Python字典不会像我想要的那样返回新的价值 [英] Python Dictionary Not Returning New Value Like I Wanted

问题描述

显然我做错了事情我是一个新的python / noob编码器，所以这可能是很明显的，但我不知道该怎么做。

 类英雄（）：
让我们做一些heros shit
 
 def __init __（self，name =Jimmy，prof =Warrior，weapon =Sword）： 
英雄构造器
 self.name = name 
 self.prof = prof 
 self.weapon = weapon 
 self.herodict = {
名称：self.name，
类：self.prof，
武器：self.weapon 
} 
 self.herotext = {
欢迎：问候，英雄，你的名字是什么？，
AskClass：一个好名字％s。你的班级是什么？％self.herodict ['Name']，
} 
 
 def thingy（self，textkey，herokey）：
n = raw_input（self.herotext [textkey]）
 self.herodict [herokey] = n 
 
如果self.herodict [herokey]！=：
 print self.herodict [herokey] 
 else：
 self.herodict [herokey] = self.name 
 print self.herodict [herokey] 
 
 def setHeroName（self）：
 self.thingy（ Welcome，'Name'）
 
 def setHeroClass（s​​elf）：
 self.thingy（AskClass，'Class'）
  / pre> 
 
 
所以基本上你运行它，它设置了一堆默认值。它会询问一个名称，并给它用户输入，并将Name键设置为输入的新值。他们假设要使用新的键：value或name：（userinput），并在下一个小句子中使用它。而是返回并使用默认值jimmy。 
 
 
 
我需要做什么？
解决方案
 
 AskClass：一个很好的名字％s。你的班级是什么？％self.herodict ['Name'] ，
  
在创建课程时执行，而不是在以后打印时执行。当您创建课程时， self.herodict ['Name'] 设置为'Jimmy'。
 
 
 
稍后您必须进行插值，当您确实有一个名称。也许你需要使用callable，如 lambda 对象：
  self .herotext = {
欢迎：lambda self：问候，英雄，你的名字是什么？，
AskClass：lambda self：一个好名字％s。你的班级是什么？ ％self.herodict ['Name']，
} 
  
然后调用它们传递 self 以后：
  n = raw_input（self.herotext [textkey ]（自））
  
 
So clearly Im doing something wrong. Im a new python/noob coder so it may be obvious for many of you but Im not sure what to do.
class hero():
    """Lets do some heros shit"""

    def __init__(self, name="Jimmy", prof="Warrior", weapon="Sword"):
        """Constructor for hero"""
        self.name = name
        self.prof = prof
        self.weapon = weapon
        self.herodict = {
            "Name": self.name,
            "Class": self.prof,
            "Weapon": self.weapon
        }
        self.herotext = {
            "Welcome": "Greetings, hero. What is thine name? ",
            "AskClass": "A fine name %s. What is your class? " % self.herodict['Name'],
        }

    def thingy(self, textkey, herokey):
        n = raw_input(self.herotext[textkey])
        self.herodict[herokey] = n

        if self.herodict[herokey] != "":
            print self.herodict[herokey]
        else:
            self.herodict[herokey] = self.name
            print self.herodict[herokey]

    def setHeroName(self):
        self.thingy("Welcome", 'Name')

    def setHeroClass(self):
        self.thingy("AskClass", 'Class')
So basically you run this and it sets a bunch of default values. It will ask a name, and you give it user input, and it sets the Name key to the new value of your input. They it is suppose to take that new key:value or name:(userinput) and use it in the next little sentence. But instead its going back and using the default value of 'jimmy'. 

What do I need to do?
解决方案
The line:
 "AskClass": "A fine name %s. What is your class? " % self.herodict['Name'],
is executed when you create the class, not when you later print it. When you create the class, self.herodict['Name'] is set to 'Jimmy'.

You'll have to do the interpolation later on, when you actually have a name. Perhaps you need to use callables instead, like lambda objects:
self.herotext = {
    "Welcome": lambda self: "Greetings, hero. What is thine name? ",
    "AskClass": lambda self: "A fine name %s. What is your class? " % self.herodict['Name'],
}
then call them passing in self later on:
n = raw_input(self.herotext[textkey](self))
