What is a .PYM file?
The file extension .PYM refers to a PYM Macro Preprocessor File. This type of file is associated with PYM, a macro preprocessor that utilizes the Python programming language. A .PYM file contains macros, which are essentially shortcuts or automated sequences that can perform tasks within a program. These macros are specifically defined within the file between markers labeled "#begin python" and "#end python." These macro files are particularly useful for programmers because they allow the creation of shortcuts that can automate repetitive tasks or complex function calls. This helps in making the coding process more efficient and less error-prone.
To open a .PYM file, you can use the PYM program itself, which is designed to handle these specific types of files. Additionally, since .PYM files are essentially text-based, they can also be opened using basic text editing software. For Windows users, Microsoft Notepad can be used, which is included with the operating system. Similarly, for macOS users, Apple TextEdit can be used, which is also included with the operating system. Other general text editors capable of opening plain text files can also be used to view and edit .PYM files.
During the preprocessing stage of the Python interpreter, the macros stored in the .PYM files are expanded into their full text replacements. This means that the shortcuts defined in the .PYM file are converted into the longer, more complex code they represent, right before the Python program is actually run. This preprocessing helps in streamlining the execution of Python scripts by automating certain parts of the code.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
