Python与C：知道有什么区别

Introduction

Python is an interpreted, high-level, general-purpose programming language.

C is a general-purpose, procedural computer programming language.

Python是一种解释性的高级通用编程语言。

C是一种通用的过程计算机编程语言。

Speed

Interpreted programs execute slower as compared to compiled programs.

Compiled programs execute faster as compared to interpreted programs.

与已编译程序相比，已解释程序的执行速度较慢。

与解释程序相比，编译程序的执行速度更快。

Usage

It is easier to write a code in Python as the number of lines is less comparatively.

Program syntax is harder than Python.

用Python编写代码更容易，因为行数相对较少。

程序语法比Python难。

Declaration of variables

There is no need to declare the type of variable. Variables are untyped in Python. A given variable can be stuck on values of different types at different times during the program execution

In C, the type of a variable must be declared when it is created, and only values of that type must be assigned to it.

无需声明变量的类型。变量在Python中是无类型的。给定变量可以在程序执行期间的不同时间停留在不同类型的值上

在C语言中，变量的类型必须在创建时声明，并且只有该类型的值必须分配给它。

Error Debugging

Error debugging is simple. This means it takes only one in instruction at a time and compiles and executes simultaneously. Errors are shown instantly and the execution is stopped, at that instruction.

In C, error debugging is difficult as it is a compiler dependent language. This means that it takes the entire source code, compiles it and then shows all the errors.

错误调试很简单。这意味着一次只需要一条指令，并且可以同时编译和执行。该指令立即显示错误并停止执行。

在C语言中，错误调试是困难的，因为它是编译器相关的语言。这意味着它将获取整个源代码，对其进行编译，然后显示所有错误。

Function renaming mechanism

Supports function renaming mechanism i.e, the same function can be used by two different names.

C does not support function renaming mechanism. This means the same function cannot be used by two different names.

支持功能重命名机制，即同一功能可以被两个不同的名称使用。

C不支持功能重命名机制。这意味着同一功能不能被两个不同的名称使用。

Complexity

Syntax of Python programs is easy to learn, write and read.

The syntax of a C program is harder than Python.

Python程序的语法易于学习，编写和阅读。

C程序的语法比Python难。

Memory-management

Python uses an automatic garbage collector for memory management.

In C, the Programmer has to do memory management on their own.

Python使用自动垃圾回收器进行内存管理。

在C语言中，程序员必须自己进行内存管理。

Applications

Python is a General-Purpose programming language.

C is generally used for hardware related applications.

Python是一种通用的编程语言。

C通常用于与硬件相关的应用程序。

Built-in functions

Python has a large library of built-in functions.

C has a limited number of built-in functions.

Python具有大量的内置函数库。

C具有有限数量的内置函数。

Implementing Data Structures

Gives ease of implementing data structures with built-in insert, append functions.

Implementing data structures requires its functions to be explicitly implemented

使用内置的insert，append函数可以轻松实现数据结构。

实施数据结构需要明确实现其功能

Pointers

No pointers functionality available in Python.

Pointers are available in C.

Python没有可用的指针功能。

指针在C中可用。
