최신 Python Institute PCED PCED-30-02 무료샘플문제 (Q40-Q45):

질문 # 40
A program compares two values using == and is. The variables a = 256 and b = 256 are defined.
What is the expected result of a is b in most Python implementations?

정답：A

설명：
Python caches small integers for efficiency. Since 256 is typically within the cached range, both variables reference the same object in memory, making a is b evaluate to True.


질문 # 41
Which of the following code snippets will output Truefor both printfunctions by correctly identifying the type of each variable and performing valid operations?

정답：A

설명：
Adding an integer and a float produces a float result, so checking that the type of the sum is float evaluates to True. The variable holding 3.0 is a float, so the isinstance check for float also evaluates to True.


질문 # 42
A program uses slicing on a string "Python". The expression s[1:4] is evaluated. Which substring will be returned?

정답：A

설명：
Slicing includes the start index but excludes the end index. Characters at indices 1, 2, and 3 are selected, producing the substring "yth".


질문 # 43
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

정답：B

설명：
np.arange(0, 181, 10) generates timestamps from 0 through 180 in 10-minute steps (end is excluded, so using 181 includes 180). np.linspace(35.0, 37.0, 5) generates five evenly spaced temperatures including both 35.0°C and 37.0°C.


질문 # 44
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?

정답：A

설명：
The in operator checks for substring presence. Since the character "a" exists in "apple", the expression evaluates to True, demonstrating how membership works for strings in Python.
