calculator.py crashes on division by zero

[JAHNAVI-YERRAMSETTI]

###📌 Problem
When using the calculator script, the program crashes if the user tries to divide by zero.

💥 Steps to Reproduce

1. Run calculator.py
2. Choose the division operation
3. Enter any number (e.g., 10) and then 0

❗Actual Behavior

Program crashes with a ZeroDivisionError.

✅ Expected Behavior

The script should catch this error and show a user-friendly message like:
"Error: You cannot divide by zero."

🛠️ Suggested Fix

Wrap the division operation in a try-except block to catch ZeroDivisionError.

try:
    result = a / b
except ZeroDivisionError:
    print("Error: Cannot divide by zero.")
