Python Interview Questions for Freshers: Part - 1
1. What is Python?
Python, recognized for its simplicity and readability, operates as a high-level, interpreted programming language. It supports multiple programming paradigms and is widely used in various domains like web development, data analysis, artificial intelligence, and more.
2. What is a dynamically typed language?
In a dynamically typed language like Python, variable types are not explicitly declared. Instead, the type of a variable is interpreted during execution, allowing more flexibility but potentially leading to runtime errors if types are incompatible.
3. What is an Interpreted language?
An interpreted language, like Python, executes instructions directly without prior compilation. The interpreter reads and executes the code line by line, translating it to machine code or an intermediate representation on the fly.
4. What does PEP 8 entail, and what significance does it hold in programming?
PEP 8 is a style guide for Python code. It offers guidelines on how to format and structure code for better readability and consistency. Adhering to PEP 8 improves code maintainability, readability, and collaboration among developers.
5. What is Scope in Python?
Scope defines the visibility and accessibility of variables within a program. In Python, variables can have global, local, or nonlocal scope, determining where they can be accessed or modified.
6. What are lists and tuples? What is the key difference between the two?
Both lists and tuples belong to the sequence data types within Python. Lists are mutable (modifiable), denoted by square brackets, while tuples are immutable (unchangeable), denoted by parentheses. This means tuples cannot be altered after creation, whereas lists can be modified.
7. What are the common built-in data types in Python?
Python includes various built-in data types such as integers, floating-point numbers, strings, lists, tuples, dictionaries, and sets, among others, each serving different purposes and functionalities.
8. What is pass in Python?
‘pass’ is a keyword in Python used as a placeholder for syntactical purposes. It serves as a null operation, indicating that no action needs to be taken, primarily used when a statement is syntactically required but no action is necessary.
9. What are modules and packages in Python?
Modules are individual Python files that contain functions, variables, and classes. Packages are a collection of related modules organized in directories. They help in organizing and reusing code across different Python projects.
10. What are global, protected, and private attributes in Python?
Global attributes are accessible from anywhere in the code, while protected attributes are conventionally marked by a single underscore (_) indicating that they should not be accessed directly. Private attributes, denoted by double underscores (__) are meant to be inaccessible outside their class in Python.
In conclusion,
Python interview questions offer a solid foundation for freshers. Embracing these concepts ranging from basics to essential libraries—equips newcomers to confidently tackle interviews and embark on a successful Python-oriented career journey. With practice and understanding, mastering these fundamentals becomes a stepping stone to thriving in the programming landscape.
