如何查找哪个函数来自"from - import"模块

Question

我有关于"from - import"函数。例如，我有3个文件:one.py, two.py, three.py.

three.py文件内容:

from one import *
from two import *

variable1
variable2
def func1()
def func2()
def func3()

假设我没有上述两个文件的权限，我无法打开它们。我的问题是，如何检查哪个函数和哪个变量成为从一个。py或两个。py文件?有什么命令之类的吗?

Answer 1

您可以使用inspect模块中的getfile

Return the name of the (text or binary) file in which an object was defined. This will fail with a TypeError if the object is a built-in module, class, or function.

https://docs.python.org/3/library/inspect.html inspect.getfile

Answer 2

print(func1.__module__)
print(func2.__module__)
print(func3.__module__)

Answer 3

您可以对import语句应用try-except。

try:
from one import *
from two import *
except ImportError:
# Override variables after failed import
var1 = ...
var2 = ...

Answer 4

你可以用模块的命名空间来调用函数变量

和检查与try/除了你不会抛出错误当你导入模块

try:
from one
one.foo()
one.variable1
except ImportError as exception:
print(exception)
try:
from two
two.foo()
two.variable1
except ImportError as exception:
print(exception)
