Error Handling in Python (JavaScript to Python Mindset) Every program can face unexpected situations — invalid input, missing files, division by zero, etc. Error handling prevents the program from crashing and allows us to deal with problems gracefully. In JavaScript, we use . In Python, we use . Basic Error Handling JavaScript: Python: Python raises specific exceptions ( , , , etc.). The block catches and handles them. Catching Multiple Exceptions JavaScript: Python: You can have multiple blocks for different errors. Unlike JS (where division by zero is ), Python raises an error. Catch-All Exception Sometimes you don’t know what error might occur. Python: This is like JavaScript: The Block Both Python and JavaScript support a block that always runs. Python: JavaScript: Else with Try-Except (Python Only) Python has an block that runs if no exception occurs: JavaScript has no direct equivalent — you just put logic inside . Example: Safe Calculator Quick Takeaway Python uses instead of . Catch specific errors ( , , etc.) or use a general . Use for cleanup code (like closing files, releasing resources). Python also has with , which runs if no errors occur. Handle errors gracefully instead of letting your program crash.
