What is the method for adding libraries in PyCharm?

There are several ways to add libraries in PyCharm.

1. Utilize PyCharm’s built-in package manager: Open PyCharm, go to File -> Settings -> Project -> Project Interpreter. In the window that appears, click on the plus sign button in the top right corner, search for and select the library you want to install, and then click install.
2. To install a library, use the pip command line tool. Open a terminal or command prompt and enter the following command.
3. Install the package with the name specified.
4. To utilize the requirements.txt file, create a file with the name requirements.txt in the project’s root directory. List the libraries and their versions to be installed in the file. Then, navigate to the project’s root directory in the terminal or command prompt and run the following command to install the listed libraries.
5. Install the dependencies listed in the requirements.txt file by using the following command: “pip install -r requirements.txt”

Upon completion of the installation, PyCharm will automatically recognize the installed libraries and provide relevant code completion and suggestions in the code.
