In Python, the "not equal" operator is used to compare two values and determine whether they are not equal to each other. It is represented by the symbol !=. The result of the comparison is a Boolean value: True if the values are not equal, and False if the values are equal. ...

(stream-car (cons-stream x y)) x) #t scm> (equal? (stream-cdr (cons-stream x y)) y) #t 为了使流的实现能自动透明地完成一个流的构造与使用的交错进行,我们需要做出一种安排,使得对于流的cdr的求值要等到真正通过过程stream-cdr去访问它的时候再做,而非在用cons-stream构造流的时候就做。事实...
