5 Questions
- Q1. What is the difference between list and tuples ?
- Ans.
Lists are mutable while tuples are immutable in Python.
Lists use square brackets [] while tuples use parentheses ().
Elements in a list can be added, removed, or modified while tuples cannot be modified.
Lists are used for collections of homogeneous items while tuples are used for heterogeneous items.
Lists are slower than tuples in terms of performance.
Example: my_list = [1, 2, 3] and my_tuple = (4, 'hello', True)
- Q2. What is pep 8 ?
- Ans.
PEP 8 is a style guide for Python code.
PEP stands for Python Enhancement Proposal.
PEP 8 provides guidelines for writing readable and maintainable Python code.
It covers topics such as naming conventions, code layout, and programming practices.
Examples include using snake_case for variable names and indenting with four spaces.
Adhering to PEP 8 can make code more consistent and easier to understand for other developers.
- Q3. What is namespace in python ?
- Ans.
Namespace is a way to organize code and avoid naming conflicts in Python.
Namespaces are implemented as dictionaries.
Python uses namespaces to support modularity and avoid naming conflicts.
Namespaces can be nested within other namespaces.
The global namespace is the namespace that is visible throughout the entire program.
The local namespace is the namespace that is visible only within a particular function or code block.
- Q4. What is lambda expression ?
- Ans.
Lambda expression is a concise way to represent anonymous functions in programming languages.
Lambda expressions are used to create functions without a name.
They are often used in functional programming languages.
Lambda expressions can be used to pass functions as arguments to other functions.
They can also be used to create closures, which are functions that capture variables from their surrounding environment.
Lambda ex...
- Q5. What is pickling and unpickling ?
- Ans.
Pickling is the process of converting a Python object into a byte stream, while unpickling is the reverse process.
Pickling is used to store Python objects in a file or transfer them over a network.
The pickle module in Python is used for pickling and unpickling.
The pickled file can be opened in any Python environment and the object can be retrieved.
Unpickling can also be used to create a deep copy of an object.

- Q1. Hashmap working
- Ans.
Hashmap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.
Hashmap uses a hashing function to map keys to indices in an array.
It allows for constant time complexity O(1) for insertion, deletion, and retrieval operations.
Example: HashMap<String, Integer> map = new HashMap<>(); map.put("key", 123); int value = map.get("key");

- Q2. Array list vs Linked List
- Ans.
Array list is faster for accessing elements by index, while Linked List is better for frequent insertions and deletions.
Array list has constant time access to elements by index, while Linked List requires traversing the list to find an element.
Linked List is better for frequent insertions and deletions as it only requires changing pointers, while Array list may require shifting elements.
Array list uses contiguous memor...

- Q1. Polymorphism in C++
- Ans.
Polymorphism in C++ allows objects of different classes to be treated as objects of a common superclass.
Polymorphism is achieved through function overloading and virtual functions.
Function overloading allows multiple functions with the same name but different parameters.
Virtual functions are functions in a base class that are overridden in derived classes.
Example: Animal class with virtual function 'makeSound', Cat and
- Q2. Standard template library in C++
- Ans.
STL in C++ provides reusable algorithms and data structures for efficient programming.
STL includes containers like vector, list, map, algorithms like sort, find, and iterators.
Example: vector
v = {1, 2, 3}; sort(v.begin(), v.end()); STL saves time by providing pre-implemented solutions for common programming tasks.
- Q3. Design Patterns in C++
- Ans.
Design patterns in C++ are reusable solutions to common problems in software design.
Design patterns help in creating flexible, maintainable, and scalable code.
Examples of design patterns in C++ include Singleton, Factory, Observer, and Strategy.
Each design pattern has a specific purpose and can be applied in different scenarios.
Understanding design patterns can improve code quality and efficiency in software developmen
