The effect of Perl modules are usually limited to the current scope in which it was loaded. It is common for Perl modules to have embedded documentation in Perl's Plain Old Documentation format. POD imposes little structure on the author. It is flexible enough to be used to write articles, web pages and even entire books such as Programming Perl.
The path length of a simple conditional instruction would normally be considered as equal to 2, [citation needed] one instruction to perform the comparison and another to take a branch if the particular condition is satisfied. The length of time to execute each instruction is not normally considered in determining path length and so path length ...
In a talk at the YAPC::Europe 2005 conference and subsequent article "A Timely Start", Jean-Louis Leroy found that his Perl programs took much longer to run than expected because the perl interpreter spent significant time finding modules within his over-large include path. [120] Unlike Java, Python, and Ruby, Perl has only experimental support ...
The Perl Object Environment (POE) is a library of Perl modules written in the Perl programming language by Rocco Caputo et al. . From CPAN: "POE originally was developed as the core of a persistent object server and runtime environment.

Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
This comparison of programming languages compares how object-oriented programming languages such as C++, Java, Smalltalk, Object Pascal, Perl, Python, and others manipulate data structures. Object construction and destruction
A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
