float() — Python Technical Interview Questions & Answers

float()

float()

  • float() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • float() — output: 4.5. String became float.
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix float up with a similar name (sorted vs sort, int vs float).

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