此外,还可以将table 和array of tables作为集合来组织多个键值对。您将在本节的其余部分了解有关所有这些内容的更多信息,以及如何在 TOML 中指定它们。 注:TOML 支持与 Python 语法相同的注释(#)。 如前所述,键值对是 TOML 文档中的基本构建块。您可以使用<key> = <value>语法: 代码语言:javascript 代码运行...

String Concatenation:When working with strings, frequently combine them with other strings or data types. Converting an integer to a string allows you to concatenate it with other strings without incurring type-related errors. For example, while creating dynamic messages or generating file locations. ...

You can combine packing and unpacking in one statement to run a parallel assignment: Python >>> s1, s2, s3, s4 = "foo", "bar", "baz", "qux" >>> s1 'foo' >>> s2 'bar' >>> s3 'baz' >>> s4 'qux' Again, the number of elements in the tuple on the left of the ass...
