PCEP Practice Question: Data Types, Variables, Basic I/O and Operators

What is the result of bool(0) in Python?

⚠ Common exam trap

Python Institute often tests the misconception that bool(0) returns 0 or None, exploiting candidates who confuse the integer value 0 with the Boolean False, or who think that only the literal False keyword is falsy.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

False

The bool() function in Python converts any value to a Boolean. The integer 0 is considered a falsy value, so bool(0) returns False. This is because Python defines 0, None, empty collections, and False itself as falsy.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • 0

    Why it's wrong here

    bool(0) returns a boolean, not integer.

  • None

    Why it's wrong here

    bool never returns None.

  • True

    Why it's wrong here

    0 is falsy, so bool returns False.

  • False

    Why this is correct

    Correct; 0 is falsy.
