile item, this is critical, otherwise you can not follow up on the study), as shown in Figure 21.

(3) in the newly created code editing area to complete the file enter the code "print ("hello world!")". After the completion of the input code will find a small yellow light bulb, as shown in Figure 24, this is the editor of the input code to provide advice, do not pay attention. Select the Run-->Run... menu item to run the program, as shown in Figure 25.

(4) Select "hello world" in the pop-up menu to run the program, as shown in Figure 27.

(5) If there are no errors in the program code, the result of the run will be displayed. As shown in Figure 28.
Figure 28 Program operation results
Description: When writing a program, sometimes the code contains a small yellow light bulb popping up underneath, what is it used for?
There are actually no errors in the program, just some suggestions or reminders from Pycharm to improve the code. Such as adding comments, creating use sources, etc. Displaying a yellow light bulb will not affect the result of running the code, the
