Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions:
1. How do the analysis and visualization stages of the data lifecycle typically work together?
A) Analysis produces charts and graphs, while visualization interprets the data to detect outliers.
B) Analysis identifies patterns and insights in processed data, which are then communicated through visualizations for informed decision-making.
C) Analysis summarizes archived data, and visualization transforms it into structured tables for storage.
D) Analysis retrieves raw inputs from dashboards, while visualization uses that input to clean the data.
2. You are working with city names entered by users. These names may contain inconsistent capitalization and unwanted spaces.
To standardize the data, you want to:
- Remove any leading or trailing whitespace, and
- Capitalize the first letter of each word (e.g., convert "new york" to "New York").
For example:
" New york " → "New York"
"lOS ANGELES" → "Los Angeles"
You are given a variable citythat contains the raw input.
Which line of code correctly updates the value of cleaned_cityto apply the required transformation? Select the best answer.
A) cleaned_city = city.strip().capitalize()
B) cleaned_city = city.upper().replace(" ", "")
C) cleaned_city = city.strip().title()
D) cleaned_city = city.upper().strip()
3. A script attempts to divide two numbers using / and //. The values are 7 and 2. The developer wants to understand the difference between true division and floor division. What are the results respectively?
A) 4 and 3
B) 3.5 and 3
C) 3 and 3.5
D) 3 and 4
4. 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('|')
