Mailman 3 Ternary operators in list comprehensions - Python-ideas

5 Oct 2017

a = [1,2,3]
[ x for x  in a if x & 1]
[1, 3]
[ x for x  in a if x & 1 else 'even']
  File "<stdin>", line 1
    [ x for x  in a if x & 1 else 'even']
                                ^
SyntaxError: invalid syntax
I expected [1, 'even', 3]

I would expect that the if expression would be able to provide alternative values through else.

The work around blows it out to:
l = []
for x in a:
  if x&1:  
    l.append(x)
  else:
    l.append('even')

Unless there is a better way?
