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

NEW QUESTION # 45
A program uses slicing on a string "Python". The expression s[1:4] is evaluated. Which substring will be returned?

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

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".

NEW QUESTION # 46
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?

A. Error
B. [4,5,1,2,3]
C. [1,2,3,[4,5]]
D. [1,2,3,4,5]

Answer: C

Explanation:
The append() method adds its argument as a single element. Therefore, the list [4, 5] is added as one nested list, resulting in [1, 2, 3, [4, 5]].

NEW QUESTION # 47
Which of the following statements about Python functions are correct? (Choose two.)

A. Positional arguments must be passed in the order defined, while keyword arguments can be passed in any order using their parameter names.
B. A function cannot call itself or be passed as an argument to itself.
C. passexecutes the function body and returns its result.
D. Functions can only return numeric values or strings.
E. Default parameters must always come before required ones in the parameter list.
F. If a function does not contain a returnstatement, it returns Noneby default.

Answer: A,F

Explanation:
Positional arguments are matched to parameters by their position, so they must follow the defined order, while keyword arguments are matched by name and can be provided in any order. If a function completes without an explicit return statement, Python returns None automatically.

NEW QUESTION # 48
A program uses while False: followed by print statements inside the loop. The developer expects output. What will actually happen during execution?

A. Error
B. No execution
C. Prints once
D. Infinite loop

Answer: B

Explanation:
The condition False is evaluated before entering the loop. Since it is always false, the loop body is never executed, and no output is produced.

NEW QUESTION # 49
You are analyzing survey results from students about their favorite colors. The list colorsstores individual responses:

You want to:
- find the number of unique colors mentioned using NumPy, and
- determine how often each color was chosen using Counter.
Which code snippet correctly performs both tasks? Select the best answer.
from numpy import unique

A. from collections import Counter
unique_colors = len(unique(colors))
color_counts = Counter(colors)
import numpy as np
B. from collections import Counter
unique_colors = Counter(colors)
color_counts = sum(np.unique(colors))
import numpy as np
C. from collections import Counter
unique_colors = np.unique(colors)
color_counts = Counter(set(colors))
import numpy as np
D. from collections import Counter
unique_colors = len(set(colors))
color_counts = np.unique(colors)

Answer: A

Explanation:
numpy.unique returns the distinct values in the list, and taking its length gives the number of unique colors. Counter(colors) correctly counts how many times each color appears in the responses.
