File operations and Exceptions
Essential Python notes covering file operations (read, write, append), exception handling (try-except for multiple errors), and object serialization with the pickle module. Includes clear, practical programs with expected outputs.
Description
provide a practical guide to handling data and errors in Python by covering three core pillars: File Operations (methods for creating, reading, writing, and appending text and binary files) , Exception Handling (using try-except blocks to prevent crashes from common errors like division by zero or missing files) , and Pickling (using the pickle module to serialize and save complex objects like lists and dictionaries into bytes, and load them back later). Every concept is supported by a short program and its expected terminal output.
