6. The founder of the Python language explains why the indexing of Python arrays starts from 0
Introduction: Someone recently asked me on Twitter why Python uses 0-based array indexing (hereinafter referred to as 0-based), and asked me to read an article on this topic (very interesting) . This brought back a lot of memories for me. ABC language, one of the ancestors of Python, uses a 1-based indexing method (hereinafter referred to as 1-based), while C language, another language that has a huge influence on Python, uses 0-based Way. Some of the first languages I learned (Algol, Fortran, Pascal) were 1-based and some were fluid. I think the reason why I decided to let Python use 0-bas
7. Is python worth learning? Outlook for the future development of the Python language in 2017
Introduction: Is Python worth learning? What is the future development of the Python language? I have been developing PHP for ten years, and have also done projects of all sizes. In the past one or two years, I have been attracted by a programming language, that is, Python. In various forums and attention circles, Python has attracted a lot of attention. The quality has always been very high, and I have also taught myself python,
8. Summary of several mistakes that Python novices often make
#Introduction: There are some small pitfalls in the Python language, which are particularly easy to confuse and make mistakes. Beginners can easily fall into them if they are not careful. Below I will give you an in-depth analysis of some of these pitfalls. I hope it will be helpful to beginners. Friends who need it can refer to it. Let’s take a look together.
9. Share your Cython installation and usage experience
##Introduction: It is a tool used to quickly generate Python extension modules (extension modules). Its syntax is a mixture of python language syntax and c language syntax. It is easier to write python extension modules than swig. Maybe you will say swig. You can directly participate in basic exercises through the c header file
10. Transfer of functions in python language
Introduction: First explain how to use Chinese when writing a Python script. You can add the following code segment at the beginning of the script: # _*_ coding:utf-8 _ *_ The effect is the same as #coding=utf-8. Here is a summary of how to pass parameters when learning Python to define functions: 1. First, positional parameters and default values: Define a function func_name, where the formal parameter is arg ,a

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
