How to set up the Python environment with PyCharm? Detailed tutorial

PyCharm is a powerful Python integrated development environment (IDE) that can help developers improve work efficiency and programming quality. When using PyCharm for Python development, setting up the Python environment is a very important step. This article will introduce in detail how to set up the Python environment in PyCharm, including creating projects, configuring the interpreter and other operations, and provide specific code examples to help readers better understand and operate.

Step 1: Install PyCharm

First, we need to make sure that PyCharm is installed. You can download the installation file from the JetBrains official website and select the appropriate version according to the operating system to download and install. After the installation is complete, open PyCharm and start configuring the Python environment.

Step 2: Create a project

In PyCharm, a project corresponds to a working directory, and all code files will be saved in this project. Next we will create a new project:

1. Open PyCharm, select "File" -> "New Project" in the startup interface or menu bar;
2. In the pop-up window Select "Pure Python" and click "Create";
3. Enter the project name and project saving path, and click "Create" to complete the creation of the project.

Step 3: Configure the Python interpreter

PyCharm needs to know which Python interpreter to use to run the code, so we need to configure the Python interpreter:

1. In the project, click "File" -> "Settings" in the menu bar;
2. Select "Project" -> "Project Interpreter" in the pop-up window;
3. Click on the upper right Click the "Gear" icon in the corner and select "Add..." to add a new interpreter;
4. Select the appropriate Python interpreter, which can be the interpreter that comes with the system or is installed through Anaconda, etc. ;
5. Click "OK" to complete the configuration of the interpreter.

Step 4: Run Python code

After configuring the Python interpreter, we can start writing and running Python code in PyCharm. Next, a simple example will be used to demonstrate:

1. Create a new Python file in the project, such as "hello.py";
2. Enter the following code:

print("Hello, PyCharm!")

3. Click the green triangle button on the left side of the code editing window or use the shortcut key "Shift F10" to run the code;
4. "Hello, PyCharm!" will be output in the console, indicating The code runs successfully.

Summary

Through the above steps, we have learned how to set up the Python environment in PyCharm, including creating projects, configuring the interpreter, and running code. PyCharm provides many functions and tools to help Python developers improve programming efficiency. I hope this article will be helpful to you.
