Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions (Q46-Q51):

NEW QUESTION # 46
Given the following string:
text = "Report2024Final"
Which of the following statements are entirely correct? (Choose two.)

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

Answer: A,D,E

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 # 47
A student writes a program using input() to collect user data, then tries to add 5 to the input value without conversion. The program crashes. What is the most likely cause of this behavior?

A. Syntax error
B. input returns string
C. input returns float
D. input returns int

Answer: B

Explanation:
The input() function always returns a string. Attempting to add an integer to a string causes a TypeError. The input must be explicitly converted using int() or float() before performing arithmetic operations.

NEW QUESTION # 48
Which of the following code snippets will output Truefor both printfunctions by correctly identifying the type of each variable and performing valid operations?

Answer: C

Explanation:
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.

NEW QUESTION # 49
A script defines a variable x = None and checks its truth value using a conditional statement. The developer wants to understand how Python evaluates None in Boolean contexts. What will bool(x) return?

A. False
B. True
C. Error
D. None

Answer: A

Explanation:
The value None represents the absence of a value and is treated as False in Boolean expressions. Therefore, calling bool(None) returns False, similar to empty containers or zero values.

NEW QUESTION # 50
How do the analysis and visualization stages of the data lifecycle typically work together?

A. Analysis retrieves raw inputs from dashboards, while visualization uses that input to clean the data.
B. Analysis identifies patterns and insights in processed data, which are then communicated through visualizations for informed decision-making.
C. Analysis produces charts and graphs, while visualization interprets the data to detect outliers.
D. Analysis summarizes archived data, and visualization transforms it into structured tables for storage.

Answer: B

Explanation:
Analysis involves examining processed data to uncover patterns, trends, and insights, and visualization presents those findings in graphical form so stakeholders can clearly understand and act on the results.
