Question 455 of 498
PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
A developer wants to assign the value 3.14 to a variable and later change it to the integer 3. Which of the following is true?
⚠ Common exam trap
Many exam-takers confuse Python's dynamic typing with static typing rules from languages like Java or C, leading them to believe that type changes require explicit conversion or are disallowed.
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
✓
This is allowed because Python is dynamically typed.
Python is dynamically typed, meaning variables can be reassigned to values of any type at runtime. The developer can first assign the float 3.14 to a variable and later reassign the integer 3 to the same variable without any type declaration or conversion function required.

No declaration needed.
- ✗
This causes a TypeError because you cannot change types.
Why it's wrong here
Python allows type changes.
- ✓
This is allowed because Python is dynamically typed.
