[英]pylint argues about ternary operator with assignment expression
I have some code like this:我有一些这样的代码:
return (
(1 / a)
if (a := foo())
else 0
)
My pylint argues about this because "Using variable 'a' before assignment", even the evaluation order should be a := foo()
first and then 1 / a
or 0
.我的 pylint 对此争论不休,因为“在赋值之前使用变量 'a'”,甚至评估顺序也应该是
a := foo()
,然后是1 / a
或0
。 I tried pip install --upgrade pylint
, but it seems that pylint still do not agree this.我试过
pip install --upgrade pylint
,但似乎 pylint 仍然不同意这一点。
OK, I find that this is an issue of Pylint: OK,我发现这是Pylint的问题:

"pylint can parse the walrus operator but we haven't actually implemented support for it." “pylint 可以解析 walrus 运算符,但我们实际上还没有实现对它的支持。” (21 Jan)

Anyway, I will modify the code to some equivalent versions which do not cause "Using variable before assignment", for example:无论如何,我会将代码修改为一些不会导致“在赋值前使用变量”的等效版本,例如:
if (a := foo()):
return 1 / a
else:
return 0
