Standard Library简介 python标准库内置了大量的函数和类,是python解释器里的核心功能之一。该标准库在python安装时候就已经存在。 python内置对象 内置函数:Built-in Functions 如print() 内置常量:Built-in Constants 如false 内置类型:Built-in Types 内置异常:Built-in Exceptions 如何安装发布第三方模块 自己发布自己...
实际上“动态加载”真实含义是将这个module 以某个符号的形式引入到某个名字空间,del xxx 只是删除了符号,而sys.modules 中仍然维护了xxx 对应的module 对象。如果我们更新了module A 的某个功能实现,可以使用 reload 来更新 sys.modules 中维护的module A 对象,注意:Python 虚拟机在调用reload() 操作更新module ...

导入期间,如果在sys.modules找到对应的模块名的键,则取出其值,导入完成(如果值为None则抛出ModuleNotFoundError异常);否则就进行搜索操作。 sys.modules是可修改的,强制赋值None会导致下一次导入该模块抛出MoudleNotFoundError异常;如果删掉该键则会让下次导入触发搜索操作。 注意,如果要更新缓存,使用 删除sys.modules的...

Python has the built-in venv module for creating virtual environments. This module helps you create virtual environments with an isolated Python installation. Once you’ve activated the virtual environment, then you can install packages into this environment. The packages that you install into one ...
通过setup函数的参数packages、include_package_data(其实就是MANIFEST.in文件)、exclude_package_data、package_data、data_files来指定需要打包的文件。 包含的文件如下: py_modules和packages 参数指定所有 Python 源文件 package_data和data_files 参数指定所有数据文件。data_files指定安装过程中,需要安装的静态文件,如...
This precedence can cause conflicts when built-in modules have the same names as directories in your code. When running in a Consumption plan or an Elastic Premium plan, conflicts are less likely because your dependencies aren't prioritized by default....
