Python coding questions span a wide range of difficulties from beginner basics to advanced algorithmic challenges, often categorized by level. Beginner questions typically involve fundamental operations like calculating factorials, checking for even/odd numbers, or generating dictionaries of squares. Intermediate problems require handling data structures such as lists and tuples, sorting words, or solving mathematical formulas like the Q equation. Advanced questions focus on complex algorithms including dynamic programming (Longest Increasing Subsequence), backtracking (N-Queens, Parentheses), and data structure implementations (Trie, Queue using stacks).
Common topics frequently tested in interviews include:
Data Structures: Converting lists to tuples, removing duplicates, and finding intersections of arrays.
String Manipulation: Checking palindromes, counting vowels, reversing strings, and capitalizing words.
Algorithms: Implementing sorting, recursion for power calculation, and finding prime numbers.
Object-Oriented Programming: Defining classes with methods like
getStringandprintStringto handle input/output.
Resources such as GeeksforGeeks, HackerRank, and CodeChef provide extensive practice problems with solutions, while platforms like LeetCode and InterviewBit offer specific interview-focused coding challenges. Level 1 exercises can often be solved with one or two functions, whereas Level 3 problems demand the use of rich libraries, advanced data structures, and complex algorithms.

Here are some easy ones:
- What are Python decorators and how would you use them?
- How do you debug your Python code?
- How would you setup many projects where each one uses different versions of Python and third party libraries?
- Do you follow PEP8 while writing your code?
How about something involving Python list comprehensions? To me, those were one of the big selling points over C++, after I read about them in Dive into Python.
"Write a list comprehension that builds a list of the even numbers from 1 to 10 (inclusive)".
Where the answer is anything like this (note the range values avoid a fencepost error):
foo = [x for x in range(1, 11) if (x % 2) == 0]
print foo
[2, 4, 6, 8, 10]
For that matter, if you understand all the concepts listed in Dive into Python, that should cover most of the important features.
Title.
I've never been though it before and don't know what to expect.
What is it usually about? OOP? Dicts, lists, loops, basic stuff? Algorithms?
If you have any leetcode question or if you remember some from your exeperience, please share!
