Combined, there are approximately 8.7 million Perl and Python developers around the world, reflecting their popularity and utility in various domains.

If you’re trying to decide which scripting language to learn or use for your next project, you might be asking yourself: Should I choose Perl or Python? Which language is more suitable for web development or text processing tasks?

In this article, we will delve into the key differences between Perl and Python, comparing their features, advantages, and use cases. By the end, you’ll be better equipped to make an informed decision on which scripting language aligns best with your project requirements and career goals.

What Is Perl?

Perl is a high-level, general-purpose, interpreted, and dynamic programming language used by 1,640,187 websites around the world. It was initially designed for text processing and has since evolved to be used for a wide range of programming tasks. 

Perl features include its powerful regular expression engine, extensive text manipulation capabilities, and the Comprehensive Perl Archive Network (CPAN) which offers a vast repository of software and documentation.

One of the key advantages of Perl is its robust regular expression support, enabling developers to easily manipulate and extract information from text data. This makes Perl particularly well-suited for tasks such as data parsing, text processing, and pattern matching.

Perl’s extensive text manipulation capabilities empower developers to handle complex and large-scale text datasets efficiently. Its rich set of built-in functions and modules allows for quick and efficient text processing operations.

Perl’s Comprehensive Perl Archive Network (CPAN) provides a vast collection of ready-to-use software modules, libraries, and documentation. This community-driven resource allows developers to easily access and leverage pre-existing solutions, saving time and effort in custom software development.

Pros of Perl:

1. Flexible text processing: Perl’s powerful regular expression engine and text manipulation capabilities make it an ideal choice for tasks involving text processing and data extraction.
2. Extensive libraries and modules: The Comprehensive Perl Archive Network (CPAN) offers a vast repository of software modules and libraries, enabling developers to easily access and leverage existing solutions.
3. Widely used in system administration and network programming: Perl’s versatility and adaptability make it a popular choice for system administration tasks and network programming.

Cons of Perl:

1. Complex syntax: Perl’s syntax can be complex and difficult to read, which may discourage new programmers.
2. Declining popularity: While Perl continues to be widely used in certain domains, its popularity has waned over time, making it less appealing to new programmers. Perl is now used by only 0.1% of websites.

What Is Python?

On the other hand, Python is used by 48.9% of developers globally. Python is a high-level, interpreted programming language known for its simplicity and readability. It was designed with an emphasis on code readability and simplicity, making it a popular choice among beginners and experts alike.

Python features include its extensive libraries, cross-platform compatibility, and strong community support. The language’s extensive library ecosystem provides developers with a wide range of pre-built modules and tools, allowing for rapid development and increased productivity.

One of Python’s key advantages is its cross-platform compatibility, meaning that Python code can run on various operating systems without the need for extensive modifications. This flexibility makes it an attractive choice for developers working on multiple platforms.

In addition to its practical benefits, Python’s strong community support is another significant advantage. The Python community, consisting of developers, educators, and enthusiasts, is known for its willingness to help and share knowledge. The vast resources available, including extensive documentation, online forums, and active user groups, ensure that developers can easily find assistance and solutions to their coding challenges.

However, it is essential to acknowledge some of Python’s limitations. Unlike compiled languages such as C++ or Java, Python’s interpreted nature can lead to slower performance in some cases. This is especially true for computationally intensive tasks, where lower-level languages might offer more efficient solutions.

While Python excels in web development, data analysis, and scientific computing, it is not as commonly used in mobile application development compared to languages like Java or Swift. If mobile app development is a primary requirement, it may be worth considering other languages specifically tailored for mobile platforms.

Perl vs Python: Key Differences

When comparing Perl and Python, there are several key differences to consider. These differences include syntax, performance, philosophy, community, popularity, readability, code style, and applications.

Syntax Differences

One major difference between Perl and Python is in their syntax. Perl’s syntax is known for being more complex and flexible, allowing developers to write concise code. On the other hand, Python prioritizes readability with its clean and straightforward syntax, making it easier for beginners to learn and understand code.

Performance Comparison

Performance is another aspect where Perl and Python differ. Since Perl is an interpreted language, it might be slower than Python, which is also an interpreted language but known for its optimized runtime performance. However, both Python and in particular Perl are faster than Rexx and Tcl.

Popularity

When it comes to popularity, Python has gained significant traction in recent years and has become one of the top programming languages. Perl, although still being used in specific domains, has experienced a decline in popularity compared to its peak. 1.4% of sites on the internet use Python as opposed to 0.9% of websites that use JavaScript.
