Python 2.7 无法从其他文件构造类

Python 2.7 无法从其他文件构造类,python-2.7,canopy,Python 2.7,Canopy,以下是我的两个文件: Character.py def Check_File(fn): try: fp = open(fn); except: return None; return fp; class Character: ## variables ## ## atk ## ## def ## ## HP ## ## empty inv ## ''' init (self,

以下是我的两个文件:

Character.py

def Check_File(fn):
    try:
        fp = open(fn);
    except:
        return None;
    return fp;


class Character:

    ## variables ##
    ## atk ##
    ## def ##
    ## HP ##
    ## empty inv ##


    '''
    init (self, filename), 

    RETURN -1 == if the file is not exist
    RETURN 0 == all good

    all files will be save in format of

    "skill: xxx, xxx; xxx, xxx; xxx, xxx;"

    '''
    def __init__(self, fn):
        fp = Check_File(fn);
        if(fp == None):
            print "Error: no such file"
            return None;
        self.stats = {};
        for line in fp:
            nline = line.strip().split(": ");
            if(type(nline) != list):
                continue;
            else:
                self.stats[nline[0]] = nline[1];
                ##print self.stats[nline[0]]
        fp.close();


    '''
    display character
    '''
    def Display_Character(self):

        print "The Character had:";
        ## Parse into the character class ##
        for item in self.stats:

            print item + ": " + self.stats[item];

        print "Finished Stats Displaying";


print Character("Sample.dat").stats
另一个是:

Interface.py

##from Interface_helper import *;
from Character import *;

wind = Character("Sample.dat");


wind.Display_Character();
当我在Character.py中运行代码时,它给出

%run "C:/Users/Desktop/Helper Functions/New Folder/Character.py"
{'item': 'weird stuff', 'hp': '100', 'name': 'wind', 'def': '10', 'atk': '10'}
但当我运行Interface.py时:

我有

我想知道这段代码是怎么回事,我导入的方式是否错误?

不,您的导入没有问题。您确定两次跑步都在同一位置吗?由于代码只指定文件名,没有路径,因此python会话需要在
Sample.dat
文件所在的目录中运行。之所以问这个问题,是因为您在您的代码的中间定义了一个STATS属性。只有当文件不存在时才会发生这种情况(意味着它看起来不存在,而你正从那里运行)

python中的附言:

  • 行尾不需要分号
  • if
    语句中的条件周围不需要括号
  • 类应派生自
    对象
    类字符(对象):
  • Docstrings(在方法名称上方加上三个引号的字符串)应该在方法名称的正下方。这将允许ipython和其他工具在用户在其前面打问号时拾取并显示它们

很抱歉回复太晚,这非常有帮助,我会去仔细检查一下。非常感谢。前两个只是我个人对分号和括号的偏好。最后两个非常有用。再次感谢。
