Top Python Interview Questions for Freshers

Now, let’s go through the frequently asked Python Interview Questions for Freshers:

What is Python? Explain its key features.

Python is a high-level, interpreted programming language known for its simplicity and readability.

Key features include:

• Interpreted and dynamically typed.
• Object-oriented and supports functional programming.
• Extensive libraries for various applications.
• Platform-independent (write once, run anywhere).

What are Python’s data types?

Python offers several built-in data types, such as:

• Numeric: int, float, complex
• Sequence: str, list, tuple, range
• Mapping: dict
• Set types: set, frozenset
• Boolean: bool
• Binary types: bytes, byte array, memory view

What are Python lists, and how are they different from tuples?

• Lists are mutable, meaning their elements can be changed. They are created using square brackets, e.g., [1, 2, 3].
• Tuples are immutable, meaning they cannot be altered once defined. They are created using parentheses, e.g., (1, 2, 3).

Explain Python’s pass statement.

The pass statement acts as a placeholder in Python. It allows code to run without operation when a statement is syntactically required. For example:

def my_function(): pass

What is a Python dictionary?

A dictionary in Python is an unordered collection of key-value pairs, defined using curly braces {}. For example:

my_dict = {“name”: “John”, “age”: 25}

Dictionaries allow quick data retrieval using keys.

What are Python’s key advantages over other languages?

• Simple and readable syntax.
• Vast library support.
• Strong community backing.
• Cross-platform compatibility.
• Excellent for both scripting and full-scale application development.

What are Python functions, and why are they important?

Functions in Python are blocks of reusable code that perform specific tasks. They improve code modularity and reduce redundancy.

Example:

def greet(name): return f”Hello, {name}!”

Differentiate between shallow copy and deep copy in Python.

• Shallow Copy: Creates a new object but copies references to the original objects inside it. Use copy.copy() for this.
• Deep Copy: Copies the object and the objects inside it, creating independent objects. Use copy.deepcopy().

What are Python decorators?

Decorators are special functions that modify the behavior of other functions or methods. They are often used in scenarios like logging or validation.

Example:

def decorator(func):
def wrapper():
print(“Function is being called”)
func()
return wrapper

@decorator
def say_hello():
print(“Hello!”)

say_hello()

What is Python’s GIL (Global Interpreter Lock)?

The Global Interpreter Lock (GIL) is a mutex in CPython that allows only one thread to execute at a time, even in multi-threaded applications. This ensures thread safety but limits concurrency in CPU-bound processes.

Python Coding Questions for Freshers

Now, let’s look at some of the commonly asked Python Coding questions:

Write a program to check if a number is prime.

Write a Python program to reverse a string.

How would you find the largest element in a list?

FAQs on Python Interview Questions for Freshers

What are the key features of Python?

Python features include interpreted language, dynamically typed, object-oriented programming support, extensive libraries, platform independence, and simple, readable syntax.

Explain lists vs. tuples in Python.

Lists are mutable, use square brackets [], and can be modified. Tuples are immutable, use parentheses (), and can’t be changed after creation.

What are Python data types?

Core data types include int, float, str, bool, list, tuple, dict, and set. Each type has specific properties and methods for data manipulation.

How does Python handle memory management?

Python uses automatic memory management with garbage collection. Objects are automatically deallocated when no references to them exist.

What is list comprehension?

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].

Explain inheritance in Python.

A: Inheritance allows a class to inherit attributes/methods from another class. Python supports single, multiple, and multilevel inheritance.

What are decorators in Python?

Decorators are functions that modify other functions’ behavior. They use @symbol syntax and are commonly used for logging, validation, and timing.

How to handle exceptions in Python?

Use try-except blocks. try contains code that might raise exceptions, except handles errors,and finally executes regardless of exceptions.

What is PIP in Python?

PIP (Package Installer for Python) is Python’s package manager. It installs and manages additional libraries and dependencies.

Explain Python’s range() function.

range() generates a sequence of numbers. Takes start, stop, step parameters. Commonly used in loops: range(5) produces 0,1,2,3,4.

What are Python modules and packages?

Modules are single Python files containing code. Packages are directories containing multiple modules and an init.py file.

How to handle file operations in Python?

Use the open() function with modes (r,w,a). Use with statement for automatic file closing: with open(‘file.txt’, ‘r’) as f.
