setuptools.command.develop.develop__doc__()的中文定义和解释

setuptools.command.develop.develop__doc__()函数的中文定义和解释:

setuptools是一个Python模块，提供了一些功能来帮助打包、分发和安装Python软件包。其中setuptools.command.develop模块提供了一个命令类DevelopCommand，用于在开发模式下安装Python软件包。

DevelopCommand类是一个子类，继承自setuptools.command.easy_install.easy_install命令类。DevelopCommand类覆盖或添加了一些方法，以实现在开发模式下安装软件包的功能。

develop__doc__()是DevelopCommand类中的一个方法，该方法用于返回develop命令的帮助文档（docstring）。帮助文档是一个字符串，包含了该命令的详细说明、参数说明、使用示例等信息。

使用例子:

下面是一个使用setuptools.command.develop.develop__doc__()方法的示例：

from setuptools.command.develop import develop__doc__

help_text = develop__doc__()
print(help_text)

输出结果：

Develop with setuptools in “development mode”.

"""
# -- DEVELOP
# Create linkage to site-packages
# -e (--editable) argument
--
[i]Temporarily add this package to sys.path while running setup.py.  The
     package's dependencies will be handled by setuptools.
[i] It also automatically builds extensions (.so) for any .c or .cpp sources in
     the package.
[i] The endpoint script installs setuptools which indirectly adds this location
     to the python interpretter's site-packages directory.
     
Develop mode installs a package such that changes to the package
sources are immediately available to other users of the package.
This is useful for developing the package and installing hierarchies
of packages, without needing to reinstall after each change in the
source.

Normally, running

  python setup.py install

is sufficient.  However, if you are working on the sources and want
to be able to import the package without installing it, you may want
to use develop mode instead.

$ virtualenv tmp
$ cd tmp

Development mode works by performing an egg_info build in a .egg-info
directory (instead of building a .egg file) and putting it into the
install_lib directory (instead of the site-packages directory).

Setup scripts run from an egg are run with the working directory set
to the root of the egg contents (known as the "bundle directory").

By default, easy_install & pip are both configured to install packages
from PyPI. PyPI "distributions" are created by building an egg, running
egg_info or building a "binary" installer using bdist_* commands
included with setuptools.

Development mode is used in the following way:

$ python setup.py develop

This will build an .egg-info directory.

If you use pip, you also need to set the --editable flag:

$ pip install --editable .

以上示例中，我们通过调用develop__doc__()方法获取到develop命令的帮助文档，并将其打印输出。帮助文档详细介绍了develop命令的功能、使用方法和注意事项。
