                          Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions (Q30-Q35):

                          NEW QUESTION # 30
                          A programmer writes a script to test operator precedence using the expression 3 + 4 * 2 ** 2. The goal is to evaluate the result correctly based on Python's operator hierarchy rules. What result should the script produce?

                          Answer: B

                          Explanation:
                          Exponentiation is evaluated first, so 2 ** 2 equals 4. Then multiplication 4 * 4 equals 16. Finally, addition is performed: 3 + 16 results in 19.


                          NEW QUESTION # 31
                          Consider a Python program that assigns a string value "5" to a variable and then attempts to multiply it by an integer 3. The programmer expects numeric multiplication. What will actually happen when the code is executed?

                          Answer: B

                          Explanation:
                          In Python, multiplying a string by an integer repeats the string. Therefore, "5" * 3 produces "555", not a numeric result. This behavior differs from arithmetic multiplication and often confuses beginners.


                          NEW QUESTION # 32
                          A script attempts to divide two numbers using / and //. The values are 7 and 2. The developer wants to understand the difference between true division and floor division. What are the results respectively?

                          Answer: B

                          Explanation:
                          The / operator performs true division, returning a float result of 3.5. The // operator performs floor division, truncating the decimal part and returning the integer value 3.


                          NEW QUESTION # 33
                          A Python script includes the expression not False and True. The developer is unsure how logical operators are evaluated in terms of precedence. What will be the final Boolean result of this expression?

                          Answer: C

                          Explanation:
                          The not operator has higher precedence than and, so not False becomes True first. Then True and True is evaluated, resulting in True as the final Boolean value.


                          NEW QUESTION # 34
                          Which task is traditionally or typically performed by a data analyst, and not by a data scientist or analytics specialist? Select the best answer.

                          Answer: C

                          Explanation:
                          Creating summary tables and charts to describe patterns in historical data is a core responsibility of a data analyst, focusing on descriptive analytics and reporting rather than building predictive models, machine learning systems, or engineering data pipelines.


                          NEW QUESTION # 35
                          ......
