Python内联Elif可能吗? [英] Python inline elif possible?

问题描述

'Hello ' + ('there' if name is None else name)

等于

msg = 'Hello '
if name is None:
    msg += 'there'
else:
    msg += name

这等效于什么:

msg = 'Hello '
if name is None:
    msg += 'there'
elif name == 'Mr Anderson'
    msg += 'Neo'
else:
    msg += name

这是我想缩小的代码供参考

srepr = '\'Modify '
if self.register == 'p':
    srepr += 'Pointer'
elif self.register == 'v':
    srepr += 'Value'
else
    srepr += 'Unknown'
srepr += ' By ' + str(self.delta) + '\''

推荐答案

msg = "Hi " + ("there" if not name else ("Neo" if name == "Anderson" else name))

不过，我认为这是很难理解的.

I think that's pretty unreadable, though.
