Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions (Q36-Q41):

NEW QUESTION # 36
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?

A. Error
B. 0
C. "555"
D. 1

Answer: C

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 # 37
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?

A. 4, 2, 0
B. 5, 3
C. 5, 4, 3, 2, 1
D. 5, 3, 1

Answer: D

Explanation:
The range starts at 5 and decreases by 2 each step until it reaches a value greater than 0. The generated sequence is 5, 3, and 1.

NEW QUESTION # 38
Given the following string:
text = "Report2024Final"
Which of the following statements are entirely correct? (Choose two.)

A. text[0:6].isalpha() returns True, and text.find("2024") returns 6
B. text[6:8].isdigit()returns True, and text.endswith("Final")returns True
C. text.capitalize()changes Finalto lowercase, and text.find ("L")returns True
D. text.isalpha()returns True, and text.find ("2024")returns True
E. text.capitalize()changes Report2024Finalto REPORT2024FINAL, and text.find("2024")returns 6
F. text[-6].isdigit() returns True, text.startswith("r") returns True

Answer: A,B,C

Explanation:
The slice text[6:8] is "20", which contains only digits, and the string ends with "Final". The first six characters are "Report", which are all alphabetic, and "2024" begins at index 6.

NEW QUESTION # 39
You are reading a data.csvfile line by line. To prepare each line for formatting with f-strings, you need to remove extra whitespace and split the values by commas.
Which line should you insert to correctly clean and parse the input?

A. fields = line.split(', ').trim()
B. fields = line.split().strip(', ')
C. fields = line.strip().split(', ')
D. fields = line.replace(', ', '|').split('|')

Answer: C

NEW QUESTION # 40
What will be the output of the following code?

A. 5 10
B. 5 5
C. 10 5
D. 10 10

Answer: B

Explanation:
The function declares the variable as global and assigns it the value 5. When the function is called, it updates the global variable and returns 5, so both the returned value and the global variable printed afterward are 5.

NEW QUESTION # 41
......
