How do you iterate over a list and pull element indices at the same time?
Interviewer Expectations for this Question
01
Core Competency
Assesses fundamental understanding of Python conventions, runtime behavior, and memory/performance considerations.
02
Evaluation Criteria
Hiring managers look for precision, avoidance of ambiguous jargon, and ability to explain trade-offs under real production conditions.
Comprehensive Model Answer
Verified Solution
You are looking for the enumerate function. It takes each element in a sequence
(like a list) and sticks it's location right before it. For example:
>>>my_list=['a','b','c']
>>>list(enumerate(my_list))
[(0,'a'),(1,'b'),(2,'c')]
Note that enumerate() return s an object to be iterated over, so wrapping it in list() just
helps us see what enumerate() produces.
An example that directly answers the question is given below
my_list=['a','b','c']
fori,charinenumerate(my_list):
printi,char
The output is:
0a
1b
2c
Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
