The Philosophy of Execution and the Interpreter in Python At the surface of a language, there is syntax and structure; at the deeper level, there is execution and time. The execution model of Python is not a technical detail, but a reflection of the language’s philosophy. It determines how Python understands code, how it constructs … Read more

During the process of learning Python programming, acquiring some interesting facts or understanding the underlying principles can help you gain a deeper understanding of the language. Python Metaclasses: Metaclasses are the “classes” that create classes. Although metaclasses are not commonly used in everyday programming, understanding how they work can assist you in creating custom class … Read more
Exclusive: Python Bytecode Analysis, Interpreter Execution Principles, and Performance Optimization At three o’clock that morning, I was still debugging a bizarre performance issue. The code logic was not complex, but the execution efficiency was absurdly low. The coffee had gone cold. I sighed. In my eight years of Python development, I have experienced similar situations … Read more
Incremental Assignment of Sequences The behavior of the incremental assignment operators += and *= depends on their first operand. For simplicity, we will focus on incremental addition (+=), but these concepts apply equally to *= and other incremental operators. The special method behind += is iadd (used for “in-place addition”). However, if a class does … Read more
Discuss common types of Python questions. One The first type: Direct Decompilation Type In addition to directly obtaining the Python file for the question, the question setter can also slightly modify it by providing the corresponding .pyc file, which is the bytecode of Python. Definition of PYC File PYC files are the main intermediate files … Read more
