python generate函数,python generator转为list,python generator RuntimeError,python generator next,python generator iterator,python generic 类型
Python 是一种高级编程语言，通常用于数据分析、人工智能、Web开发等领域。PythonGenerating help 是 Python 中的一个内置函数，可以用来生成函数或模块的文档字符串。

文档字符串是一个特殊的注释块，可以包含有关函数或模块的信息，例如功能描述、参数说明、返回值类型等。Python 的文档字符串通常遵循一定的格式规范，例如使用 reStructuredText 或 Markdown 来书写。

PythonGenerating help 函数的语法如下：


help([object])


其中，object 参数是可选的。如果指定了 object 参数，则会打印该对象的文档字符串；如果未指定，则会进入交互式帮助界面。

以下是几个使用 PythonGenerating help 函数的例子：

1. 查看内置函数的文档


>>> help(print)
Help on built-in function print in module builtins:

print(...)
print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=False)

Prints the values to a stream, or to sys.stdout by default.
Optional keyword arguments:
file: a file-like object (stream); defaults to the current sys.stdout.
sep: string inserted between values, default a space.
end: string appended after the last value, default a newline.
flush: whether to forcibly flush the stream.
