python模块中名称空间的命名冲突

Question

# module1.py

question = "What is the meaning of life, the Universe, and everything?"
answer = 42


# module2.py

question = "What is your quest?"
answer = "To seek the holy grail."




>>> import module1
>>> import module2
>>> print module1.question
What is the meaning of life, the Universe, and everything?
>>> print module2.question
What is your quest?
>>> print module1.answer
42
>>> print module2.answer
To seek the holy grail.

如果我们使用from module1 import*和from module2 import*，则会出现命名冲突，无法访问来自module1的问题和答案。为什么会这样？你知道吗

Answer 1

x = 'foo'
x = 'bar'
print x

这就是为什么。你知道吗
