Dear, this is the LearingYard Academy!

Today, the editor brings the

“The Difference and Environment Construction between Python and C Language”.

Welcome to visit!

一、思维导图

此推文关于零基础入门学习Python系列的内容主要如下:

The main content of this tweet about the exercise series is as follows:

本次推文通过语法知识和案例的结合来为大家讲解Python,但需要注意的是代码还是需要经常敲才能熟练。

This tweet combines grammar knowledge and case studies to explain Python to everyone, but it should be noted that the code still requires frequent typing to become proficient.

二、C语言与Python的区别

(一)语言类型不同

Python是动态类型的语言,确定变量的类型是在第一次被赋值的时候;C语言是静态类型的语言,需要声明数据类型。

(二)内存管理不同

Python使用自动垃圾收集器进行内存管理,但是在C语言中必须自己管理。

(三)对象机制不同

Python中的每一个东西都是对象,每一个对象都有三种属性——实体、类型和值。但是C语言没有对象这个概念,因此比较字符串必须使用strcmp来比较。

(四)运行速度不同

Python运行速度比C语言慢

(五)函数库的调用方法

Python中用import引入

C语言中需要用include引入头文件

(1) Different language types

Python is a dynamically typed language that determines the type of a variable when it is first assigned a value; C language is a statically typed language that requires declaring data types.

(2) Different memory management

Python uses an automatic garbage collector for memory management, but in C language, it must be managed by itself.

(3) Different object mechanisms

Everything in Python is an object, and each object has three attributes - entity, type, and value. However, C language does not have the concept of objects, so comparing strings must use strcmp.

(4) Different operating speeds

Python runs slower than C language

(5) Calling methods for function libraries

Introducing with import in Python

In C language, you need to use include to import Header file

三、环境搭建

编译器:IDLE

虽然Pycharm有更好的开发环境,但是它其中的提示信息不利于初学者学习。

补充:在IDLE中输入import this会打印出一首诗

Compiler: IDLE

Although Pychar has a better development environment, its prompt information is not conducive to beginner learning.

Supplement: Entering import this in IDLE will print out a poem
