A must-read to become a master of PyCharm: Learn how to package a project completely

A must-read for newbies to PyCharm: A complete guide to project packaging, specific code examples are required

Introduction:
In the software development process, project packaging is very important step. Packaging brings our code and required resources together for easy deployment and sharing. As a commonly used Python integrated development environment, PyCharm provides powerful packaging functions. This article will introduce in detail the complete process of using PyCharm for project packaging for newbies to PyCharm, with specific code examples.

Directory:

1. Create project
2. Set project dependencies
3. Build project structure
4. Write code
5. Configure packaging options
6. Packaging project
7. Create project:
   First, create a new project in PyCharm. Click the "File" menu, select "New Project", and then set the name and path of the project as needed. Click the "OK" button to complete the creation of the project.
8. Set project dependencies:
   During the project development process, it is often necessary to use third-party libraries or modules. In PyCharm, we can use virtual environments to manage project dependencies. Click the "File" menu, select "Settings", then select "Project: [project name]" in the left panel, and then click the "Python Interpreter" tab. The Python interpreter used by the current project is displayed on the right.

If the project does not use a virtual environment, you can click the "Show All" button, select the required third-party library and click the "Install Package" button to install it. If your project uses a virtual environment, you can switch to the virtual environment and install the required libraries.

3. Build the project structure:
   A good project structure helps organize and manage the code. In PyCharm, you can add folders and files by right-clicking the project folder and selecting "New" in the pop-up menu to build a clear project structure.
4. Write code:
   Add Python files in the project structure and start writing project code. In the PyCharm editor, you can use rich code editing functions, such as code completion, syntax checking, etc., to improve development efficiency.

The following is a simple sample code:

# main.py

def add(a, b):
    return a + b
     
def subtract(a, b):
    return a - b

5. Configure packaging options:
   In PyCharm, we can use the pyinstaller library for project packaging. First, you need to install the pyinstaller library in the project's virtual environment. Open the terminal and enter the following command in the terminal:

pip install pyinstaller

After the installation is complete, return to PyCharm, click the "File" menu, select "Settings", and select "Build, Execution," on the left panel. Deployment" and select the "Python Interpreter" tab. In the right panel, click the plus button in the upper right corner, search for pyinstaller, and click the "Install Package" button to install it.

6. Packaging the project:
   Before packaging the project, we need to configure pyinstaller. Click the "File" menu, select "Settings", select "Build, Execution, Deployment" on the left panel, and then select the "Console" tab. In the right panel, find the "Python Console" line, click the "Show" button to expand it, and select the "Emulate terminal in output console" option.

Go back to the PyCharm project structure, right-click on the main file (such as main.py in the example above), and select "Open in Terminal" in the pop-up menu. In the terminal, enter the following command to package:

pyinstaller main.py

After the command is executed, the dist folder will be generated in the project structure, which contains the packaged executable file.

Summary:
This article details the complete process of project packaging in PyCharm through specific steps and code examples. Through reasonable project structure and dependency management, we can better organize and manage project code. With the powerful features provided by PyCharm, such as code editing and packaging tools, we can develop and deploy our Python projects more efficiently. I hope this article can provide some help and guidance to PyCharm newbies.
