It has also been used in several video games, and has been adopted as first of the three available programming languages in Google App Engine, the other two being Java and Go. Python is also used in algorithmic trading and quantitative finance. Python can also be implemented in APIs of online brokerages that run on other languages by using wrappers. Python is commonly used in artificial intelligence projects with the help of libraries like TensorFlow, Keras and Scikit-learn. As a scripting language with modular architecture, simple syntax and rich text processing tools, Python is
Python syntax and semantics among Python users has been removing tabs as block markers; other Python users propound removing spaces instead). Moreover, formatting routines which remove whitespace—for instance, many Internet forums—can destroy the syntax of a Python program, whereas a program in a bracketed language would merely become more difficult to read.

All variables in Python hold references to objects, and these references
