Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions (Q45-Q50):

NEW QUESTION # 45
The following chart shows how a student spends 24 hours in a day:

Which statements are most accurate? (Choose two.)

A. Sleep and school take up the majority of time in a day.
B. Leisure accounts for a moderate portion of the student's daily schedule, larger than commuting but smaller than the time spent at school.
C. Commuting is the second most time-consuming activity.
D. School and homework together take up half of the day's time.
E. Leisure and meals combined equal the time spent at school.
F. More time is spent commuting than on leisure.

Answer: A,B

Explanation:
The largest portions of the chart are sleep and school, and together they clearly make up more than half of the day. Leisure appears as a mid-sized segment that is larger than commuting but smaller than school, fitting the description of a moderate portion.

NEW QUESTION # 46
You are given a short Python script that uses both arithmetic and assignment operators. The variable x is initialized as 4, then updated using x *= 2 + 3. What will be printed when the final value of x is displayed?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
Python evaluates the addition first because of operator precedence. The expression 2 + 3 equals
5, then x *= 5 multiplies the current value of x (4) by 5, resulting in a final value of 20.

NEW QUESTION # 47
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().strip(', ')
B. fields = line.split(', ').trim()
C. fields = line.strip().split(', ')
D. fields = line.replace(', ', '|').split('|')

Answer: C

NEW QUESTION # 48
You are writing a function to validate battery voltage readings. The rules are:
- If the reading is "MISSING"or None, return "Missing".
- If the value is below 2.5or above 4.2, return "Outlier".
Otherwise, return "Normal".
Which version correctly implements this logic using the most robust conditional and nested structures? Select the best answer.

Answer: D

Explanation:
It first handles the non-numeric cases ("MISSING" and None) in a single condition, preventing invalid comparisons, and then cleanly checks the numeric outlier bounds using an or condition (<
2.5 or > 4.2) before defaulting to "Normal".

NEW QUESTION # 49
A program uses slicing on a string "Python". The expression s[1:4] is evaluated. Which substring will be returned?

A. ytho
B. yth
C. ythn
D. tho

Answer: B

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