How to Check PyYAML Version

Python Programming Language has various libraries and packages for making tasks easier and more efficient. One such library is PyYAML, which is widely used for parsing and writing YAML, a human-readable data serialization standard. In this article, we will see different methods to check the PyYAML version installed on our system.

What is PyYAML?

PyYAML is a Python library that allows for the parsing and writing of YAML, which stands for "YAML Ain't Markup Language." YAML is a human-readable data serialization format often used for configuration files and data exchange between languages with different data structures. PyYAML provides tools to convert Python objects to and from YAML, making it easier to work with configuration files and structured data in a readable and editable format. The library supports a wide range of features, including custom tags and anchors, and integrates well with other Python libraries.

Checking the Installed Version of PyYAML

Before we can check the version of PyYAML, we need to first install PyYAML on our system. You can refer to the following links to install it on your system, depending on the type of Operating System that you are using:

• Windows
• MacOS

We can check the installed version of PyYAML in many different ways. Let us see them one by one.

Using Python PIP

Python pip is a package manager that allows the users to install, update and manage packages. We can use pip to check the version of PyYAML installed on the system by writing the following command in the command prompt or terminal. his command will display detailed information about the PyYAML package, including its version.

pip show pyyaml

Output:

Writing Python Script

Another way is to write a Python script with the following code. The __version__ method of the yaml module gives the current installed version of PyYAML installed on the system.

import yaml
print(yaml.__version__)

Output:

Using Conda

We can also check PyYAML version in case you are using Anaconda or Miniconda. You simply need to open the anaconda prompt and write the following conda command in the terminal window.

conda list pyyaml

Output:

Updating PyYAML

In programming, it is crucial to keep the packages and their dependence up to date for a smooth functioning. For updating the version of PyYAML, we can use the following pip command. Execute this command in any of the terminal supported by the system.

pip install --upgrade pyyaml

Conclusion

In conclusion, managing the version of PyYAML is a simple process that ensures your Python environment uses the latest features and fixes. By using the Python interactive shell or the VSCode terminal, you can easily check the installed version of PyYAML. Additionally, updating PyYAML to the latest version is a simple task using the pip command. Staying up-to-date with library versions helps maintain compatibility and improves the efficiency of your Python projects.
