range() — Python Technical Interview Questions & Answers

range()

range()

  • range() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • range() — output: [1, 2, 3, 4]. Stop 5 is exclusive.
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix range up with a similar name (sorted vs sort, int vs float).

Technical Interview Tip: Call range() once and say what prints.

Code Examples for range()

Example

# range()
print(list(range(1, 5)))
