Question

我正在使用LPTHW ex 41，在那里我们修改了一堆print语句以使用docstring样式，然后使用跑步者来打印它们。

代码最初是这样的：

Function()
Print "Several lines of printed material"

修改后，功能开始：

Function()
"""doc comment"""

跑步者连接所有功能（＆＃34;房间＆＃34;），目的是打印文档注释而不是打印命令。

ROOMS = {
'death': death,
'central_corridor': central_corridor,
'laser_weapon_armory': laser_weapon_armory,
'the_bridge': the_bridge,
'escape_pod': escape_pod
}


def runner(map, start):

    next = start

    while True:
        room = map[next]
        print "\n----------------"
        print room._doc_
        next = room()

runner(ROOMS, 'central_corridor')

但我一直收到错误

'function" object has no attribute '_doc_'

示例房间：

def central_corridor():
"""You wanna blow thing up.
You running toward place for to get bomb.
Emeny approach!

1 = shoot at enemy
2 = avoid emenemeny
3 = use bad pick up line on emenie
4 = hint"""

#print(_doc_)

action = int(raw_input("> "))

if action == 1:
    print "He shoot you first."
    return 'death'

elif action == 2:
    print "No he still gots you."
    return 'death'

elif action == 3:
    print "Oh yeah sexy boy."
    print "You get past laughing enemy."
    return 'laser_weapon_armory'

elif action == 4:
    print "Emeny like good joke."
    return 'central_corridor'

else:
    print "You enter wrong input"
    return 'central_corridor'

有谁能告诉我如何打印文档评论？谢谢！

Answer 1

注意到doc需要两个下划线。固定

_doc_

__doc__

Python 2.7，麻烦打印文档字符串（doc comments）＆＃34;函数没有属性_doc _＆＃34;错误
