Add Python utility file (simple_utils.py)

[karandlakhwani-arch]

Created a new directory (python) and added simple_utils.py containing basic utility functions:

• reverse_string(): reverses a string
• count_words(): counts number of words in a sentence
• celsius_to_fahrenheit(): converts Celsius to Fahrenheit

This PR is part of the CodeRabbit onboarding exercise.

Summary by CodeRabbit

• New Features
  • Introduced basic text utilities: quickly reverse input and get word counts based on whitespace separation.
  • Added a temperature converter from Celsius to Fahrenheit using the standard formula.
  • These tools run instantly with no setup, streamlining simple text manipulation and unit conversion tasks in supported areas of the product and improving consistency where such transformations are needed.

Walkthrough

Introduces a new Python module python/simple_utils.py with three standalone utility functions: reverse_string(text), count_words(sentence), and celsius_to_fahrenheit(celsius). Each function performs a single, straightforward operation without additional error handling or state.

Changes

Cohort / File(s)	Summary
Utility Module Addition python/simple_utils.py	New module defining three functions: reverse_string(text) to reverse strings, count_words(sentence) to split on whitespace and count tokens, and celsius_to_fahrenheit(celsius) implementing (celsius * 9/5) + 32.

Poem

I twitch my ears at tidy tools anew,
Three little helpers, crisp as morning dew—
Flip a string, count words that grew,
Warm a chill to Fahrenheit hue.
Thump-thump, I approve this queue! 🐇✨

3-5: LGTM! Consider adding type hints.

The string reversal implementation is correct and uses idiomatic Python slicing.

Optionally, you can add type hints to improve code clarity:

-def reverse_string(text):
+def reverse_string(text: str) -> str:
     """Reverses the characters in a string."""
     return text[::-1]

---

7-9: LGTM! Consider adding type hints.

The word counting logic is correct. Using split() without arguments properly handles multiple consecutive spaces and various whitespace characters.

Optionally, you can add type hints:

-def count_words(sentence):
+def count_words(sentence: str) -> int:
     """Counts the number of words in a sentence."""
     return len(sentence.split())

---

11-13: LGTM! Consider adding type hints.

The temperature conversion formula is correct and uses proper float division.

Optionally, you can add type hints to accept both int and float:

-def celsius_to_fahrenheit(celsius):
+def celsius_to_fahrenheit(celsius: float) -> float:
     """Converts Celsius temperature to Fahrenheit."""
     return (celsius * 9/5) + 32
