Add/perfect bridge hand #44
Conversation
WalkthroughThe recent updates introduce a new feature for calculating the probability of a perfect bridge hand, add MathJax configuration for rendering equations, and update the documentation structure. Specifically, new Python functions for probability calculations were added, MathJax settings were configured, and the navigation in Changes

The function calc_prob() correctly implements the probability calculation for a perfect bridge hand using combinatorial mathematics. However, consider the following improvements:
- Documentation: Add a docstring to explain the function's purpose, parameters, and return type.
- Debugging Output: The
printstatement within the loop (line 9) might be intended for debugging. It's generally a good practice to remove or comment out such statements in production code or control them via a verbosity flag. - Performance: The repeated calculation of factorials can be computationally expensive. Consider precomputing factorials or using a more efficient approach if performance is a concern.
def calc_prob():
"""

Fraction: The probability of the perfect bridge hand.

prob = 4
for i in range(13):
numerator = (13 - i) * Fraction(
factorial(39 - 3 * i), factorial(3) * factorial(36 - 3 * i)

denominator = Fraction(
factorial(52 - 4 * i), factorial(4) * factorial(48 - 4 * i)
)
prob *= Fraction(numerator, denominator)
return prob

42-44: Main execution block is correctly implemented.The
if __name__ == "__main__":block is standard for Python scripts intended to be executed as the main program. It correctly handles the function call and output.
