How to add a library in PyCharm? Detailed tutorial sharing

In Python development, third-party libraries are often used to help us complete tasks more efficiently. As an excellent integrated development environment, PyCharm provides us with a convenient way to manage and add libraries. This article will introduce in detail how to add libraries in PyCharm, and attach specific code examples to help readers better master this technique.

1. Using PyCharm’s Package Manager

PyCharm comes with a convenient package manager that can help us easily add the required libraries. The following are the specific steps:

Open PyCharm and enter your project.
Click "File" on the top menu bar and select "Settings".
In the pop-up settings window, select "Project:" and then click "Python Interpreter".
In the Python Interpreter page, click the " " button in the upper right corner.
Enter the name of the library you want to add in the search box, such as "numpy", and then click "Install Package".
After the installation is completed, you can use the library in your project.

2. Use the pip tool

If PyCharm's Package Manager cannot meet the needs, we can also use the pip tool to manually add the library. The following are the specific steps:

Open PyCharm and enter your project.
Open the terminal and click the "Terminal" tab at the bottom in PyCharm.
Enter the following command in the terminal to install the required libraries, taking "numpy" as an example:
```
pip install numpy
```
After the installation is completed, you can use it in the project library.

3. Use the requirements.txt file

Sometimes we need to record all the libraries required for the project so that they can be reinstalled on other computers. . You can use the requirements.txt file at this time. The following are the specific steps:

Create a new text file and name it requirements.txt.
List all libraries required for the project and their version numbers in the file, for example:
```
numpy==1.18.1
matplotlib==3.1.3
```
Save and close the file.
Open the terminal and run the following command in the project directory:
```
pip install -r requirements.txt
```
After all libraries are installed, you can start developing the project.

Through the above method, we can add the required libraries in PyCharm conveniently and quickly. During the development process, good library management can improve our development efficiency and make our projects more robust and efficient. I hope the above content can be helpful to readers.
