<\/span><\/h2>\n\n\n\nWhat are the key features of Python?<\/h3>\n\n\n\n
Python features include interpreted language, dynamically typed, object-oriented programming support, extensive libraries, platform independence, and simple, readable syntax.<\/p>\n\n\n\n
Explain lists vs. tuples in Python.<\/h3>\n\n\n\n
Lists are mutable, use square brackets [], and can be modified. Tuples are immutable, use parentheses (), and can’t be changed after creation.<\/p>\n\n\n\n
What are Python data types?<\/h3>\n\n\n\n
Core data types include int, float, str, bool, list, tuple, dict, and set. Each type has specific properties and methods for data manipulation.<\/p>\n\n\n\n
How does Python handle memory management?<\/h3>\n\n\n\n
Python uses automatic memory management with garbage collection. Objects are automatically deallocated when no references to them exist.<\/p>\n\n\n\n
What is list comprehension?<\/h3>\n\n\n\n
List comprehension is a concise way to create lists using a single line of code. Example: [x*2 for x in range(5)] creates [0,2,4,6,8].<\/p>\n\n\n\n
Explain inheritance in Python.<\/h3>\n\n\n\n
A: Inheritance allows a class to inherit attributes\/methods from another class. Python supports single, multiple, and multilevel inheritance.<\/p>\n\n\n\n
What are decorators in Python?<\/h3>\n\n\n\n
Decorators are functions that modify other functions’ behavior. They use @symbol syntax and are commonly used for logging, validation, and timing.<\/p>\n\n\n\n
How to handle exceptions in Python?<\/h3>\n\n\n\n
Use try-except blocks. try contains code that might raise exceptions, except handles errors,and finally executes regardless of exceptions.<\/p>\n\n\n\n
What is PIP in Python?<\/h3>\n\n\n\n
PIP (Package Installer for Python) is Python’s package manager. It installs and manages additional libraries and dependencies.<\/p>\n\n\n\n
Explain Python’s range() function.<\/h3>\n\n\n\n
range() generates a sequence of numbers. Takes start, stop, step parameters. Commonly used in loops: range(5) produces 0,1,2,3,4.<\/p>\n\n\n\n
What are Python modules and packages?<\/h3>\n\n\n\n
Modules are single Python files containing code. Packages are directories containing multiple modules and an init.py file.<\/p>\n\n\n\n
How to handle file operations in Python?<\/h3>\n\n\n\n
Use the open() function with modes (r,w,a). Use with statement for automatic file closing: with open(‘file.txt’, ‘r’) as f.<\/p>\n","protected":false},"excerpt":{"rendered":"
