因为该函数代表了builtin__import__函数和importlib.import_module函数功能的主要相似之处。 This function represents thegreatest common denominatorof functionality between import_module and__import__. This includes setting__package__if the loader did not. def _gcd_import(name, package=None, level=0):...
To handle those situations, it’s always a good idea to use the timeout parameter of the run() function. Passing a timeout=1 argument to run() will cause the function to shut down the process and raise a TimeoutExpired error after one second: Python >>> import subprocess >>> ...

Python import 机制的起点是builtin module 的 __import__ 操作,也就是 builtin__import__ 函数。 Python 将寻找一切可以作为module的文件,比如subname 来说,Python 将寻找 subname.py、subname.pyc、subname.pyd、subname.pyo、subname.dll(Python 2.5 已不再执行dll 后缀名的文件)。
这种行为被称为memoizing（），很容易被实现为一个装饰器：import time import hashlib import pickle cache = {} def is_obsolete(entry, duration): return time.time() - entry['time'] > duration def compute_key(function, args, kw): key = pickle.dumps((function.__name__,...
