循环过滤列表
我有代码
for item in list:
if item.some_boolean_property():
several complicated commands here
我想将这些for和压缩if成一个表达式，以便命令可以少缩进一级。我能够将其重构为代码
for item in [item for item in list if item.some_boolean_property()]:
several complicated commands here
它确实有效，但是，你知道，它很丑陋。:) 有没有更聪明的方法来做到这一点？

要保存一个缩进级别，请使用continue跳过您不感兴趣的迭代：
for item in list:
if not item.some_boolean_property():
continue # skip this iteration
# several complicated commands here,
# one indentation level less than above!
- @BelhadjerSamir did you read the question? That is what OP does. They want to save an indent
