Python - Lambda expression is an anonymous function. Lambda expression is named based on the lambda calculus in mathematics. It directly corresponds to the lambda abstraction. It is an anonymous function, that is, a function without a function name.

Python was designed in the early 1990s by Guido van Rossum of the Dutch Society for Mathematics and Computer Science as a replacement for a language called ABC. Python provides efficient high-level data structures and enables simple and effective object-oriented programming.

Python syntax and dynamic typing, as well as the nature of an interpreted language, make it a programming language for writing scripts and quickly developing applications on most platforms. With the continuous updating of versions and the addition of new language features, it has gradually become more popular. Used for the development of independent, large-scale projects.

The Python interpreter is easily extensible and can be extended with new functions and data types using C or C++ (or other languages ??that can be called from C). Python can also be used as an extension programming language in customizable software. Python's rich standard library provides source code or machine code suitable for each major system platform.

The development history of Python:

Since the birth of the Python language in the early 1990s, it has been gradually widely used in system management tasks processing and web programming.

The founder of Python is the Dutchman Guido van Rossum. During the Christmas period of 1989, in Amsterdam, Guido decided to develop a new script interpreter as an inheritance of the ABC language in order to kill the boredom of Christmas. The reason why Python was chosen (as the name of the programming language) is taken from the British TV comedy "Monty Python's Flying Circus" that premiered in the 1970s.

ABC was designed by Guido A teaching language. In Guido's opinion, the ABC language is very beautiful and powerful, and is specially designed for non-professional programmers. However, the reason why the ABC language has not been successful is that it is not open. Guido was determined to avoid this mistake in Python. At the same time, he also wanted to achieve things that had been flashed in ABC but had not been implemented. In this way, Python was born in Guido's hands. ABC was developed mainly under the influence of Modula-3 (another very elegant and powerful language designed for small groups) and combined the conventions of the Unix shell and C.
