Error handling in programming is how you manage errors or unexpected situations that occur while your program is running. In Python, this is done using exceptions. Here’s a simple explanation of error handling in Python:
Exceptions are special objects that represent errors or unexpected events in a program. When an error occurs, an exception is "raised" (or thrown). If the program doesn't handle the exception, it will stop and show an error message.
You handle errors in Python using try, except, else, and finally blocks.
The try block lets you test a block of code for errors. The except block lets you handle the error.
try:
# Code that might cause an error
x = 10 / 0
except ZeroDivisionError:
# Code to run if there's a ZeroDivisionError
print("You can't divide by zero!")
In this example:
The else block lets you run code if no errors were raised in the try block.
try:
x = 10 / 2
except ZeroDivisionError:
print("You can't divide by zero!")
else:
print("The division was successful.")
In this example:
The finally block lets you run code regardless of the result of the try and except blocks. This is useful for cleaning up resources, such as closing files or releasing network connections.
try:
x = 10 / 2
except ZeroDivisionError:
print("You can't divide by zero!")
else:
print("The division was successful.")
finally:
print("This will run no matter what.")
In this example:
You can create your own exceptions by defining a new class that inherits from the built-in Exception class.
class MyCustomError(Exception):
pass
try:
raise MyCustomError("Something went wrong!")
except MyCustomError as e:
print(e)
In this example:
