小编wal*_*elb的帖子

我有一个 contenteditable div，用户可以在其中输入文本。我希望文本自动换行，但不像空格或连字符的默认换行，而是像这样：

This is some t
ext that conta
ins hyphenated
 words like th
is-thing-here,
 and also spac
es.

我怎样才能实现这个目标？

我正在尝试像 Curry 定义的那样实现 Y 组合器。

此代码不起作用。它会导致无限递归。

F = (lambda f: (lambda x: (1 if x == 0 else (x * (f(x-1))))))    
Y = (
    lambda f: 
    (lambda x: f(x(x)))
    (lambda x: f(x(x)))
)
Y(F)(3)

但是，这个确实有效：

Y = (
    lambda f: 
    (lambda x: f(
        lambda v: x(x)(v)
    ))
    (lambda x: f(
        lambda v: x(x)(v)
    ))
)
Y(F)(3)

为什么第一个不起作用，而第二个起作用？

我尝试列出以“\t”开头的所有安装点：

with open("/proc/mounts") as f:
    mountpoints = (
        [list((filter(lambda s: s.startswith("/t"), line.split(" "))))
         for line in f if
        (lambda l:
         list(filter(lambda x: x.startswith("/t"), l))
        )(line.split(" "))])
    


print(mountpoints)
#[['/tmp']]
#this is correct, however I want to remove one pair of brackets

print(*mountpoints)
#['/tmp']
#this works!

m = *mountpoints
#SyntaxError: can't use starred expression here
#but this doesn't.

为什么最后一个作业不起作用？与 print 语句有什么区别？

感谢帮助！
