What is Third Party Library | Summary and Q&A

TL;DR

Python standard libraries come pre-installed with Python, but for additional functionality, we need to install third-party packages using pip.

Key Insights

• 😒 Python standard libraries are readily available for use in programs without separate installation.
• 🥳 Third-party packages can extend Python's functionality by providing additional features and tools.
• 🥳 Pip is the recommended method for installing and managing third-party packages in Python.
• 🍵 Pip handles dependencies, ensuring that all required packages are downloaded and installed.
• 👨‍🔬 Using pip, we can easily search for packages and install them with a single command.
• 🎰 Pip is specific to Python 3, so the command may vary depending on the Python version and machine.

Questions & Answers

Q: What are Python standard libraries?

Python standard libraries are pre-installed modules in Python that provide a wide range of functionality for tasks like file handling, network operations, and data manipulation.

Q: How do we install third-party packages in Python?

We can use pip, the Python package manager, to install third-party packages. The command for installation is 'pip install <package_name>' or 'pip3 install <package_name>'.

Q: What does pip do when installing a package?

Pip checks if the package is already installed on the machine. If not, it searches its repositories, downloads the package, and installs it. Pip also handles any dependencies required by the package.

Q: How can we check if pip is installed on our machine?

We can run the command 'pip -v' or 'pip3 -v'. If it gives an error, pip is not installed. In that case, we can install it using 'sudo apt-get install python3-pip' on a Linux machine.

Summary & Key Takeaways

• Python has standard libraries that come pre-installed and can be used directly in programs without separate installation.

• If we need additional functionality not provided by standard libraries, we can install third-party packages using pip.

• Pip is a Python package manager that allows us to search for, download, and install packages.
