It would be helpful if the rules of the game were spelled out more clearly.
The conditional expression is defined as X if C else Y.
We don't know the precedence of the "if" operator. From the little test
below, it seem to have a lower precedence than "or".
Thus, it is desirable for the user to put the conditional expression in
parentheses.

# PEP 308 defines a conditional expression as X if C else Y
# but we don't know exactly what X is supposed to be.
# It doesn't seem to be spelled out in the syntax.
def main():
names= ['abc', 'def', '_ghi', 'jkl', '_mno', 'pqrs']
res= ''
for w in names:
res= res + w if w[0] != '_' else ''
z= 1
print 'res1:', res
res= ''
for w in names:
res= res + (w if w[0] != '_' else '')
z= 1
print 'res2:', res
if __name__ == '__main__':
main()
Result:
[Dbg]>>>
res1: pqrs
res2: abcdefjklpqrs
