关键区别 - Perlvs python
A computer program provides instructions for a computer to perform tasks. A set of instructions is known as a computer program. A computer program is developed using a programming language.高级语言are understandable by programmers but not understandable by the computer. Therefore, those programs are converted to machine-understandable format. Perl and Python are two high-level programming languages. Perl has features such as built-in regular expressions, file scanning and report generation. Python provides support for common programming methodologies such as data structures,算法etc. The关键区别在Perl和Python之间Perl强调对常见的以应用程序为导向的任务的支持,而Python则强调对常见编程方法的支持。

什么是珀尔?
Perl是通用高级编程语言。它是由拉里·沃尔(Larry Wall)设计的。Perl代表实际提取和报告语言。这是open sourceand is useful for text manipulation. Perl runs on various platforms such as Windows, Mac, Linux etc. It is a multi-paradigm language that supports mainly procedural programming andobject-oriented programming。程序编程有助于将程序分为功能。面向对象的编程有助于使用对象建模软件或程序。
佩尔是一种解释的语言。因此,每行都是由口译员。High-level language programs are understandable by the programmer, but they are not understandable by the machine. Therefore, the instructions should be converted into the machine-understandable format. Programming languages such asC and C++converts thesource code使用编译器到机器语言。在Perl中,该程序首先转换为字节码,并将字节码转换为机器指令。因此,与C ++等语言相比,Perl是较慢的语言。
有不同的方法可以运行PERL程序。可以从命令行以交互式模式启动编码。程序员还可以创建Perl脚本并运行它们或使用综合开发环境(IDE)构建应用程序。Perl的一些常见IDS是Padre,Perl IDE和Eclipse插件Epic - Perl编辑器。Perl支持不同的数据类型。标量变量以$开头。它可以存储字符串,整数或参考。数组变量以 @开头。它用于存储订购的标量列表。哈希变量从%开始。它用于存储钥匙,值对。
与Web相关技术(例如Hyper Text Markup语言)易于使用PERL(HTML),XMLetc. Perl can be used to develop Graphical User Interfaces (GUI) too. It is also easy to integrate Perl with databases such asmysql,Postgres等。Perl是一种可用于开发各种应用程序的语言,例如Web开发,网络编程和系统管理。
什么是python?
Python is a general-purpose high-level programming language. It was designed by Guido van Rossum. It is a cross-platform and open source language. Python programs are easier to read, write and learn. Those programs are also easy to test and debug. Python is a preferred programming language for beginners because of its simplicity. Python is a multi-paradigm programming language. It mainly supports procedural and object-oriented programing languages.
Python is an interpreted language. Therefore, each line is read one statement after the other. Python programs are understandable by the programmer and not understandable by the machine. Therefore, the instructions should be converted into machine understandable format using the Python interpreter. First, the instructions are converted into bytecode then the bytecode converts to machine code. So, Python is slower than compiled languages such as C and C++.
程序员可以使用Python Interactive模式,Python脚本或使用集成开发环境(IDE)运行Python程序。Pycharm和Eclipse是Python开发的一些常见。Python支持数据类型,例如数字,字符串,列表,元组和词典。Python语言用于开发各种应用程序,例如Web开发,自然语言处理和机器语言。
What are the Similarities Between Perl and Python?
- 两者都支持程序和面向对象的编程。它们是多范式语言。
- Both are interpreted languages.
- 两者都是高级编程语言。
- Both are open source and cross-platform.
- 与基于编译器的语言(例如C,C ++)相比,两种语言的速度都较慢。
- Both are case sensitive programming languages.
- 两者都可以用于开发图形用户界面。
- Both can be integrated with databases such as MySQL, Postgres, Oracle etc.
What is the Difference Between Perl and Python?
Perl vs Python |
|
Perl是一种高级,通用,解释,动态编程语言。 | Python is an interpreted high-level programming language for general purpose programming. |
主要焦点 | |
Perl强调对以应用程序为导向的任务(例如报告生成和文件扫描)的支持。 | Python emphasizes support for common programming methodologies such as data structure design and object-oriented programming. |
文件扩展名 | |
珀尔Scripts are saved with the .pl file extension. | Python脚本用.py文件扩展名保存。 |
Data Types | |
Perl包含数据类型,例如数字,字符串,标量,数组,哈希。 | Python contains data types such as numeric, strings, lists, dictionaries, tuples. |
Semi-colon | |
In Perl, all statements should end with a semi colon. | 在Python,不必用半结肠结束陈述。 |
语句块 | |
Perl使用括号来标记语句块。 | Python使用凹痕来标记语句块。 |
Designer | |
佩尔是由拉里·沃尔(Larry Wall)设计的。 | Python由Guido Van Rossum设计。 |
Testing and Debugging | |
Perl掠夺rams are harder to test and debug than Python programs. | Python程序比Perl程序更容易测试和调试。 |
摘要 - Perlvs python
本文讨论了Perl和Python之间的差异。Python鼓励程序员编写比Perl更可读的程序。Perl和Python之间的主要区别在于,Perl强调对常见的面向应用程序的任务的支持,而Python则强调对常见编程方法的支持。Python比Perl更受欢迎。
