Fix file handling and configuration parsing bugs #52
Conversation
WalkthroughAdds multiple new Python modules implementing basic algorithms, math utilities, string/validation helpers, and a performance timing demo, each with top-level print demonstrations. Also includes a Windows bash.exe.stackdump artifact. No edits to existing files; all additions are new files and functions. Changes

Caution
Some comments are outside the diff and can’t be posted inline due to platform limitations.
⚠️ Outside diff range comments (1)
bash.exe.stackdump (1)
1-29: Remove crash dump and update ignore rules
Deletebash.exe.stackdump(and any other dump artifacts) from the PR and add the following to.gitignore:# .gitignore (add) # Windows crash/core dumps *.stackdump *.dmp *.mdmp bash.exe.stackdumpThis binary leak is unrelated to the config-parsing work—consider moving the new algorithm modules into a separate PR.
🧹 Nitpick comments (35)
buggy_cube.py (2)
1-2: Docstring and clean up fix-note commentThe inline “Bug fixed” note is noise in production code; prefer a concise docstring.
-def cube(n): - return n * n * n # Bug fixed: now calculates cube +def cube(n): + """Return n cubed.""" + return n * n * n
1-4: PR scope mismatch with objectivesThese algorithm utilities don’t match the PR title/description about config parsing/file handling. Please confirm scope or split into a separate PR to keep reviews focused. I can help move the unrelated files if needed.
buggy_anagram.py (1)
1-2: Normalize input for robust anagram checksCurrent approach is case-insensitive but treats spaces/punctuation as significant. Normalize by using
casefold()and filtering to alphanumerics.-def is_anagram(s1, s2): - return sorted(s1.lower()) == sorted(s2.lower()) # Bug fixed: handle case sensitivity +def is_anagram(s1, s2): + """Case-insensitive, punctuation/space-agnostic anagram check.""" + a = sorted(ch for ch in s1.casefold() if ch.isalnum()) + b = sorted(ch for ch in s2.casefold() if ch.isalnum()) + return a == bbuggy_product_list.py (2)
1-5: Prefermath.prodand clarify empty-input semantics.Leaner, faster, and clearer. Also document that empty lists return 1 (neutral element) and add type hints.
+from math import prod -def product_list(lst): - result = 1 # Bug fixed: start with 1 - for num in lst: - result *= num - return result +def product_list(lst): + """Return the product of numbers in lst. For an empty list, returns 1.""" + return prod(lst)If your runtime is < Python 3.8 (no
math.prod), say so and I’ll propose a compatible fallback.
1-7: PR scope mismatch: confirm intent.PR description mentions config parsing/file handling, but this file adds math utilities. Please confirm scope or update the PR description/title.
buggy_gcd.py (1)
1-4: Normalize to non-negative result and add minimal typing.Current code can return negative gcd for negative inputs. Normalize inputs to match
math.gcdbehavior.-def gcd(a, b): - while b: - a, b = b, a % b # Bug fixed: use modulo, not addition - return a +def gcd(a: int, b: int) -> int: + a, b = abs(a), abs(b) + while b: + a, b = b, a % b + return abuggy_min_in_list.py (1)

2-6: Don't lowercase the rest; keep spacing stable and validate input.
.capitalize()forces the rest of the word to lowercase (e.g., "iPhone" → "Iphone"). Also add a type check.Apply:
-def capitalize_words(sentence): - words = sentence.split(' ') - # Bug fixed: modify the words list in-place - for i in range(len(words)): - words[i] = words[i].capitalize() - return ' '.join(words) +def capitalize_words(sentence: str) -> str: + if not isinstance(sentence, str): + raise TypeError("sentence must be a str") + words = sentence.split(' ') + for i in range(len(words)): + if words[i]: + words[i] = words[i][0].upper() + words[i][1:] + return ' '.join(words)

5-10: Tie-break choice: prefer list1 on equals for determinism.Using <= keeps items from list1 before list2 when equal, which can be desirable.
- if list1[i] < list2[j]: + if list1[i] <= list2[j]: result.append(list1[i]) i += 1 else: result.append(list2[j]) j += 1buggy_nth_largest.py (2)
1-7: Dedup + sort works; reduce duplication by delegating to n-th.-def find_second_largest(numbers): - # Bug fixed: handle duplicate values by using set to get unique numbers - unique_numbers = list(set(numbers)) - if len(unique_numbers) < 2: - return None # Not enough unique numbers - unique_numbers.sort(reverse=True) - return unique_numbers[1] +def find_second_largest(numbers): + # Delegate to n-th largest for a single source of truth + return find_nth_largest(numbers, 2)
9-14: For large inputs and small n, use heapq.nlargest for O(n log n) with small constant.-def find_nth_largest(numbers, n): - # Bug fixed: handle case when n > length of unique numbers - unique_numbers = sorted(set(numbers), reverse=True) - if n > len(unique_numbers) or n <= 0: - return None # Invalid n value - return unique_numbers[n-1] +def find_nth_largest(numbers, n): + # Handle invalid n + if n <= 0: + return None + # Deduplicate then select n largest efficiently + uniques = set(numbers) + if n > len(uniques): + return None + from heapq import nlargest + return nlargest(n, uniques)[-1]buggy_validation.py (3)
3-6: Prefer re.fullmatch for entire-string validation.Anchors plus match work, but fullmatch is clearer and avoids surprises.
def validate_email(email): # Bug fixed: proper email validation with regex pattern = r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$' - return re.match(pattern, email) is not None + return re.fullmatch(pattern, email) is not None
8-12: Accept common phone formats by stripping non-digits before validating.def validate_phone(phone): # Bug fixed: check that all characters are digits - if len(phone) == 10 and phone.isdigit(): - return True - return False + digits = "".join(filter(str.isdigit, phone)) + return len(digits) == 10
14-21: Password rules OK; clarify policy or extend checks if needed.If lowercase is required or a broader special set is desired, update accordingly and document.
buggy_performance.py (5)
6-17: Replace manual global cache with @lru_cache and validate integer inputRemoves global state, tightens input validation, and keeps the API simple.

6-17: Optional: Provide an iterative variant to avoid recursion limits for very large nFor very large inputs, recursion can hit RecursionError even with caching. Consider adding this helper and timing that instead.

In buggy_average_of_squares.py around lines 1 to 2, the function divides by
len(lst) which raises ZeroDivisionError for an empty list; add an explicit guard
at the top to handle empty input — either raise a clear ValueError like
"average_of_squares() requires a non-empty list" or return a defined value (e.g.
0 or None) depending on intended API; implement the chosen behavior and update
the function to check for empty list before computing the sum to avoid division
by zero.

In buggy_fibonacci.py around lines 1 to 4 the fibonacci function accepts
negative inputs and uses naive exponential recursion; validate that n is a
non-negative integer (raise ValueError for negatives or non-integers) and
implement memoization (e.g., use an internal cache dict or functools.lru_cache)
to store computed results and return cached values to avoid redundant recursive
calls; keep base cases for 0 and 1, and ensure the function signature and
behavior remain consistent after adding input validation and caching.

In buggy_sum_of_cubes.py around line 4, the module executes a demo print at
import time (print(sum_of_cubes([1, 2, 3]))), which causes side effects when the
module is imported; fix it by removing the top-level print or moving it under an
if __name__ == "__main__": guard so the demo runs only when the file is executed
as a script.

Avoid top-level prints; guard with main.
Prevents side effects on import and keeps modules library-friendly.

In buggy_temperature.py around lines 11 to 12 the module performs top-level
prints which cause side effects on import; wrap those print calls inside a
guard: add an if __name__ == "__main__": block and place the two print
statements inside it (properly indented) so they only execute when the script is
run directly, not when imported.

Demo text is misleading and prints at import; fix messaging and guard.

In buggy_validation.py around lines 23 to 26, the demo prints run on import and
the messages are misleading; move these test print statements into a main guard
(if __name__ == "__main__":) so they only execute when run as a script, and
update the printed messages to clearly indicate these are expected-invalid test
cases (e.g., "expected invalid: ...") so the output isn't misleading.
Enhanced config file handling with comprehensive error handling, file existence checks, malformed line handling, type conversion for booleans/numbers, and proper escaping of special characters in values.
