Скачать или смотреть Python Standard Library Part II: Advanced Modules for Professional Programming

This video dives into Chapter 11 of the Python Tutorial (Release 3.7.0), offering a brief tour of advanced modules in Python's Standard Library. These modules are crucial for professional programming needs and cover functionalities such as:
• Output Formatting: Learn about reprlib, pprint, textwrap, and locale for sophisticated control over displaying data and text.
• Templating: Discover the string.Template class for creating user-customizable applications by separating program logic from output details.
• Working with Binary Data Record Layouts: Explore the struct module for packing and unpacking variable-length binary record formats.
• Multi-threading: Understand how the threading module helps decouple tasks, improve application responsiveness, and manage I/O in parallel with computations. This section also touches upon queue for safer inter-thread communication.
• Logging: Get an overview of the logging module, a flexible system for sending messages to various outputs like files or sys.stderr, with different priority levels (DEBUG, INFO, WARNING, ERROR, CRITICAL).
• Weak References: Learn about the weakref module for tracking objects without creating persistent references, useful for caching expensive-to-create objects.
• Tools for Working with Lists: Explore specialized data structures like array.array for homogeneous data storage and collections.deque for efficient appends and pops from both ends. You'll also see functions from bisect for sorted lists and heapq for heap-based operations.
• Decimal Floating Point Arithmetic: Understand the decimal module for exact decimal representation and precise arithmetic, crucial for financial applications and avoiding common floating-point issues.
This chapter demonstrates how Python's "batteries included" philosophy provides robust capabilities for various programming challenges.
