NO.31 You are developing a temperature control module for a laboratory incubator. Your objectives are to:
– generate timestamps every 10 minutes over a 3-hour span (i.e., 0 to 180 minutes), and
– simulate five evenly spaced target temperatures between 35.0°C and 37.0°C for system calibration.
Which code snippet correctly produces both sequences using NumPy? Select the best answer.
import numpy as np

NO.32 A list is reversed using slicing: lst[::-1]. The programmer wants to confirm whether this modifies the original list or creates a new one. What is the correct behavior?

NO.33 A government agency collects citizen data for various public services.
What is the primary reason for emphasizing careful data management throughout the entire data lifecycle in this context? Select the best answer.

NO.34 A teacher wants to compare the number of students in different school clubs:

Which type of chart would be most appropriate to show this comparison? Select the best answer.

NO.35 Which of the following statements about Python functions are correct? (Choose two.)

NO.36 A Python loop uses range(5, 0, -2) to iterate backward. The programmer expects a decreasing sequence. Which values will actually be generated when this loop runs?

NO.37 A dictionary is defined as d = {“a”:1, “b”:2}. The programmer accesses d[“c”]. What happens when this line executes?

NO.38 What will be the output of the following code?

NO.39 A Python script checks membership using “a” in “apple”. The developer wants to understand how membership works for strings. What result will this expression produce?

NO.40 You are given the following list of daily step counts:
steps = [8230, 9020, 7640, 8760, 10020, 2546, 9817]
Your task is to calculate:
– the standard deviation of the step counts,
– the average rounded up to the nearest whole number, and
– the median of the step counts.
Which code snippet correctly performs all three tasks? Select the best answer.
import statistics

NO.41 The following chart shows how a student spends 24 hours in a day:

Which statements are most accurate? (Choose two.)

NO.42 You have collected sales data and want to compute the average using the NumPy library.
Which option correctly shows how to install NumPy and use it in your code to perform this task?

NO.43 How do the analysis and visualization stages of the data lifecycle typically work together?

NO.44 You are working with city names entered by users. These names may contain inconsistent capitalization and unwanted spaces.
To standardize the data, you want to:
– Remove any leading or trailing whitespace, and
– Capitalize the first letter of each word (e.g., convert “new york” to “New York”).
For example:
” New york ” → “New York”
“lOS ANGELES” → “Los Angeles”
You are given a variable citythat contains the raw input.
Which line of code correctly updates the value of cleaned_cityto apply the required transformation? Select the best answer.

NO.45 A loop is designed using range(1, 6, 2) to iterate through numbers. The developer wants to know exactly which values will be generated during execution. Which sequence correctly represents the values produced?

NO.46 A financial technology company is reviewing its data practices to ensure legal and ethical compliance.
Which of the following actions would support responsible data handling and align with regulations like GDPR, HIPAA, and CCPA? (Choose two.)

NO.47 A list is defined as [1, 2, 3]. The programmer uses the method .append([4, 5]). What will the resulting list look like after execution?

NO.48 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?

NO.49 A loop includes a break statement when a condition is met. The programmer wants to understand how break affects loop execution. What happens when break is executed inside the loop?

NO.50 A program uses while False: followed by print statements inside the loop. The developer expects output. What will actually happen during execution?

NO.51 The following chart shows how a student spends 24 hours in a day:

Which statements are most accurate? (Choose two.)
