Using try vs if in python
- by artdanil
Is there a rationale to decide which one of try or if constructs to use, when testing variable to have a value?
For example, there is a function that returns either a list or doesn't return a value. I want to check result before processing it. Which of the following would be more preferable and why?
result = function();
if (result):
for r in result:
#process items
or
result = function();
try:
for r in result:
#process items
except TypeError:
pass;
