Hello all,
Please Dom Grigonis add choices :
- "No preference" choice to first question
- "I don't know" or "I can't tell" to third question
And I will answer to your poll and probably other people will feel and
do the same.
I agree that question 2 makes me prefer C syntax.
But C is not the nicest syntax in my point of view.
In MySQL SQL, there is IF(condition, if_result, else_result)
which I find nice.
Moreover, it fits well with black style of formatting:
foo_var = IF(
this_is_a very_long_condition_expression_which_may_have_nested_parts,
this_is_a very_long_if_result_expression_which_may_have_nested_parts,
this_is_a very_long_else_result_expression_which_may_have_nested_parts,
)
to compare with :
foo_var = (
this_is_a very_long_condition_expression_which_may_have_nested_parts,
? this_is_a very_long_if_result_expression_which_may_have_nested_parts,
: this_is_a very_long_else_result_expression_which_may_have_nested_parts,
)
I can enjoy both, but I prefer the SQL apart from the fact that "IF"
keyword would be ambiguous.
I also enjoy very much :
foo_var = CASE
WHEN condition THEN if_result
WHEN condition2 THEN elif_result
ELSE else_result
END
from SQL.
And CASE is not a reserved keyword and WHEN, THEN, ELSE could have
specific meaning inside of case.
Truly, I would enjoy the following syntax for Python à la black :
foo_var = case(
when condition then if_result
when condition2 then elif_result
else else_result
)
or even more concise and still readable :
foo_var = case(
condition : if_result,
condition2 : elif_result,
else_result,
)
Best regards,
Laurent Lyaudet
