Resolved Issue #43
#Positional vs. Optional Arguments:

##Original Code: The original code did not contain any positional arguments that were explicitly defined. All arguments were optional, but there was no confusion regarding their types.
##Modified Code: The modified code maintains the use of only optional arguments (with - or -- prefixes). This ensures clarity and avoids any potential confusion or errors related to the required parameter.

##Error Handling:
The modified code does not introduce any changes to error handling logic; it retains the same checks for negative values for days_before and days_after. However, it ensures that no invalid usage of required is present.

##Help Messages:
While both versions have help messages for each argument, the modified version slightly refines these messages for clarity and consistency.

##Code Structure:
The overall structure of the code remains unchanged in terms of functionality. The logic for creating directories, initializing the Git repository, generating commits, and pushing to a remote repository is preserved.

##Commenting:
In the modified version, comments were added to clarify what changes were made, particularly regarding the handling of command-line arguments.
