Prepare for the Hackerrank - HackerRank Python Certification exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: Which of the following statements about the `collections.deque` object in Python is true?
Answer: D. It provides O(1) time complexity for append and pop operations from both ends.
Explanation:
The correct answer is that collections.deque gives O(1) time for append and pop operations at both ends. It is a double-ended queue built so that adding or removing at either end does not require shifting other elements.
The O(n) option is wrong because that cost is what a plain list pays when you insert or pop at the left end, since every other element has to move. The immutable option is wrong because a deque is mutable and you change it all the time with append, pop and extend. The random access option is wrong because a deque is built for its ends; reaching into the middle is slower than indexing a list.
Rule to remember: use a deque when you add or remove at both ends, such as queues and sliding windows, and use a list when you mostly index by position.
Question: Which Python feature would most likely be tested in the OOP section of a HackerRank Python (Intermediate) certification?
Answer: B. Implementing inheritance and method overriding
Explanation:
The correct answer is implementing inheritance and method overriding. These are central object-oriented ideas: a child class reuses behaviour from a parent class and replaces a method with its own version when needed.
Type hints are wrong because they are an annotation feature, useful but not specific to object-oriented design. F-strings are wrong because they are a string formatting feature and belong with text handling. Importing the math module is wrong because it is about using a library, not about structuring code with classes.
Rule to remember: when a question mentions the object-oriented section, think about classes, constructors, inheritance, overriding, and how methods are looked up on an object. Features that do not involve classes are usually distractors.
Question: What does `enumerate(['a', 'b', 'c'], start=1)` produce?
Answer: A. (1,'a'), (2,'b'), (3,'c')
Explanation:
The correct answer is (1,'a'), (2,'b'), (3,'c'). The enumerate function pairs each item with a counter, and the start argument sets where that counter begins. With start=1 the counter begins at 1.
The option beginning at 0 is wrong because it shows the default behaviour, which applies only when you do not pass start. The plain list of letters is wrong because enumerate adds the counter and does not return the items alone. The option with only numbers is wrong because it drops the original items.
Rule to remember: enumerate yields pairs of counter and item, the counter defaults to 0, and start changes only the counter, never the items. Also remember it returns an iterator, so wrap it in list() to see all pairs at once.
Begin with the official HackerRank skills verification page for Python (Basic) so you know the format: 2 questions, solved in the online IDE. Then check your starting point with the Hackerrank Python Basics set and note which topics feel slow.
Work through the topic sets in turn. Cover scalar types and operators, control flow and looping, functions, and string methods. Then move to collections and data structures and data structures and algorithms.
After each set, read the explanation for every question you missed and write a short note on the rule behind it. Then open an editor and write a small program that uses that rule, because the real test asks you to code, not to select an answer.
Near test day, use Hackerrank Preparation Tips, redo the sets you found hardest, and practise solving a problem start to finish in a browser editor. If you need to retake, remember the 30 day wait and use it to target weak topics.
Earning a HackerRank certificate requires only your time and effort. It is a high-value credential with no financial cost for developers. Practice with the free HackerRank Python Certification practice test on PracticeTestGeeks (7 questions with answer explanations).

A software engineer with a HackerRank Python certification is negotiating a salary increase. What is the MOST effective way to leverage the certification?
Answer: B. Use it as evidence of validated, measurable Python proficiency to justify a higher pay band
Presenting a certification as documented proof of skill level strengthens salary negotiation by providing an objective benchmark.
Which Python feature would most likely be tested in the OOP section of a HackerRank Python (Intermediate) certification?
Answer: B. Implementing inheritance and method overriding
Inheritance and method overriding are core OOP concepts tested in intermediate-level Python certifications.
Which Python career path is LEAST likely to list a HackerRank Python certification as a differentiator in job postings?
Answer: D. Embedded systems firmware engineer using C
Embedded firmware roles primarily require C/C++ and hardware knowledge, making Python certification largely irrelevant to that career path.
Approximately how many coding challenges are included in the HackerRank Python (Basic) certification exam?
Answer: B. 3–4 challenges
The Python Basic certification typically contains 3–4 coding challenges to be completed within the time limit.
