It is a popular programming language for Machine Learning and Deep Learning applications. Python is used for scientific and computational applications like FreeCAD and Abacus, and it is also by popular websites like YouTube, Quora, Pinterest, and Instagram.

2. JAVA

Java is widely used in web and application development as well as Big Data. Java is also used in the backend of several popular websites, including Google, Amazon, Twitter, and YouTube.
