Python Error Handling and File Operations: Don't Let The Things Go Wrong

Error Handling 101: Keeping Your Code Crash-Free

Python’s error handling uses try, except, and friends to prevent your program from exploding. Here’s the setup:

try:
    result = 10 / 0
except ZeroDivisionError:
    print("Oops! You can't divide by zero.")

The try block runs the risky code, and if an error (like dividing by zero) occurs, except steps in to handle it.

File Operations: Reading and Writing Like a Pro

Python makes it easy to open, read, and write files. Just remember to close them when you’re done (or better yet, use with to handle that for you).

with open("example.txt", "w") as file:
    file.write("Hello, file!")

Alternative Approach: The finally Block

Use finally if you need something to happen no matter what—like closing a file or ending a connection.

try:
    file = open("example.txt", "r")
    # Read from file
finally:
    file.close()  # Always closes, error or not

Final Words: Catch Those Errors Before They Catch You

With error handling and file operations under your belt, your code’s more reliable—and ready for the real world.
🥂 Cheers to code that works, no matter what!
