You need to generate invoice numbers for even-numbered clients, starting at 1000 and going up to (but not including) 1010. What output will this code produce? for client in range(1000, 1010, 2):     print(client) 1000, 1001, 1002, …, 1009B. 1000, 1002, 1004, 1006, 1008C. 1000, 1002, 1004, 1006, 1008, 1010D. 1002, 1004, 1006, 1008 Answer: B Explanation:This range(start, stop, step) includes the start (1000) and goes up to but not including 1010, stepping by 2. A and C include invalid values for the given step and bounds. D starts at 1002, which is incorrect.

You loop through a list of coupon codes. Skip the expired code “DISC0” and stop processing once you hit the “FINAL” flag.How many codes are printed by this loop? python CopyEdit codes = [‘DISC10’, ‘DISC0’, ‘DISC20’, ‘FINAL’, ‘DISC30’] for code in codes:     if code == ‘DISC0’:         continue     if code == ‘FINAL’:         break     print(code) Answer: 2 Explanation: “DISC10” is printed “DISC0” is skipped due to continue “DISC20” is printed “FINAL” triggers the break, stopping before printing “DISC30” is never reached

A coordinator needs to contact every 3rd vendor in a list of 30. If vendors are numbered from 1 to 30, which code correctly selects vendor numbers: 1, 4, 7, …? for vendor in range(1, 31, 3): print(vendor)B. for vendor in range(3, 30): print(vendor)C. for vendor in vendors: if vendor % 3 == 0: print(vendor)D. for vendor in range(0, 30, 3): print(vendor + 1) Answer: A Explanation:Option A begins at 1 and increments by 3, selecting every third vendor. B starts at 3, not 1 C selects vendors divisible by 3, not every third D would work but outputs 1, 4, 7… using an offset; A is clearer and more direct.

A store manager creates a variable: store_code = “WK94HQ” What will store_code[2] return?OPTIONS:A. 9B. WC. KD. 4 ANSWER:A. 9 EXPLANATION:Python uses zero-based indexing, so position 2 refers to the third character. In “WK94HQ”, the characters are: 0: W 1: K 2: 9

A marketing analyst is preparing a report that includes both Python code and written explanations of their findings. They want the report to be interactive and easy to share with team members via Google Drive. Which tool is best suited for this task?OPTIONS:A. Microsoft WordB. Google SheetsC. Jupyter Notebook in Google ColabD. Visual Studio Code ANSWER:C. Jupyter Notebook in Google Colab EXPLANATION:Google Colab is a cloud-based Jupyter Notebook that supports both code and markdown, making it ideal for combining analysis and explanation in a single, shareable document.

An operations analyst wants to calculate daily production totals using this function: python CopyEdit def total_output(daily_counts):     total = 0     for count in daily_counts:         total += count     return total What does the function return when called as total_output([120, 135, 150, 110])? OPTIONS: 515B. 480C. 150D. 135 ANSWER: A EXPLANATION:The function adds all the numbers: 120 + 135 + 150 + 110 = 515. This demonstrates how loops inside functions can aggregate data efficiently.

  Consider this function used by an operations analyst: python CopyEdit def reorder_notice(item, days_left):     if days_left < 3:         return item + " needs to be reordered soon."     else:         return item + " is sufficiently stocked." What is returned by reorder_notice("Printer Ink", 2)? OPTIONS: Printer Ink needs to be reordered soon.B. Printer Ink is sufficiently stocked.C. Reorder needed for Printer Ink.D. 2 needs to be reordered soon. ANSWER: A EXPLANATION:Since days_left is 2 (less than 3), the first return statement is triggered. This demonstrates how functions can use conditional logic to create context-aware responses.

A tech startup estimates that the probability of a server outage during peak hours is 0.08. What is the probability that there is not a server outage during peak hours? ANSWER: 0.92 EXPLANATION:The complement rule states that the probability of an event not occurring is 1 minus the probability of it occurring.1 – 0.08 = 0.92.
