Programming languages are used for a variety of tasks, from creating simple scripts to building complex software applications. Here are some examples of what different programming languages are commonly used for:

1. Python: Python is a general-purpose language that is used for a variety of tasks, including data analysis, machine learning, web development, and automation.
2. Java: Java is another general-purpose language that is used for building enterprise-level software applications, mobile apps, and Android applications.
3. JavaScript: JavaScript is a language primarily used for building dynamic web pages and web applications. It is also used for creating mobile apps and building server-side applications.
4. C and C++: C and C++ are low-level programming languages used for building operating systems, device drivers, and embedded systems.
5. Swift: Swift is a language developed by Apple for building iOS and macOS applications.
6. PHP: PHP is a language primarily used for building dynamic websites and web applications.
7. Ruby: Ruby is a language used for building web applications, especially those built using the Ruby on Rails web framework.
8. SQL: SQL is a language used for managing and querying relational databases.

These are just a few examples of the many programming languages available, and their uses can overlap or be extended beyond their intended purposes. Ultimately, the choice of programming language depends on the specific task or application being developed, as well as the preferences and skills of the programmer.
