I have a process (class) that I split into several steps (methods). each step can only be invoked if the previous one was successful. I created a method run() that runs the process by checking each step before invoking the next one:
def run(self):
status = False
if step_1():
if step_2():
if step_3():
etc... [several nested IFs]
status = True
else:
self.logger.error('Error in step 3')
else:
self.logger.error('Error in step 2')
else:
self.logger.error('Error in step 1')
return status
Is there a more elegant way (a design pattern?) to avoid these nested IF statements?
Thanks a lot,
