Tensorflow会话-会话上下文的范围？

Question

import tensorflow as tf

...

with tf.Session() as sess:
    output = sess.run(result)
    print(output)

print(output)

为什么最后一行有效？由于output是在生成器内部声明的，因此不超出范围吗？

Answer 1

在python with中没有类似作用域的方法，这篇文章对此进行了更清晰的解释 Variable defined with with-statement available outside of with-block?

为了节省您一些时间

the context manager will be available outside the with statement and that is not implementation or version dependent. with statements do not create a new execution scope.
