What is the difference between try-except and if-else in Python?

In Python, try-except is used for handling exceptions, while if-else is for conditional logic. Try-except catches errors that occur during execution, allowing the program to continue running. If-else checks conditions and executes code based on whether the condition is true or false.

Can you give me an example of each?

Sure! For try-except:

try:
    result = 10 / 0
except ZeroDivisionError:
    print('You cannot divide by zero!')

For if-else:

number = 10
if number > 0:
    print('Positive number')
else:
    print('Non-positive number')

When should I use try-except instead of if-else?

Use try-except when you expect that an error might occur during execution, such as file operations or network requests. If-else is better for predictable conditions where you can check the state before executing code.

Are there any performance differences between them?

Yes, try-except can be slower if exceptions are raised frequently, as handling exceptions has overhead. If-else is generally faster for predictable conditions since it avoids the overhead of exception handling.
