Python Error and Exception Handling
Errors and exceptions can be handled in Python using try...except blocks.
try...except
The try block lets you test a block of code for errors. The except block lets you handle the error.
try:
print(x)
except:
print("An exception occurred")finally
The finally block, if specified, will be executed regardless if the try block raises an error or not.
try:
print(x)
except:
print("Something went wrong")
finally:
print("The 'try except' is finished")Raising an Exception
You can raise an exception using the raise keyword.
x = -1
if x < 0:
raise Exception("Sorry, no numbers below zero")
