The try block lets you test a block of code for errors.
The except block lets you handle the error.
The finally block lets you execute code, regardless of the result of the try- and except blocks.
You can define as many exception blocks as you want, e.g. if you want to execute a special block of code for a special kind of error:
ExamplePrint one message if the try block raises a NameError and another for other errors:
try:
print(x)
except NameError:
print("Variable x is not defined")
except:
print("Something else went wrong")
