Yes, you can do this:
<condition> and myList.append('myString')
If <condition>
is false, then short-circuiting will kick in and the right-hand side won’t be evaluated. If <condition>
is true, then the right-hand side will be evaluated and the element will be appended.
I’ll just point out that doing the above is quite non-pythonic, and it would probably be best to write this, regardless:
if <condition>: myList.append('myString')
Demonstration:
>>> myList = []
>>> False and myList.append('myString')
False
>>> myList
[]
>>> True and myList.append('myString')
>>> myList
['myString']
