前言 Python 是一种非常强大和广泛使用的语言,具有功能齐全的标准库。人们说它是“电池已包含”,这意味着您将需要做的大部分工作都可以在标准库中找到。 这样庞大的功能集可能会让开发人员感到迷失,而且并不总是清楚哪些可用工具最适合解决特定任务。对于这些任务中的许多,也将提供外部库,您可以安装以解决相同的问题。

Using the context manager, the sys.stdout output can be redirected to any other stream or, in conjunction with io.StringIO, to a string. The latter can be especially useful, for example, to capture output from a function that was written to implement a command line interface. It is ...
