slice() — Python Technical Interview Questions & Answers

slice()

slice()

  • slice() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • slice() — output: [20, 30]. slice(1,3) same as [1:3].
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix slice up with a similar name (sorted vs sort, int vs float).

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

Code Examples for slice()

Example

# slice()
a = [10, 20, 30, 40]
print(a[slice(1, 3)])

slice() — output: [20, 30]. slice(1,3) same as [1:3].
