What is the difference between golang and python

With the rapid development of information technology, programming languages ​​have received more and more attention. As two high-profile programming languages, the differences between golang and python are increasingly obvious. This article will analyze the differences between golang and python from many aspects such as language development history, language characteristics, and application scenarios.

1. Development History

Go language (golang for short) is an open source project launched in 2007 by Robert Griesemer, Rob Pike and Ken Thompson of Google. A statically typed programming language that combines the safety and performance of traditional compiled languages ​​with the efficiency of C/C and the development speed of Java. The first stable version of the Go language was released in 2009.

Python is an old programming language invented by Guido van Rossum in 1989. Its initial version was released in 1991. As an interpreted high-level language, Python's development goals are easy to learn, beautiful code, rich libraries and high efficiency. Now Python has become one of the most popular programming languages.

Overall, golang is a relatively new programming language, while Python has a longer development history.

2. Language features

(1) Type system:

Golang is a statically typed programming language, and variables must specify their type when they are defined. , this strong type checking mechanism is conducive to error detection during the coding phase and also improves the security of program operation.

Python is a dynamically typed programming language, that is, the type of variables is determined at runtime. This feature allows developers to write code faster and use data types more flexibly.

(2) Memory management:

Golang has an automatic garbage collection mechanism that can promptly recycle the memory occupied by useless variables. This automatic processing and automatic memory recycling mechanism greatly reduces the developer's workload. burden.

Python's garbage collection mechanism is also automated, but Python's garbage collection mechanism relies on reference counting, which also leads to certain performance problems when Python handles large-scale memory operations.

(3) Concurrency mechanism:

Golang has an excellent concurrency mechanism, allowing multiple threads to run at the same time, improving the throughput and performance of the program.

Python’s concurrency mechanism is relatively weak, and the original Python does not have a native multi-threading mechanism. Although Python provides GIL (Global Interpreter Lock) to control problems when multiple threads access the interpreter at the same time, this will also affect the performance of the program.

(4) Package management:

Golang has a built-in package manager to facilitate package management and dependency management for developers.

Python also has built-in package managers and dependency management tools, such as pip and conda, but developers need to manually manage dependencies and version compatibility.

3. Application fields

Golang is more suitable for developing network programs, distributed systems, cloud platforms and other fields because it has excellent features such as high concurrency and maintainable code specifications.

Python is suitable for data science, artificial intelligence, natural language processing, Web back-end and other fields because of its advantages such as fast development speed, good code readability, and rich scientific computing libraries.

4. Summary

Golang and Python are two different programming languages. Which language to choose depends on the specific scenario. Unless there are clear special needs, both are excellent choices. Python is widely used in the fields of data science, web back-end and artificial intelligence, while golang is particularly suitable for developing high-concurrency applications, distributed systems and cloud platforms.
