Create CaeserCipherDecrypt.py

[dhavalpandey]

Decrypting algorithm that decrypts an encoded string generated by a ceaser cipher. Requires encoded string and key as input.

Summary by Sourcery

New Features:

• Implement a function to decrypt strings encoded with a Caesar cipher, accepting an encoded string and a key as input.

Reviewer's Guide by Sourcery

This PR implements a Caesar cipher decryption algorithm in Python. The implementation handles both uppercase and lowercase letters while preserving non-alphabetic characters. The program takes user input for the encoded string and shift key, then outputs the decoded result.

No diagrams generated as the changes look simple and do not need a visual representation.

Hey @dhavalpandey - I've reviewed your changes - here's some feedback:

Overall Comments:

• Consider separating the cipher logic from I/O operations by moving the input/output code to a separate main() function. This would improve reusability and testability.
• Add error handling for the key input to handle non-integer inputs gracefully. Currently the program will crash if non-numeric input is provided.
• Replace magic numbers (65, 97) with named constants (ord('A'), ord('a')) to improve code readability and maintainability.

Here's what I looked at during the review

• 🟡 General issues: 1 issue found
• 🟢 Security: all looks good
• 🟢 Testing: all looks good

suggestion: Replace magic numbers with more readable constants

Consider using ord('A') instead of 65 and ord('a') instead of 97 to make the code more readable and maintainable.

Suggested change

	result += chr((ord(char) - key - 65) % 26 + 65)
	result += chr((ord(char) - key - ord('A')) % 26 + ord('A'))
