Python Ternary Operator Without else

Question

Is it possible to do this on one line in Python?

if :
    myList.append(\'myString\')

I have tried the ternary operator:

Answer 1

Yes, you can do this:

 and myList.append('myString')

If is false, then short-circuiting will kick in and the right-hand side won't be evaluated. If 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 : myList.append('myString')

Demonstration:

>>> myList = []
>>> False and myList.append('myString')
False
>>> myList
[]
>>> True and myList.append('myString')
>>> myList
['myString']
