Polyglot C-Python File Creation

This skill provides guidance for creating single source files that function correctly as both Python and C programs.

When to Use

This skill applies when:

• Creating a file that must be valid syntax for both Python and C
• The file needs to execute correctly under both python filename and gcc filename && ./output
• Building polyglot programs that produce equivalent output in both languages

Polyglot Structure Approach

Core Technique

Use preprocessor directives and string literals to hide language-specific code:

1. Hide C code from Python: Wrap C-specific code in triple-quoted strings that Python ignores
2. Hide Python code from C: Use #if 0...#endif preprocessor blocks that C ignores but Python sees as comments
