- Python interviews test basics first: data types, functions, loops, lists, tuples, dictionaries, and indentation.<\/li>\n\n\n\n
- Intermediate questions focus on file handling, exceptions, list comprehension, lambda functions, and coding logic.<\/li>\n\n\n\n
- Advanced rounds cover decorators, generators, GIL, memory management, async programming, and scalable project structure.<\/li>\n\n\n\n
- Interviewers check syntax, logic, debugging, performance, and clean code thinking.<\/li>\n\n\n\n
- Best preparation comes from practicing code, understanding concepts, and revising all difficulty levels.<\/li>\n<\/ul>\n\n\n\n
If you’re just starting your Python journey or preparing for your first tech interview, this section is for you. These questions cover the basics, from data types and syntax to simple coding exercises, and are often asked to gauge how well you understand Python\u2019s core concepts. Mastering these is your first step to building a solid foundation.<\/p>\n\n\n\n

Most Python interviews test the same core: syntax fluency, data structures, and how you think through edge cases out loud. Recruiters at Indian product companies and FAANG offices now expect candidates to write runnable code, not just describe concepts. This guide is trimmed to the questions that actually come up, grouped by experience level so you can focus your prep.<\/p>\n\n\n\n
Fresher-Level Python Interview Questions<\/strong><\/h2>\n\n\n\n
1. What is Python?<\/strong><\/h3>\n\n\n\n
![\"What](\"https:\/\/www.guvi.in\/blog\/wp-content\/uploads\/2025\/05\/What-is-Python_-1200x628.webp\" "\\"\\"")
<\/figure>\n\n\n\nPython<\/a> is an interpreted, object-oriented, high-level, general-purpose programming language with dynamic semantics. The implementation of Python was started in December 1989 by Guido Van Rossum at CWI in the Netherlands.<\/p>\n\n\n\n
In February 1991, he published the code to alt. sources. Furthermore, in 1994, Python 1.0 was released.<\/p>\n\n\n\n
print(\"Hello, Python\") # runs top to bottom, no compilation step needed<\/code><\/pre>\n\n\n\n2. What are the key features of Python?<\/strong><\/h3>\n\n\n\n

<\/figure>\n\n\n\nDevelopers love Python for a few solid reasons:<\/p>\n\n\n\n
- \n
- Simplicity & Readability<\/strong>: The syntax is clear and resembles English, making it beginner-friendly.<\/li>\n\n\n\n
- Interpreted Language<\/strong>: Python executes lines one by one, which simplifies debugging.<\/li>\n\n\n\n
- Dynamically Typed<\/strong>: You don\u2019t need to declare variable types; Python figures it out.<\/li>\n\n\n\n
- Cross-Platform Compatibility<\/strong>: Write once, run anywhere (Windows, Linux, Mac).<\/li>\n\n\n\n
- Large Standard Library<\/strong>: You get modules for math, file I\/O, JSON, OS-level operations, and more out of the box.<\/li>\n<\/ul>\n\n\n\n

3. Difference between
is<\/code> and==<\/code>?<\/strong><\/h3>\n\n\n\n==<\/code> checks value equality,is<\/code> checks identity (same memory object).<\/p>\n\n\n\na = [1, 2]\nb = [1, 2]\nprint(a == b) # True\nprint(a is b) # False<\/code><\/pre>\n\n\n\n4. How do you write a function? <\/strong><\/h3>\n\n\n\n
def add(a, b):\n return a + b\nprint(add(3, 5)) # 8<\/code><\/pre>\n\n\n\n5. What are Python’s built-in data types?<\/strong> <\/h3>\n\n\n\n
int, float, str, bool, list, tuple, dict, set \u2014 each is an object with its own methods.<\/p>\n\n\n\n

6. How do you check membership in a list?<\/strong> <\/h3>\n\n\n\n
fruits = [\"apple\", \"banana\"]\nprint(\"banana\" in fruits) # True<\/code><\/pre>\n\n\n\n7. Why is indentation important?<\/strong><\/h3>\n\n\n\n
Python uses whitespace, not braces, to define code blocks. Standard is 4 spaces.<\/p>\n\n\n\n
8. How do you handle user input?<\/strong><\/h3>\n\n\n\n
age = int(input(\"Enter age: \")) # input() always returns a string, cast as needed<\/code><\/pre>\n\n\n\n9. What are
*args<\/code> and**kwargs<\/code>?<\/strong> <\/h3>\n\n\n\ndef total(*args, **kwargs):\n return sum(args), kwargs\nprint(total(1, 2, 3, name=\"Kiran\")) # (6, {'name': 'Kiran'})<\/code><\/pre>\n\n\n\n10. Explain list comprehension.<\/strong> <\/h3>\n\n\n\n
squares = [x**2 for x in range(5) if x % 2 == 0] # [0, 4, 16]<\/code><\/pre>\n\n\n\nSenior-Level Python Interview Questions <\/strong><\/h2>\n\n\n\n

with open(\"data.txt\", \"r\") as f:\n content = f.read() # auto-closes file<\/code><\/pre>\n\n\n\n14.
append()<\/code> vsextend()<\/code>?<\/strong> <\/h3>\n\n\n\nappend()<\/code> adds one item (even a list, as a single element);extend()<\/code> unpacks and adds each item.<\/p>\n\n\n\na = [1, 2]\na.extend([3, 4]) # [1, 2, 3, 4]<\/code><\/pre>\n\n\n\n15. What are decorators, and why use them?<\/strong> <\/h3>\n\n\n\n
Decorators wrap a function to add behavior \u2014 logging, timing, auth \u2014 without touching its source.<\/p>\n\n\n\n
def logger(func):\n def wrapper(*a, **kw):\n print(\"Called:\", func.__name__)\n return func(*a, **kw)\n return wrapper\n\n@logger\ndef greet(): print(\"Hi\")<\/code><\/pre>\n\n\n\nPython OOP Interview Questions with Code Examples<\/strong><\/h2>\n\n\n\n

self<\/code>?<\/strong><\/h3>\n\n\n\nA reference to the current instance, used to access its attributes and methods inside the class.<\/p>\n\n\n\n
18.
staticmethod<\/code> vsclassmethod<\/code>?<\/strong> <\/h3>\n\n\n\nclass Utils:\n @staticmethod\n def add(a, b): return a + b # no instance\/class access needed\n\n @classmethod\n def create(cls): return cls() # receives the class itself as 'cls'<\/code><\/pre>\n\n\n\n19. What are magic (dunder) methods?<\/strong> <\/h3>\n\n\n\n
Special methods like
__str__<\/code>,__len__<\/code>,__eq__<\/code> that let your objects work with built-in syntax.<\/p>\n\n\n\nclass Point:\n def __init__(self, x, y): self.x, self.y = x, y\n def __eq__(self, other): return self.x == other.x and self.y == other.y<\/code><\/pre>\n\n\n\n20. What is Method Resolution Order (MRO)?<\/strong><\/h3>\n\n\n\n
- Interpreted Language<\/strong>: Python executes lines one by one, which simplifies debugging.<\/li>\n\n\n\n
- Python remains the No. 1 language<\/strong> on the TIOBE Index in 2026.<\/li>\n
