-- In Python, for-loops use the scope they exist in and leave their defined loop-variable behind. This also applies if we explicitly defined the for-loop variable in the global namespace before. In this case, it will rebind the existing variable.
+- 在 Python 中, for 循环使用所在作用域并在结束后保留定义的循环变量. 如果我们曾在全局命名空间中定义过循环变量. 在这种情况下, 它会重新绑定现有变量.
 
-- The differences in the output of Python 2.x and Python 3.x interpreters for list comprehension example can be explained by following change documented in [What’s New In Python 3.0](https://docs.python.org/3/whatsnew/3.0.html) documentation:
+- Python 2.x 和 Python 3.x 解释器在列表推导式示例中的输出差异, 在文档 [What’s New In Python 3.0](https://docs.python.org/3/whatsnew/3.0.html) 中可以找到相关的解释:
 
-    > "List comprehensions no longer support the syntactic form `[... for var in item1, item2, ...]`. Use `[... for var in (item1, item2, ...)]` instead. Also, note that list comprehensions have different semantics: they are closer to syntactic sugar for a generator expression inside a `list()` constructor, and in particular the loop control variables are no longer leaked into the surrounding scope."
+    > "列表推导不再支持句法形式 `[... for var in item1, item2, ...]`. 取而代之的是 `[... for var in (item1, item2, ...)]`. 另外, 注意列表推导具有不同的语义: 它们更接近于 `list()` 构造函数中生成器表达式的语法糖(译: 这一句我也不是很明白), 特别是循环控制变量不再泄漏到周围的作用域中."
