動態創建函數具有特定名稱

Question

我就倒閉閱讀幾篇文章，而不是，但即時通訊試圖創建一個特定的命名功能是什麼

from app.conf import html_helpers 

# html_helpers = ['img','js','meta'] 

def _makefunc(val): 
    def result(): # Make this name of function? 
     return val() 
    return result 

def _load_func_from_module(module_list): 
    for module in module_list: 
     m = __import__("app.system.contrib.html.%s" % (module,), fromlist="*") 
     for attr in [a for a in dir(m) if '_' not in a]: 
      if attr in html_helpers and hasattr(m, attr): 
       idx = html_helpers.index(attr) 
       html_helpers[idx] = _makefunc(getattr(m,attr)) 

def _load_helpers(): 
    """ defines what helper methods to expose to all templates """ 
    m = __import__("app.system.contrib.html", fromlist=['elements','textfilter']) 
    modules = list() 
    for attr in [a for a in dir(m) if '_' not in a]: 
     print attr 
     modules.append(attr) 
    return _load_func_from_module(modules) 

IMG返回像這樣修改字符串時，我打電話_load_helpers我想要將現有的字符串列表修改爲即時調用的那些函數。

這是可能的，我在作出任何意義，因爲我很困惑:(

我覺得應該functools.wraps做你想要什麼：

from functools import wraps 

def _makefunc(val): 
    @wraps(val) 
    def result(): 
     return val() 
    return result 

>>> somefunc = _makefunc(list) 
>>> somefunc() 
[] 
>>> somefunc.__name__ 
'list'
