Python与C：知道有什么区别
编程是一种建立职业道路的有趣且有利可图的方法，但是您需要在真正开始学习这项技能之前先清除某些事情。摆在您面前的主要选择之一是编程语言的选择（示例– Python vs C）。在开始学习任何形式的编程之前，您需要确定哪种语言最适合您。
Python与C的比较可能会导致很多观点，因为每个程序员都会有自己的观点。在此博客中，我试图汇编其中的一些内容，以便为您提供清晰的画面。

| 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. |
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。 |
Python程式范例–
print("Hello, World!")C程序示例–
#include <stdio.h>
int main()
{
// printf() displays the string inside quotation
printf("Hello, World!");
return 0;
}Python和C语言相似，但有很多区别。在决定使用特定语言之前，请考虑以下几点–
易于开发- Python的具有较少的关键字和更多免费的英语语言的语法，而Ç是写比较困难。因此，如果您想简化开发过程，请使用Python。
性能 – Python比C慢，因为它需要大量的CPU时间来解释。因此，速度C是更好的选择。
