Hi,
AFAIK, we do not have "postfix conditionals" in Python, i.e. a condition
appended to a
statement, which determines whether the statement runs or not:
py> for i in [False]:
... break if not i
The above piece of code is equivalent to this in Python:
py> for i in [False]:
... if not i
... break
I believe that the first example is superior to the second example when
the two is compared
for readability and intuitiveness. We already have a ternary statement
'conditional expression', which happens to be a ternary as opposed to
binary expression.
that looks similar,
py> print('hi') if True else None
so I reckon there would be no breakage in old code if this kind of
syntax was added. Ruby has
this, and AFAIK Perl also does.
I lack the knowledge of whether the community has opinions on this kind
of notation,
In general, negative on pure duplication. Guido has said he strongly
dislikes the perl reverse if.
