Task 1: The Safe Calculator

This task focuses on creating a function with default parameters and handling a potential error using try...except.

1. Define a function named safe_divide.
2. This function should accept two parameters: numerator and denominator.
3. Give the denominator a default parameter value of 1.
4. Inside the function, use a try...except block.
5. In the try block, calculate the result of numerator / denominator and return it.
6. In the except block, catch the ZeroDivisionError (the error Python gives when you divide by 0).

Resets

1. git reset --soft

   • Effect on Commit History: Moves the HEAD (the current branch) to the specified commit without changing the working directory or the staging area.
   • Staging Area: All changes between the current commit and the target commit remain staged.
   • Working Directory: Files in your working directory remain unchanged.
   • Use Case: Use this when you want to undo a commit but keep the changes staged for a new commit.
