A finder’s job is to determine whether it can find the named module using whatever strategy it knows about. 搜索路径,不只是 sys.path 的所有路径,一些 subpackages 的查找可能依赖于 parent package 的 __path__。 import path: A list of locations (or path entries) that are searched by the ...

Relative imports...Relative imports use the module's name to determine where it is in a package. When you use a relative import like from .. import foo, the dots indicate to step up some number of levels in the package hierarchy. For instance, if your current module's name is package...
pickle.loads(data, *, fix_imports=True, encoding="ASCII", errors="strict") 从data中读取二进制字节流,将其反序列化为一个对象并返回。 在其中 我们可以看到 我们对象的属性 name 和 age 和我们所属的类 都已经存储在里面了 首先使用了pickle.dumps()函数将一个Person对象序列化成二进制字节流的形式。然...
from string import find print(find) 1. 2. 3. 那么python string/foo.py的运行结果会是下面的哪一个呢? <module 'string.find' from 'string/find.py'> <function find at 0x123456789> 按我们前面讲的各种规则来推导,因为foo.py所在目录string/没有string模块(即string.py),所以 import 的是标准库的st...
检查某模块可否导入 # 根据module_name搜索其父模块是否存在,返回父模块 or None parent_module = importlib.util.find_spec(module_name) 2. 包 Python 只有一种模块对象类型,所有模块都属于该类型,无论模块是用 Python、C 还是别的语言实现。 为了帮助组织模块并提供名称层次结构,Python 还引入了包的概念。
