Which Is Not a Commonly Used Programming Language for AI?

Verified Sources
Nov 4, 2026

In typical AI coursework and industry practice, the “commonly used” languages are those widely adopted for machine learning, deep learning, and AI research pipelines. Popular choices include keywordPython and keywordJava, and historically influential keywordLISP. Logic-programming languages like keywordProlog are also used in specific AI subareas (e.g., rule-based reasoning).

Given the options:

  • (i) Prolog — used in some AI (especially logic/rule reasoning), though not as mainstream as Python.
  • (iii) LISP — historically important and still appears in AI-related contexts.
  • (ii) Java — commonly used in AI engineering and production systems.
  • (iv) Perl — generally not considered a commonly used language for mainstream AI compared with Java/LISP/Prolog.

Therefore, the best answer is (iv) Perl.

To connect this with a “most commonly used” viewpoint: AI/ML ecosystems are dominated by mainstream languages and libraries; Java and Python are frequently cited in AI/ML tooling discussions, while Perl is not commonly listed as a primary AI language in the same way.

Programming Languages for AI / ML (overview)

"How to reason about “commonly used”

For MCQs, treat “commonly used” as “widely adopted for AI/ML development and research ecosystems,” not just “used somewhere in AI.” Languages like Python/Java dominate toolchains; older or niche languages (or scripting languages) are less likely to be labeled “commonly used.”

"Common vs. historically important

A language can be historically important (e.g., LISP) yet still not be the most used today. MCQs usually ask “commonly used” in practice, so you must separate ‘used in AI at some point’ from ‘commonly used for AI today.’

Decide the best answer among the options

  1. 1
    Step 1

    Read it as “frequently used in AI/ML development and ecosystems,” not merely “appears in AI literature.”

  2. 2
    Step 2

    Java is used broadly in software engineering and AI-related production tooling; LISP is strongly tied to early AI; Prolog is tied to logic/rule reasoning.

  3. 3
    Step 3

    Perl is a scripting language and is not typically listed among the primary languages used for AI/ML training frameworks and mainstream AI development.

  4. 4
    Step 4

    Choose (iv) Perl as the best answer.

AI Programming Language Influence (high-level)

LISP

Early AI era

Strong association with early AI research and symbolic reasoning."

Prolog

Rule-based / logic programming

Used for knowledge representation and logical inference."

Java

Production and enterprise systems

Common in large-scale software engineering; used in AI systems and tooling."

Perl

General scripting

Less commonly used as a primary AI/ML development language."
