DYD :
I know in a function you can exit the function using return,
def function():
return
but can you exit a parent function from a child function?
Example:
def function()
print("This is the parent function")
def exit_both():
print("This is the child function")
# Somehow exit this function (exit_both) and exit the parent function (function)
exit_both()
print("This shouldn't print")
function()
print("This should still be able to print")
I tried raising an Exception, as this answer suggests, but that just exits the whole program.
dspencer :
You can raise an exception from exit_both, then catch that where you call function in order to prevent the program being exited. I use a custom exception here as I don't know of a suitable built-in exception and catching Exception itself is to be avoided.
class MyException(Exception):
pass
def function():
print("This is the parent function")
def exit_both():
print("This is the child function")
raise MyException()
exit_both()
print("This shouldn't print")
try:
function()
except MyException:
# Exited from child function
pass
print("This should still be able to print")
Output:
This is the parent function
This is the child function
This should still be able to print
