PCEP Computer Programming and Python Fundamentals Practice Question
Which TWO statements correctly describe Python's dynamic typing?
⚠ Common exam trap
The PCEP exam often tests the misconception that dynamic typing means a variable's type is fixed after first assignment, or that type checking happens at compile time, leading candidates to incorrectly select Option C or B.

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
✓
The interpreter infers the type from the assigned value.
Python's dynamic typing means the interpreter determines the type of a variable at runtime based on the value assigned to it. You do not need to declare the type explicitly; the type is inferred from the object the variable references.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Variable types must be declared before use.
Why it's wrong here
Python does not require type declarations.
- ✗
Python checks types only at compile time.
Why it's wrong here
Python is dynamically typed; type checking occurs at runtime.
- ✗
A variable's type is fixed once assigned.
Why it's wrong here
The variable can be reassigned to a value of a different type.
- ✓
The interpreter infers the type from the assigned value.
Why this is correct
The type is determined by the object assigned to the variable.
- ✓
The type of a variable can change at runtime.
Why this is correct
Dynamic typing allows rebinding a variable to a different type.
