20+ practice questions focused on Data Types, Variables, Basic I/O and Operators — one of the most tested topics on the Certified Entry-Level Python Programmer PCEP exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Data Types, Variables, Basic I/O and Operators PracticeA developer writes the following code: x = 5; y = 2; print(x // y). What is the output?
Explanation: The floor division operator (//) in Python returns the largest integer less than or equal to the result of the division. Since 5 divided by 2 equals 2.5, the floor is 2, and the result is an integer (int) because both operands are integers. Therefore, the output is 2.
A junior developer writes: x = 10; y = 3; print(x % y). What will be printed?
Explanation: The modulo operator (%) returns the remainder of the division of the left operand by the right operand. Here, 10 divided by 3 equals 3 with a remainder of 1, so print(x % y) outputs 1.
A developer needs to convert a string '25' to an integer and then add 10. Which code correctly performs this?
Explanation: Option A is correct because `int('25')` converts the string '25' to the integer 25, and then `+ 10` performs integer addition, resulting in 35. The `print()` function outputs the result. This follows Python's type conversion rules where explicit conversion is required to combine a string and an integer in arithmetic.
What is the correct way to read a floating-point number from user input and store it in a variable?
Explanation: Option C is correct because `float(input())` first reads the user input as a string via `input()`, then converts that string to a floating-point number using the `float()` function. This is the standard and only valid way in Python to obtain a float from console input, as `input()` always returns a string.
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?
Explanation: Option C is correct because 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.

Practice all Data Types, Variables, Basic I/O and Operators questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Data Types, Variables, Basic I/O and Operators. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Data Types, Variables, Basic I/O and Operators questions on the PCEP frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Data Types, Variables, Basic I/O and Operators is tested as part of the Certified Entry-Level Python Programmer PCEP blueprint.
