Question

Review the code snippet below:
name1 = "Betty joe"
name2 = "Betty Jean"
name3 = "Betty Jane"
if name1 < name2 :
   if name1 < name3 :
       print(name1, "is first")
   else :
       print(name3, "is first")
else :
   if name2 < name3 :
      print(name2, "is first")
   else :
      print(name3, "is first") 
what output is produced?

We start by restating the given code and the four possible outputs to evaluate each option. The code defines three strings: - name1 = "Betty joe" - name2 = "Betty Jean" - name3 = "Betty Jane" It then performs a pair of nested comparisons to decide which name prints as first: - If name1 < name2, then compare name1 with name3 to decide the winner. - Otherwise, compare name2 with name3 to decide the winner. Now, evaluate each option one by one with the actual Python-style string comparisons in mind (lexicographic, case-sensitive): Option A: "Betty joe is first" - This would correspond to the code printing name1 + " is first" at some branch. - To print name1 in the final result, the condition must lead to name1 being determined as first. - However, comparing name1 and name2: - name1 = "Betty joe" vs name2 = "Betty Jean" share the prefix "Betty "; the next characters are 'j' in name1 and 'J' in name2. - In ASCII, lowercase 'j' comes after uppercase 'J', so 'j' > 'J', meaning name1 < name2 is False. - Since the first comparison is False, we move to the else branch and compare name2 with name3: - name2 = "Betty Jean" vs name3 = "Betty Jane" share "Betty J"; next letters are 'e' in Jean vs 'a' in Jane. - 'e' > 'a', so name2 < name3 is False. - Therefore, the code executes the inner else and prints name3 + " is first" (i.e., "Betty Jane is first"). - Conclusion for this option: printing "Betty joe is first" would be incorrect given the actual lexicographic comparisons described above. Option B: "Betty Jean is first" - This would require name2 to be determined as first. - As shown, name1 < name2 is False due to the case difference on the next character after the shared prefix; the code follows the else branch. - Then evaluating name2 < name3 also yields False because "Betty Jean" > "Betty Jane" lexicographically (the 'e' in Jean comes after the 'a' in Jane at the differing position). - Thus the program does not print name2 as first; it prints name3 as first in the else-branch path. - Therefore, this option is incorrect for the actual code behavior. Option C: "Betty Jane is first" - This matches the outcome we computed step by step: - name1 < name2 is False (due to 'j' > 'J' after the shared prefix), so we go to the else branch. - In the else branch, name2 < name3 is False (since "Betty Jean" is lexicographically greater than "Betty Jane"). - The else of that inner branch executes, printing name3 + " is first" → "Betty Jane is first". - Therefore, this option aligns with the actual code execution. Option D: "Betty joe is firstBetty Jean is firstBetty Jane is first" - This option appears to concatenate multiple phrases without spaces, which would not occur given the code structure. - The code prints exactly one string followed by " is first"; there is no concatenation of multiple name labels in a single print call. - Hence this option does not reflect the program’s actual single-output print statement. Across all options, the accurate step-by-step tracking shows the path that leads to printing "Betty Jane is first"; the other outputs mismatch either due to incorrect comparison results or structural issues in the print statement. The reasoning above follows the exact lexicographic, case-sensitive comparison behavior of Python string comparison and applies it to the given names in their exact forms.
